Creeper World 3 is what happens when cellular automata takes over a strategy simulation. Instead of discrete units that attack your base, a fluid-like substance spreads over the terraformable terrain. Your base, your weapons, your strategy... you must adapt them all.

About This Game

Creeper World 3: Cellular automata takes over a strategy simulation.

Instead of discrete units that attack your base, a fluid-like substance spreads over the terraformable terrain. Your base, your weapons, your strategy... you must adapt them all.

Creeper World 3 bends what it means to be a strategy title.

Instead of heavily scripted A.I., players find themselves engaging an enemy with theoretically predictable behavior yet which is shockingly interesting to engage. Players can build fortifications and stick around forever. Players can go for domination, quick strategic kills, or amass huge stockpiles of resources. Some play for speed, others to create art. Tiny maps, large maps, five minute missions, five day missions... the simulation scales to handle all of these scenarios.

User generated content is critical and supported at multiple levels in Creeper World 3.

Dial up worlds using the DMD (Dial Map Device) and tweak dozens of constraints. Then, play and share the addresses via an on-line database. Create your own maps using the built-in map editor and upload and share on-line. Or, join with thousands of other players and peruse the databases of worlds created by others. Want to create a new weapon, a unit, an enemy, or an effect? Use the built in scripting language to create what you dream. Hundreds of engine commands are exposed and examples abound on the forums and grow daily. You can even take the built in story maps and make your own. In fact, all of the built in story missions were written using the built-in editor and the CRPL scripting language.

Some of the high level features are:

  • Thermodynamic/fluid physics based play.
  • Billions of total missions.
  • Story arc with insane and unique enemies.
  • Explore hundreds of star systems with thousands of worlds in Prospector missions.
  • Hundreds of hand crafted missions in the Alpha Sector.
  • Dial up your own mission worlds using the 'Dial Map Device' and share the address.
  • Create your own maps using the included map editor.
  • Play on maps of variable size, dimension, and shape.
  • Script your own enemies and effects using the built in scripting language.
  • Terraform the landscape during missions to take the higher ground.
  • Discover experimental weapons that devastate the enemy.
  • Share thousands of unique maps with an established, enthusiastic on-line community.
  • Features a unique, original, and awesome soundtrack.

Combining the best of CW 1 and 2 in the form of CW 1.

I liked the previous Creeper World games you will like this one as well.

A perfect specimen of what I call Strategic Survival. You are terribly outnumbered and first have to set up a defensive line and survive and gather strength. Then you can roll out and bring the fight to the creepers.

I could tell you stuff about the gameplay and story, but if you didnt already like the game by the video and looking at the screenshots nothing I could say would persuade you.

its fun but it has some things that i hate like fabor a timed world when i like to do this slowly and see my base and build 60 power base with walls of guns so fabor was like GO GO GO and i was all like no no no so i did not beat the game . but its fun and even when i make a huge base it still runs no frame drops.

If you are a fan of the series, I don't think this will disappoint you. You have a great campaign that I feel tells a great story, not only that but it allows you to pick up and play a randomly generated mission and challenges.

If you are new to Creeper World, pick it up cheap in the sales, still worth it.

10/10 Would creep again.

- It's a good strategy game, well polished with few issues if any, and it's quite fun, it's worth the money, and will offer many hours of gameplay with thousands of missions to choose from, including player made missions.

This game is very much worth both the money spent buying it and the time spent playing it. It is a major time sink, hours go by without me even noticing. There's hundreds, even thousands of different maps and missions to choose from.
Personally my favourite section is the player made custom maps and missions, they feature many different scenarios and events, even some new things not present in the base game like new units and new enemies. It's really great seeing all these things people have made, there's strategic maps people have made where you have to plan ahead and think carefully, wacky maps that are fun and light hearted, play as creeper maps where the role is reversed and you are the creeper assaulting a base, custom scenarios of different kinds made by people, it's all varied and quite fun to play.

Another feature is a random map generator, where you put in the features you want, like map size, terrain type, and other variables, and the generator will create a random map based on what you want from it. For people who want a challenge, there's a section of the game dedicated to randomly made extremely difficult maps, some of which are literally impossible, others close to that. Most of them can be done, but they require a lot of thought and careful action to get there. For people who want a more casual experience there's a section dedicated to easier maps that have items called "artifacts of Odin", and the goal is to collect these items scattered throughout the various planets. There's also a campaign which features some interesting levels which teach you the game, some of which are quite tricky.

The premise is that there's this entity called the creeper, that has been ravaging the universe for a long time. It spreads from planet to planet, creeping across like a liquid, and it is your job to simultaneously put up a strong defence to hold back the tide and to also effectively assault the source of this enemy. It's a cross between a tower defence, real time strategy and management sim all in one. You have to position your units, manage supply lines, organise your base, respond to the changes of the battle, manage your resources, extend out in an effort to attack whilst at the same time making sure your defences will hold. You have to be careful with what you do and choose a playstyle, do you turtle up, building up a strong defence capable of weathering the incoming assault at the cost of allowing the creeper to multiply thus causing future expansion to be slower, or do you reach out early for a preemtive strike, weakening the creeper early or gaining a strong foothold, at the risk of overextending and leaving gaps or weaker parts of your defence? There are different ways of playing this all depending on your own individual playstyle and what is better for the map you are playing.

You can play this at your own pace, there's the option to play it at normal speed, 2X, 3X or 4X speed, and you can also pause the game and issue orders whilst paused, useful for assessing the situation on a large map where a lot of things are happening at once and you need to be controlling the battlefield in all these areas simultaneously.

In terms of stability, this game is very stable, there's few bugs (I'm not even sure I've noticed any), it runs well and doesn't require high specs. It's a lot better in this regard than many big name titles made by whole studios, and this was afaik made by one person.
There's a fair amount of UI options and a few graphical options which are all quite nice to have.

Buy it, especially if it's on sale!

- Relaxing, yet rewarding, RTS experience
- Campaign missions are interesting and unique
- 100+ hours to complete the campaign missions (probably, not done yet)
- Map maker
- Community-made maps
- Random map generator (a.k.a. Dial Map Device)

- Storytelling tries to be way too "epic" but is simply tedious (maybe the later missions will make up for it?)

This game is a perfect match for me. It's an RTS, but you basically set your own pace, so it's much less stressful than something like StarCraft. Don't get me wrong, I love StarCraft, but Creeper World 3 somehow manages to make the RTS experience relaxing and rewarding at the same time.

At the time of writing this review I have about 19 hours in the game, and I've barely scratched the surface of the content available. I'm maybe 1/4 of the way through the campaign missions, and have yet to play any of the thousands of player-made maps, or the practically infinite map generator called Dial Map Device.

The campaign missions are interesting, and somehow keep surprising me with new challenges. The storytelling is pretty bad, though. I feel like writer tried too hard to make it feel like a super epic novel, but it just ends up being tedious.

Overall it has been well worth the $2.99 I paid for it. Having experienced it, I would have easily paid full price for it.

I am frustrated with this game. Because:

When I first started playing it I thought it was going to be my new favorite game. And it was for like a week. But of course the "introductory phase" is never the same as when you get into the "meat" of a game, and that's where things got frustrating.

Mainly cuz it's just boring. Feels like a game in search of an x-pack (at least one x-pack!)

Not enough diversity in terms of friendly or enemy units/activities = not enough diversity in gameplay overall = game gets boring real quick.

Map-wise, no complaints about the amount of content. There are hundreds if not thousands of maps I have not played, and theoretically unlimited content via parametric map generator and fan-made content. But the actual gameplay is so boring I would basically have to force myself to play it at this point. (Achievements, u know...)

The usual response to the "boring" complaint is that "you are playing it wrong". (IKR?) People apparently get a kick out of playing this game in a "speed run" style, because high scores are based on speed. At that point, though, it becomes more of a puzzle game and those just don't interest me at all. (Or at least, they interest me extremely rarely...)

One thing that might alleviate the tedium a little is if there was smarter UI logic/assistance when it came to placing your collectors (basically solar power plants which you have to at least attempt to place somewhat optimally or they are useless). Right now you can semi-automatically lay them out in a line. This game would be less of a criminal against humanity if you could quickly lay them out in a grid. (i.e. keep the exact capabilities of the current placement "tool" and just make it work in 2 dimensions instead of just 1.) I find myself spending a lot of time doing these tedious set-ups at the beginning of each map, that practically take as long as the gameplay portion.

But of course the pros are like "you are not supposed to be building 200 collectors and spending 45 minutes on a single map!" OK, but even when I play short games, the setup takes too long.


So, while I ultimately don't "NOT RECOMMEND" this game

-- as critical as I am, it actually takes a LOT for me to "NR" --

if I was looking for a pure Tower/RTS-defense kinda game... I'd appreciate the advice if someone told me my time was probably better spent elsewhere.

(And that being said, I'm not 100% sure but I think I got this game in a bundle and probably effectively paid <$1 for it so .. not like I rly regret buying it anyway. I just regret becoming infatuated with it before I knew what it really was.)

Today I redeemed my £30 Steam cards.

"What shall I buy?" I pondered.

This game is heavily discounted at £2.19 and was on my wishlist, so I purchased it and I'm glad I did.

Well worth the money, I haven't played enough to see if it's worth the full price of £10.99, but this gem has got it's hooks into me, and that's not an easy thing to do.

Well worth the £2.19, this is already one of my favourite games.

Reminds me a lot of a game I used to play back in the day called 'Colors of War.' On the off chance that you have any idea what that game is, and enjoyed it... Then get this game.

For the majority of you that never played it, the concept was about trying to paint the map in your color using bizarre means, all while fighting off the enemy colors and trying to retain the grounds you gained, in real time. Arc Eternal builds on that same concept.

There is an enjoyable trance this game seems to lull me into. It feels like a familiar formula, but plays out in a nuanced and original fashion.

15 bucks is a pretty steep price for what it is imo, so I would snag it on a sale. I'd drop a 5 dollar bill on it any day though.

Just when you think you are winning think again. So simple and yet so addicting.

Play thousands of player created scenarios, billions of random maps or create your own with powerful tools.
Only con is you have to complete specific story (tutorial) missions to unlock all functions (but it is not very long and it is useful for new players).

Best of all there is unity demo to try (you can also try first two just for fun).

The best combination of Tower Defense, Real-time strategy and Resource management.
Unique and fast-paced gameplay along with stunning storyline.
This game is already one of my all time favorite <3

Graphics yet simple but fun. for $3 with so much content, it's a no brainer for any TD, RTS gamer.
worth every single penny :)

10/10 Ultimately recommended

I hate this game. You should never get it. Seriously. Once you have this, it will be a time sink forever. You can never finsh this game. It's a deceptive little game - you may think - "oh, there are only 23 missions in the Story then I'm done." But it's not so easy. Along your way you will unlock untold millions of additional maps. Then you can't stop playing them.

I have been playing Creeper world since 2009 and I can't stop. I need to join the Creeper World Anonymous club and confess "Hi, my name is Karsten and I can't stop killing Creeper."

You can play in the Tormented Zone if you are a masochist and like inflicting pain on yourself. Some worlds in there are documented unwinnable - but that won't stop you from trying - it didn't stop me.

Occasionally venture into Prospector zone and pick up a few Artifacts of Odin - the mightiest weapons mankind did not invent.

Try out the Alpha sector. Made by those early beta testers. Made to be difficult. Make sure you try Virgil's Brainic map. Just to see how weird you can get.

Like Shooters? Try out the Credits mission. Hey, my name is in there somewhere - so are all the other beta testers. :)

If that's not enough, go dial up your own maps in the DMD (Dial Map Device), Here you can make a world with the click of a few buttons. Add ingredients to suit you and cook up a hard challenge or a speed run - win it, name it and share it with all us us addicts. Oh wait, I'm trying to stop playing. Don't share it.

Finally, if you are creative, inventive and perhaps you like to add custom units and styles, make your own map in the Projects Editor and share it in Colonial Space. Here there are no rules. Maps are all over the place, fun, hard, tricky, unusual, huge slog-fests, or tiny puzzles. As large as 256x256 or as small as 20x20. Don't say I didn't warn you. This is where "map rage" goes to live after you discover it at Farbor (the timed mission in the Story arc).

I would tell you more, but it's time for my fix and Im heading out to the DMD to get a quick fix.

Oh yes, "Hi, my name is Karsten and I am killing Creeper."

Nearing the end of a mission, I look at the way I have networked my collectors across the map. How I have inched my way from one edge to the other, covering everything in my wake, destroying the creeper in my way.

And I realize, the creeper and I, we aren't so different.

I think Creeper World 3 catches a lot of people off guard because of the cheap price, low resolution graphics and understated appeal. It also gets called a Tower Defense game a lot, which does the unique strategic components a horrible injustice. Instead, Arc Eternal is a laid-back thinking mans' RTS with unprecedented play-more value and excels as a game you can sink some time into in the form of a well thought out and strictly controlled approach, or as a casual attack on a map every now and then. It's like Civilization V in the respect that you'll launch it for a quick 20 minute game and find yourself embroiled in the relentless depths of an alien planet fighting to make a foothold on a section of map on the 4th planet of your 3rd star system 6 hours later, wondering where the time went.

The amount of content in here is staggering, and the campaign provides such a good learning curve and introduction to the new structures and some possible strategies that can't be praised enough. There's also an engaging backstory in the main campaigns which help you feel isolated and alone while fighting the uncaring, unforgiving creep, and while the dialogue is cliche at times, it helps bolster the already engaging gameplay and add a little depth.


The best part of this game is simply the gameplay. While the tower defense mechanics have been done to death and don't offer anything particularly insightful, the different natures of the two opposing forces here make for a level of adaptable strategy that you wont see in many games. The structures are all balanced and simple but effective additions like Terraforming and one-use items make for even more ways to play and even more things to spend time working on.

The sheer amount of content is the other great part of this world, and deserves praise.

* The first port of call is the Arc Eternal which acts as the campaign mode and teaches the player the basics and structures, and consists of 9 star systems for a total of approximately 50 levels.
* There's the Alpha Sector which includes many early maps and a ton made by the alpha and beta players.
* The Prospectors Zone features procedurally generated maps.
* There's Tormented Space for those seeking challenge which includes maps from hard to literally impossible.
* The Dial Map Device acts as a map generation tool and lets you play more specific maps.

Mistakes & Annoyances

For many, the simple enemy A.I. is an issue here, and it can be argued that the very flat nature of the enemy intelligence makes for a somewhat bland approach. I'd counterargue and say that this game is more about finding solutions you like, and/or finding the optimal or most efficient route to victory and that the focus doesn't need to be on the creep.

* The difficulty curve isn't very smooth, and you can find yourself struggling way beyond what you'd expect in some of the later campaign missions, or struggling to overcome frustrating maps. There are also several outright impossible missions which nobody has yet been able to find a solution to.


Arc Eternal comes priced at £10.99/14.99€/$14.99 and while it contains a huge amount of play time, including a main story of at least 15 hours, it's still probably slightly overpriced for most players when compared against competitors. It's one of those games which you'll either love or hate, and so playing the demos listed below, or the flash versions of the developers other titles before making a full priced purchase is recommended.

* If the huge amount of content included by default wasn't enough for you, there are a ton of user maps too with different types of play. There are even Play as Creeper style maps.
* Some of the earlier titles are also available for free play in Flash on Kongregate.
* There are demos of all 3 of the Creeper World games available on KnuckleCrackers' website which are much shorter.

Same as the flash game of the same name, with a bajillion times the content. One of my favorite strategy games because it cares more about logistics than twitch or line graphs.

I don't know what it is, but supply lines get me wet.
