Deep Dive is an ongoing Gamasutra collection with the purpose of shedding gentle on particular design, artwork, or technical options inside a online game, in order to point out how seemingly easy, elementary design choices aren’t actually that straightforward in any respect.

Check out earlier installments, together with creating the placing pixel animations of Crawl, attaining seamless branching in Watch Dogs 2’s Invasion of Privacy missionsand creating the intricate degree design of Dishonored 2‘s Clockwork Mansion.

Hello, my title is Henri Mustonen. I have been with Housemarque Since 2009 and labored with such titles as Dead Nation, Outland, Super Stardust Delta, Resogun and Alienation. My work entails recreation design and degree design.

For these unfamiliar with Nex Machina, it’s a quick paced twin-stick arcade shooter with deep scoring mechanics. It’s a collaboration mission with Eugene Jarvis, and it’s impressed by Robotron 2084.

“Instant motion. Eliminate downtime as a lot as potential” was considered one of our guiding ideas when designing the core gameplay. We wished gamers to be immersed from the very begin of the extent and to maintain the motion ongoing. This meant we wanted to chop as a lot of extra fats as potential and determine what was actually essential to get the sensation you might be on the “knife’s edge”.

You enter a degree, rescue people, kill all of the enemies and then you definitely fly to the following. The development is kind of quick and also you gained’t be caught in a degree for greater than round 15-30 seconds.  You want to have the ability to learn every state of affairs in lower than a second and type a battle plan based mostly on that. That means we have to have the precise challenges, entity behaviors (people and enemies) and the results of your actions actually apparent so you may make good moment-to-moment choices.

Urgency can be an vital level. We need you to prioritize issues and attempt to do your greatest in a restricted timeframe.

The One Second Plan

We are asking the participant to stability a number of issues throughout gameplay. Layouts, people, enemy spawns, dashing, secondary weapon, secret exits, customer patterns, beacons, random Disruptor enemies and so forth. 

”Ok now I flew to a brand new degree, I have to rescue the people, shoot this turret that is bothering me – but when I spend time on that, then I miss the momentary bonus enemy on the other facet”

The extra issues we’re asking you to do in a restricted time the extra swift you could be in you prioritization. You can’t do all the pieces until you propose your gameplay. So everytime you enter a degree, you formulate an preliminary plan of motion and just about go from there.


The first, most evident factor you observe after touchdown, is the format. Clear adjustments in shapes, sizes and traversable areas are important as a base to construct from. We wished all of our layouts to be open so you’d stay in hazard all through the extent since there may be nowhere to cover. Starting location of every room determines how you might be to navigate it and what choices you have got. If we felt some ranges wanted to have extra depth, we usually experimented transferring the participant spawn into the center of the room. That made you particularly weak to any upcoming assaults and provides the sensation of unease. As a rule thumb, we wished to make an effort to position the participant in hazard. 

With the continuing strain of enemies, it is very important have the layouts immediately readable with colour variations between walkable areas and non-walkable areas. We wish to offer you as clear data as potential on the place to navigate and what areas will trigger you lifeless ends.

Enemy placement

On our exams, considered one of our followers identified the most effective ranges at all times had preliminary pre spawned enemies ready for you earlier than new ones spawn. That served to maintain up the tempo and offer you an preliminary problem as you might be saving the people. It additionally acted as an introduction to the upcoming degree’s guidelines and enemy utilization. Often instances you bought a style on what to anticipate.

Most of our enemies are positioned as teams, not as particular person enemies. Generally we place splines, portals and space spawners and outline how these are populated. Enemy sort, quantity, path, spawn frequency and so forth. We discovered that spline like shapes have been most recognizable and felt essentially the most enjoyable to fight as a participant. You study the overall shapes of spawners in every world and subconsciously you might be finishing the shapes inside your head throughout the spawns. That offers you a small higher hand on the enemy spawns as you study these.

As far as placement goes: we wished to play with the strengths of every format and encourage you to navigate them utilizing enemy spawns together with people. We wish to pull you in and draw you away utilizing the spawns. The extra we will make you progress and dance in the format the higher. 

Most spawns occur with a fairly speedy interval. This is that will help you prioritize and perceive what’s going on in the playfield. If we had 5 lengthy, impartial spawners for instance, spawning with totally different paces, it’s laborious to maintain up what comes subsequent, which spawner is accomplished and so forth. It’s way more enjoyable to have small compact challenges that you may overcome and transfer on.

Human placement

The people are fairly senseless creatures, absorbed in their pill gadgets, wandering across the playfield with no concern for their very own security. Your purpose is to save lots of the people for varied rating and token drop advantages.

All ranges’ people are seen from the beginning, at all times. It offers you a plan of motion when coming into a brand new degree. This additionally gave us sure anchor factors for degree design since we will belief gamers to attempt navigating by them. Added to that we additionally had Harvester-enemies that attempt to seize people so you could go to their support earlier than they’re killed.

We wished to create a way of urgency as usually as potential by having people threatened by Harvester-enemies. If you might be enjoying for prime rating, you don’t rescue all people without delay(your combo will drop), opening extra alternatives for the Harvester enemies to seize the people throughout gameplay. This is among the methods we power gamers to re consider their recreation plan once they see a human is in hazard that that they had left on it’s personal gadgets.

The Plan

Forming a plan of motion based mostly on the format, preliminary enemy spawns and human placement, gamers get a fast concept of what they should do and in what order, and so they can start to navigate the extent accordingly. Next you simply need to see how the extent begins unfolding and modify.

Best Laid Plans

After the beginning of every degree we wish to add strain and one thing to shoot at, always. We need you to expertise a way of urgency that if you don’t take care of the challenges offered proper now, they may escalate. We use enemy accumulation and human threats for this. We don’t actually attempt to cease gamers from feeling overwhelmed. It’s primarily as much as you to prioritize accurately and management the playfield along with your toolkit.

There is a stability although. We may simply spawn all the pieces on the very begin of every degree and be executed with it. You type it out! Understandably nonetheless, we wished there to be stream with the challenges that we give to the participant with out the degrees being too entrance or again heavy. Levels begin with a style of what’s to return, increasing on that after which ramping it up. We wish to maintain you in that engaged state so long as potential and “ready for one thing to occur” isn’t partaking. Nor is frustration over unattainable odds.

We are mixing time and occasion based mostly triggering for the spawns. Time based mostly ones act independently of your actions and occasion based mostly usually act on enemies killed. This was to offer some predictability and construction with out being too apparent. Every degree tends to unfold a little bit otherwise every time you play it.

Some ranges even have extra parts like randomly spawned disruptor enemies, customer teams you could find and destroy earlier than they disappear, beacons you could destroy and secret blocks you could blow up. We overlay these parts together with common gameplay to deliver additional challenges.

The degree gameplay iteration wasn’t actual science. Generally we simply saved our eyes open every time there was a degree that was clearly above the others and paid consideration to it fairly naturally. Those have been simply actually enjoyable to play! Most of the time although it was enjoying and replaying the extent many times over a protracted time frame. Something may really feel good for a day or two, however after per week you begin seeing it’s faults and the way it not holds up. Then you iterate it extra or attempt one thing else. In common although, we didn’t settle over a constructive first response. We wished the primary and lasting impression of every degree to be gratifying.

Enemy synergy – Maintaining the stream

In every world it was vital to seek out good synergies between enemies in order that they are often blended nicely and supply attention-grabbing challenges. Requiring totally different approaches/options from you. We need gamers to really feel that they managed to beat the chances by studying the playfield and doing the most effective resolution accordingly in a short while. Understanding the enemy behaviors, prioritizing essentially the most harmful ones, then utilizing your toolkit to destroy them as quick as potential is difficult and rewarding. Keeping you on the knife’s edge.

We have a distinct pool of enemies allotted for every world(excluding the ultimate). On a excessive degree we aimed to have taking pictures enemies that encourage dashing, medium / excessive sturdiness enemies for secondary weapon use and primary popcorns that offer you most freedom on learn how to method them. You won’t encounter solely small mutations of the identical enemy all through the sport however have to adapt to every world and it is challenges. 

We are attempting to handle what kinds of issues we require from you. The clearer the aim of an enemy, the clearer it’s what it requires from the participant. It’s additionally simpler to couple clear function enemies with one another and make extra intentional gameplay. Enemies that fight over the identical function usually don’t sit nicely with one another or actually deliver something new when used in the identical world.


We are asking rather a lot in phrases of stress and a spotlight so managing that’s actually vital. Levels have to have selection in phrases of issue and challenges we current. We wished to keep up a gradual development however have extra manageable components as nicely.

We wished the degrees to have a transparent id and phases inside them. If you might be simply bombarded with always spawning enemies with none clear logic, it feels messy and taxing. The recreation does not really feel nicely thought out. Granted that may be the expertise for some at first however the additional your abilities improve in prioritization and enemy controlling, the extra you begin seeing patterns and phases in the degrees. Finding order and guidelines among the many chaos turns into enjoyable.

Spawning the enemies themselves must be readable and have a transparent rhythm. Things must be spaced out in good style and never for instance be too entrance heavy. Spawn frequency and placement additionally play an element right here. While enjoying, you unconsciously allocate sure components of the format to have spawns/be harmful. Having these simply groupable areas makes the gameplay extra comprehensible. 

You have to create a dialogue with the participant on how the world works. Timing and grouping are essential in that. Having clear waves and phases assist management and perceive the continual swarms of enemies. Rules of spawning, recurring patterns, spawn intervals and so forth. 

  • “Big hand enemy at all times on the middle after a while has handed”
  • “Lines of popcorns showing to the perimeters of the room with a quick interval”
  • “That one level in the center when each spawn”
  • “Those Four-way bullet enemies that lure me in the direction of the top”

Waves and phases inside a degree offer you a psychological checkpoint on how far you bought in the extent and what occurred in it. Not utilizing all world’s enemy sorts without delay makes the challenges extra recognizable as nicely and provides the enemies their very own highlight ranges to shine in.

Layouts outline how laborious you may hit the gamers. If you might be navigating a big format, you clearly have extra selections and methods to to deal with any given state of affairs. So the smaller the format goes, the much less room for error gamers have and the extra stress you endure. Naturally the enemy sorts themselves and the way they’re blended play an vital function on how taxing issues get as nicely. Small layouts can stay simple if you’re offered with solely popcorns for instance.

Eliminating Downtime

In the top of every degree the motion begins to peter down, the ultimate enemy is highlighted and upon destroying it, you might be offered with the top degree minigame earlier than flying to the following degree. This serves as a breather and a quick heads up for the upcoming degree. However it doesn’t last more than a few seconds. We wished to maintain the loop tight between ranges so that you don’t go chilly and nonetheless bear in mind your human combo from one degree to the following.

In an early construct we had the participant navigate to a degree exit block when ending a degree. Upon touching the block they’d fly to the following degree. This made some ranges last more than they need to have because you wanted to seek out the exit and relying in your playstyle, you’d find yourself in a distinct a part of the extent per playthrough. Sometimes near the exit, different instances on the other facet.

In the ultimate system the top degree sequence is automated, beginning as quickly as you kill the final enemy. You can pace it up and acquire additional factors when you succeed in the top degree minigame, ensuing in an nearly instantaneous transition to the following degree regardless of the place you might be.

We usually aimed to point out you any upcoming ranges whereas enjoying the present one so you have got a obscure understanding of what’s to return even when you don’t consciously give it some thought. It additionally makes the world really feel extra alive because you see playable areas throughout you, not solely set dressing. 

It took a stunning quantity of labor to have the degrees positioned in relation to one another in a manner that ‘felt’ good. We wished to keep away from the development changing into uninteresting and repetitive. We positioned ranges sideways, the wrong way up, left, proper, up, down in relation to one another. This made the extent to degree transitions extra enjoyable and enabled us to point out attention-grabbing areas. We additionally used rotated ranges to combine with expectations each as soon as in awhile.

We had a ‘purpose path’ guiding the general placement of ranges so you may considerably perceive what the general path is. In the lava world, you see glimpses of the underside lava pit by a number of ranges and in the City you see the ominous tower on the background as you progress, lastly ending up in each goal places. 

In Nex Machina we wished to create a throwback to the pure classical arcade expertise. Intense, quick motion with out cutscenes or something to attract you out of the motion. We wished the gameplay to be actually tight. Many of us are large followers of Robotron so collaborating with Eugene Jarvis was a dream come true. Modernizing the tried and examined gameplay with new parts and new choices for the participant was actually enjoyable to do.

Establishing the Knife’s Edge precept helped us make higher choices and transfer ahead with a guiding gentle. Naturally it took a while and sitting down to call it, perceive what it meant and learn how to emphasize it.

We had loads of concepts on what to check out and even our worlds (Forest, City, Labs, and so forth.) have been initially round 50 ranges lengthy. All worlds ended up being 15 ranges. That is among the extra concrete examples of slicing extra fats to not drag issues too lengthy for their very own good. We wished to finish up the most effective and most partaking content material potential.

Whenever we might play the sport, blasting by totally different enemies, rescuing people and transferring round felt nice. The longer it went on, the extra engaged you began to really feel. When you wanted to attend for brand spanking new spawns or stroll to a brand new space in order to progress, it broke the stream and drew you again from that engaged state. Then you wanted to work once more to get there. Cutting extra fats from enemy spawns, degree transitions, and utilizing compact layouts helped staying in “the zone”.
