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.

Very good game, but sometimes it gets boring because there are so few useful offensive towers. Mortars are almost useless at actually holding back creeper, and jets are too expensive for starting off, and do very little individually. So just spamming cannons is the best way. Bombers and sprayers take way more AC than you can produce, and snipers only shoot drones.

But the game itself is still extremely fun, and I would recommend

The Creeper series is in a sort-of RTS style, with no AI. Creeper is represented as a blue fluid that damages player structures when it comes in contact with them. It spawns at set intervals, gradually filling the entire map if left alone. The general objective in Creeper World 3 is to battle through the Creeper and destroy the spawners by building nullifiers next to them.

The game can get quite challenging, and perhaps impossible, if the player has trouble getting enough resource production to output enough damage to Creeper before it engulfs the player's base. Like any RTS, there is a build order to learn and practice, but one key difference is the pause button, resulting in a less intense "RTS" game. There are hundreds of hours of gameplay, not including user-created custom levels. Nice concept and fairly engaging story.

The original concept for Creeper World 3 can be found on Armor Games, where a series is dedicated to the blue fluid, so start with those shorter titles if you're not ready for Creeper World 3.

Some are calling this tower defence. I'd call it real-time strategy. Regardless, I don't normally like tower defence or RTS, but this game is the exception to both. Maybe that's because this game takes those ideas and adds a simple but robust concept for the enemy units that you're fighting against.

The best news for you is that you can play a free demo of all the Creeper World games on the web via Flash or Unity webplayer. If you want to find out what people are gushing about, just go try the demo. You don't have to download anything (other than the browser plugin), just play it in your browser. If you like tower defence or RTS, definitely play the demo. Even if you don't, but you're somehow reading this out of curiosity for this game, try the demo anyway. Take if from a guy who normally dislikes both of those genres, and just look at how many hours I've played Creeper World III.

This is essentially a much-improved version of the first Creeper World. The game has a built-in map editor, and also seed-based procedural generation for random maps. This is in addition to hundreds of pre-made maps of varying difficulty.

As of the time of this writing, this game still has an active community of dedicated and gifted players who are still adding custom maps each day. There is much opportunity for modding. In addition to the map editor, there is a built-in scripting language so you can essentially reprogram the game (within limitations I imagine, as I've never personally experimented with it), and I've seen players come up with some very creative ideas such as maps where you play as the Creeper and maps where the enemy has units similar to your own that are controlled by AI, maps with fog of war, maps with booby traps, and the list goes on. The mods and customization make available endless hours of entertainment.

Let me start off by saying: Wow.
For a game as simple as this, you sure get your bang for your buck.
It's a tower defense game with a bit of resource management. It's fun to watch as the purple and (eventually) blue creeps battle for control of key points. There is a fairly gradual learning curve, with the final couple levels being seemingly impossible. However, you'll find out about efficiency, and how to place your turrets and anti-spore lazers more effectively. With an online community making levels, you're in for hours upon hours of simple tower defense gameplay!

Overall, an amazing game, that was more than worth the money.

Only fault is it's too short.

I've never played anything like this. A new type of tower defense. Even after 2 years, I still enjoy coming back to this game every little bit and beating another Torment map. Highly 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.

Damn. This. Game.

Avoid it all costs. There is a good chance, if you were born before the 90s,
or even after, have a history of strategy games addiction and are suffering
from the almost always fatal 'just one more turn' syndrome; well, this game
may eat your soul. That what is left. As for it being real time, you'll just be
advancing your defenses one tiny bit more, just getting that one upgrade,
maybe, yeah, well, that strategic position and then, then call it a day.

You know what? From that position, the other two, just saying, be a matter
of minutes, at most. Well, that was fast, I might just set up initial positions
on the next planet, for tomorrow. Huh, when I set the alarm clock I still had
eight hours to sleep, now there are only five left? Damn it! I'm not going to
school anymore!

I won't talk about the gameplay. Things are already worse as they are now.
Don't let yourself get fooled by it's uniqueness, the well balanced challenges,
the well worked out story line or even the insane replayability.

You've still got the chance at a life! Don't waste it! I almost escaped.
But I did reinstall Creeper World. And I will be in Arc. Eternal.

Creeper World 3 is a very innovative strategy/TD game which resolves around fighting a very unique enemy using a variety of weapons, including a 4-6 hours story, two entire galaxies to conquer, random map generator and tons of insane custom maps (most of which powered by practically limitless custom programming language). I've been a huge fan and supporter of this series ever since I've found Creeper World 1 on Kongregate. The game is worth every cent and if you're a fan of non-hardcore strategy games (or a time attack player) who likes territorial expansion and variety then this is a game for you! If you're a story kind of person then I recommend starting from the first title to understand it all.

Ok the fact that I have nearly done 2000hrs on this game I think speaks for it's self. I love this game, there are so many elements to this that you can never get bored of it. I also own the first two creeper worlds which are great fun to play but this newer creeper world has gone above and beyond what I thought this game would evolve into.
