"Alex Vostrov has created the most fiendishly clever, creatively generous, and cinematically thrilling facing-down-the-alien-hordes real time strategy game this side of the original Starcraft! Who says a great RTS has to be a big budget studio endeavor?"
--Tom Chick, Quarter To Three

"Infested Planet is a game I’m excited to see evolve, as it has the potential to be a unique and engaging RTS unlike any I have played before."
--Nightmare Mode

"Infested Planet is already quite fun, and the current beta is being very actively expanded, refined and tuned. If you’re into strategy, this might well be worth keeping an eye on. After all, who knows what it could mutate into?" --DIY Gamer

"The mutations are an ingenious way to mix each game up and keep the experience fresh."

About This Game

Command a team of 5 elite soldiers against an alien horde of 100,000. Surrounded on all sides, you must outmaneuver and outsmart the enemy.

The enemy is closing in around you. Your soldiers are being flanked and the perimeter is slowly collapsing under a vicious alien assault. Robotic turrets will not last much longer. Just a little more and the bugs will swarm into your unprotected base. What are your orders?

You order your soldiers to fall back to a defensive chokepoint and rebuild your defenses. Sacrifice the forward squads to gain some extra time. Gather your team while equipping them with flamethrowers and laser guns. Start building a siege cannon for fire support. Then, while the aliens are busy, flank their main hives to destroy and capture them.

You have just pulled off a tactical victory - but there's no time to rest.

The aliens are constantly mutating. One moment your shotguns are ripping through the horde, the next the aliens grow hard, bullet-proof armour. You must adapt as well. Equip your team with stealth suits, miniguns, grenade launchers - your commands will decide the battle's outcome.


  • Real time tactical combat
  • A lengthy campaign where you develop new weapons
  • Procedural maps and random mutation system keep the game fresh
  • 21 Human weapons and buildings for you to wield
  • 33 Alien mutations to keep you on your toes
  • Fight thousands of enemies at once

Infested Planet is a hectic horde RTS title that matches a handful of marines with thousands of bugs and mutated nasties, overwhelming battles will remind you of Starship Troopers' scenes where death and retreat are inescapable.

All missions start with one or more base and a team of marines, with slightly varying goals in the campaign, which ultimately require the capture of all remaining bases and/or destruction of all alien hives. Variety is lacking, but the constant tide of aliens vs your rag-tag team of marines will keep you on the edge, inching slowly towards full domination.

Sound and music are serviceable, graphics are bright and clean, albeit a bit too monotone and can make spotting your troops a bit of a challenge (especially with some overhanging cliffs textures). There is enough structures and technology to keep you engaged in random missions and skirmishes, but not enough depth of strategy to warrant investing more than a few hours after finishing the main campaign.

Good fun for tough RTS fans but implementing multiplayer with a hive faction DLC would make this a solid title! 3.5/5

You like endless swarm of swarms to shoot, burn, blow up and stuff ?
Well this game is for you.
True endless swarm, no time limit, no kill limit, no spawn limit.
Amazing balance, you'll often reach status quo with the swarm, were neither of you can advance.
The gradual difficulty, which often make the single last hive much harder than when there were 7 of them.
The diversity, you can play solely with marines, or with just one to build dozens of towers, or a mix of both.
The game might get repetitive with time, in the same way a sandbox game can become.
Very step but short learning curve. You'll loose the first few games thinking it's damn impossible, and when you finaly figure out how you wanna play, expert mode seems more like normal.
Also my best buy of the steam sales.

If Infested Planet were a kitchen utensil, it would be a whisk - success comes by flailing it about for a short period of time.

I would recommend this game to anyone who likes whisks.

On a scale of 1 - 10:

Gameplay: spatula
Graphics / Presentation: pie lifter
Story: corncob holders

Overall: good silverware place setting for 4 with two knives missing

Great strategy game! I picked this up during a steam sale dirt cheap and had a blast playing it. It reminds me of the fast paced RTS rush you'd get from the early Command and Conquer games. Base building is streamlined to the point of you deploy exactly what you want quickly, and the second you don't need that item anymore switch it out for another. Very enjoyable game. Hoping for an expansion or DLC pack in the future to expand on the game. Quite a few missions and achievements to go after, but after that you're left wanting more. Skirmish mode is fun to tinker with, and will most likely tie me over till new content arrives (which sounds like the developers are working on)

Great addition to RTS collection if one likes that genre. Command your starshiptroopers to victory against the horde.

Let me put it this way, if you are decent at RTS genre(hotkeys over mouseclicking) and you have the patience to learn few tactics to beat different kind enemies. You will enjoy this game. The game has a good way to help if you get stuck with one time use soldiers so don't be afraid of the alien hordes. Check TB's WTF is... for good gameplay preview if still on the edge.

Where on earth do I begin with this one. Right. Okay, what is it? It's not a traditional strategy game in the usual senses of the word. It's not an RTS in so much as that the forces are hideously asymetric, and it's not Turn Based either. I would call this a "Swarm control" game, where the concept is that you have a small number of deployable troops, as well as static defences, and from this you have to construct a working strategy that funnels a much larger force into killzones and crossfires.

Combat works on scales that you don't generally get to think about in such games, your 4-7 little poxy marines will end up riddling thousands, yes, thousands of enemy aliens with holes over the space of one mission, and quickly you stop viewing the enemy as a mass of individuals, but as mentioned - a swarm, one to be controlled, funnelled, and pushed back.

When you finally "click" with the concept, and you start figuring out how to approach the swarms and manage them, the game suddenly starts falling into place, systems and mechanics which were until then entirely unmanagable become second nature and intuitive, and you quickly fall into the habit of securing outposts, setting up turret crossfires, assessing where you can do the most damage, how to maximise your soldiers efficiency. You stop thinking in individual terms and if anything, approach the mission almost in a "grand strategy" way of things. That's the beauty of infested planet.

Graphics and sound are decent, it's an indie effort, and the graphics achieve what they set out to do (you won't get confused and lose track of what's going on, be thankful), ditto for the sound, the plot too, again, servicable, but the gameplay clicks, it takes a while to get over the learning curve, because the game is so radically different from what most people will be used to, but the investment eventually does pay off. The experience is very much unlike anything else around, and is definitely worth checking out if you fancy a change of pace from normal RTS experiences.
