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.

Okay! Time for another review. This time: Creeper World 3. I'll just start right out by saying that I freaking love this one (and also that I've played it for more hours than it shown here... I hate pointing that out, but people get all weird about it).

Creeper World 3 is, at it's heart, a tower defense game. The absolute most basic concept of placing towers or turrets to defend against an advancing foe is here. And of course you have energy and such to manage. But that's about where the similarities to normal TD games end.

The heart of CW3's genius is the enemy you face, simply known as Creeper, or Creep, whichever. Instead of lots of seperate enemy units running at you in lanes (which ALWAYS seemed so freaking stupid to me in other TD games) the Creeper is a sort of... blue/purple goo. EVIL goo. This stuff spreads pretty much like you'd expect a liquid to, and the game renders/simulates/whatever this liquid really, really well, over a landscape that consists of varying levels of elevation (or sometimes, blank void areas that nothing can flow into or land on). Your main targets in most maps are Emitters... big spiky blue things that are the source of the unending slime. They just keep pumping it out, non-stop. Since the Creep is pretty just a mindless liquid, it's behavior is very predictible.... but the fact that it's a liquid means that it can flow pretty much anywhere. This is not a foe that's restricted to pre-set lanes. And remember, this stuff JUST KEEPS COMING. Sure, maybe a deep gorge might hold it for awhile.... but as it keeps pouring into that, eventually, it'll overflow. It can get anywhere, eventually.

Fortunately though, breaking the norms yet again, you also have the ability to work anywhere on the map. Your towers are not restricted to specific spots like in most games, and this is the other half of the brilliance of the game. If there's available space, you can build something there. And most of the things you can build are actually pretty darn small... you can fit TONS of things around, which you'll be doing.

Just dropping towers isnt enough though. Like I said, the Creeper NEVER STOPS COMING. As long as emitters exist, they'll keep making more. They'll never stop until you destroy them. So you cant just hold a defensive line forever. And this is why, unlike other games, you're actually expected to ADVANCE, taking more and more territory for yourself, and reaching and destroying each emitter or other major enemy structure. To accomplish this, your turrets can fly. You can uproot them at any time, and give them orders to move to any other spot where there is room. It's simple, and you'll find yourself doing it really, really often. It's a major part of the game, and has alot of possible uses.

Of course, you have your limitations. You only have so much energy to go around, and this energy is generated by your "network", made up of collectors (pull in energy from the surrounding landscape), reactors, and relays, among other things. Collectors and relays create lines between them; energy and other resources can flow along this spiderweb of nodes, usually in the form of little colored spheres or blocks. For the most part you really only use energy when something is requesting it; when building a new object, or when an old object needs a refill on energy/ammo/ore/whatever. So your energy usage will leap up and down depending on what you're doing... dealing with it isnt simple as your network grows into more and more of a hideous tangled mess.

And there's so much more than just that... the network is complicated enough, but the game has tons.... and tons.... of different mechanics and turrets and gizmos to use or deal with. There are things like Strafers, which arent turrets at all but are planes that launch from pads you build, which will go off and perform strafing runs against the goo in whatever area you tell them to. Not everything is a tower. That fact adds even MORE complexity. On the other side of things, not every threat is the Creeper itself. Early on you'll be introduced to Spore Towers, for instance... nasty structures that sit there for awhile charging, before letting off this huge blob through the sky towards your structures. Or a variety of other things that exist to assist the goo and make your job so much more difficult.

The good thing is, the game does a really excellent job of easing you into all of these different concepts. The campaign is very good at teaching you. However, one way or another the complexity is very high here. Be prepared for a complex challenge.... but that's what you want, isnt it, from a strategy game?

The best part though is that this game has incredible replay value. After you're done with the campaign, there's all sorts of other stuff to do. Including downloading and playing maps made by other players, or using the random map generator (which in itself is very highly customizable, so you get the sort of map you're looking for) to create new challenges for you on demand. I've seen plenty of players get hundreds of hours out of this game... the replayability absolutely is backed up by the game's incredible depth and potential for challenge, and is something you can just keep coming back to.

And one other thing I'd like to point out, and this is possibly the best part for me: This is a very ACTIVE game. Alot of TD games have you sitting around waiting for stuff. But this? No. There's always something for you to DO. When you're not setting up defenses, you're pushing forward. When you're not dealing with your towers, you're expanding your network, or perhaps changing Strafer/Bomber routes, or dealing with an unexpected breach in your defenses, or perhaps using your terraformers to deform the terrain or build walls (yep, you can do that in this).... and all sorts of other things. If you ARE finding yourself in a dull moment, typically it means there's stuff you COULD be doing... you just arent. And that can come back to bite you pretty hard, so you want to make sure you're always aware of your options at all times. Really though, the game's flow/pace is superb. Always something happening and always something to do.... no moments of sitting there and waiting. Oh, and you can speed up time, too, if you want. I never really do that myself though. And there's a ton of approaches to every situation. Your playstyle is up to you... the game generally doesnt force you into specific approaches.

Oh, and a word about the graphics: They're fantastic. This is a colorful, VIBRANT game, where everything stands out, yet is very easy to differentiate. It's super easy to see what everything is at a glance. Overall I really just freaking love the way this game looks.

Overall, I really cant recommend this game enough. This is a brilliant strategy game that breaks so many of the usual rules of TD games, replacing the broken bits with new bits that are so much more awesome and fun than the old bits. If you love strategy games of any type, if you love a challenge, and if you want some real, major replay value, something you can constantly come back to.... you'll find it here. I cant recommend this enough.

Just... try not to move your towers directly ONTO the goo. That's just embarrassing.

I love this game. Have completed it multiple times and enjoy it each time.
I also love the soundtrack. VERY ADDICTIVE and each level not that long so I never feel like I am spending as much time on it as I am...

A fun and very satisfying game. Especially when you flatten the map, wallpaper it with berthas and then just lean back. A fun story is fed in a quite relaxing manner I think, letting you ponder a bit and not scroll paragraph after paragraph. I felt like a key entity in the story rather than a hanger on which isn't a given in comparable games.

I love tower and defense type games especially the ones with high complexity. For all of Creeper World's unique building types, interesting building connections, and neat other ideas -- you're still fighting water. The story tries to turn the "purple water" into a menacing all encompassing alien blob, but it doesn't behave like one. Heck, the water moves in a really non-aggressive way like waves lapping at the shore. If you want a game with AI that adpats to your playstyle, look elsewhere.

The most stressful time in any given match is the first few minutes when you're building your base up. I've hit restart numerous times because of acting too slow (mostly since I'm watching TV at the same time); however, once you're up and running defeating creeper is not really about strategy or skills, it's more like a waiting game. You'll be slowly grinding out the time of waiting for buildings to construct or moving your buildings around. The only way this game is interesting is that it allows speed players to post their completion times for everyone to see.

While I do fawn over pixel art, Creeper World is very dated even for pixel graphics. There are loads more mobile games that look better than this. I will say that the strongest aspect of the aesthetic is the soundtrack. I never felt bored with the music and it gives this emergency type of rock background in the environment. Nontheless I turned it off so I could watch TV and youtube.

I could see myself playing a little bit more, but considering the 2 hour limit in order to get a refund, I'll rather stop now. In order to still somehow write a meaningful review I've read a lot about what others had to say (both good and bad) and watched videos online.

The problem for me is simple: Every mission is the same basic concept + you are not fighting against any sort of AI, but against some fluid goo which always spreads, you always stop, and then you grind your way forward to destroy it. It's weirdly enjoying and at the same time surprisingly non-engaging. You could play it while watching a film, especially once you have set up base. I can understand how people sink hours into it, just how some people sink hours into mindless point-and-click games, but I see no strategic depth here.

Positive Reviews actually acknowledge that to some degree, and the ones talking about any sort of "strategic depth" do a bad job explaining what exactly they mean, while the bad reviews are criticising the same thing, and some of those people have clocked considerably more hours than me.

This + looking at videos online has led me to the conclusion that these basic game mechanics don't change, sure there are buildings to unlock, and some tools you have to use in certain situations, but I can't see any possibility of strategic depth with this kind of concept.

It would get a good review for 2,49$, maybe for 4,99$ even, I could see myself playing it for a few more hours or sometimes to just waste time, but for 14,99$ I expected more. So get it while on sale, and stop before the 2 hour mark to rethink your investment. It's somewhat enjoyable, but more of a time-waster instead of an engaging game that will make you think.

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.
