"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 top-down swarm management RTS developed by Rocket Bear Games. In Infested Planet you take command of a team of five elite soldiers waging war against an alien race which constantly adapts to its situation. Over the course of the campaign you must learn more about this alien race you fight in order to be more effective against it, along the way both sides of the fight receive upgrades and new toys to play with and you must adapt to accomodate these changes.

+Cool art style and good graphics
+Mostly well designed, your units, buildings, enemies etc. all look cool
+A few different soldier classes to be unlocked and used, each with strengths and weaknesses
+Several different types of enemies
+Simple yet fun gameplay which consists of just telling your units where to go. However this can at times get very repetitive, especially on longer missions
+A lot of new technologies and upgrades to be unlocked in the in-game shop
+A lot of missions in the campaign mode, many of which are randomly generated
+If you recycle a unit you get everything you spent on it back
+Enemy AI is very unpredictable which makes the game more challenging
+You can customise Skirmish maps
+Most missions allow you to approach your objectives in a way which suits your own playstyle
+Pretty interesting story
+Good sound effects

-Very steep difficulty curve, the first few story missions are easy but after that they get significantly harder, it would benefit from easing you into it a little bit more. You very quickly get swamped with enemies from everywhere, it becomes hard to go on the offense as well as defend what you've already taken
-As mentioned earlier the gameplay does get a bit repetitive
-Level environments are pretty dull and there's little variation between levels in the same location
-Apart from a couple of exceptions the missions all are pretty much just split into two types of mission, capture everything in your own time or capture everything withing a specific time


A fun top down RTS game with a cool art style, good variety of soldier classes, several different enemies to fight and lots of unlocks.

I downloaded this game since it was on sale, saw that it had overwhelmingly positive reviews and decided to give it a try. Since the game and dlc pack was so cheap I went ahead and bought the game with the dlc it provided. I have to say that this game is worth it. This is my first review here on steam and it's because this game deserves it, it deserves to be prasied because of the awesome gameplay, it's simple yet amazing visuals. This game just blows my mind. I can't get enough of it. I highly recommend that people buy it. If you're reading this review just stop and buy the game because trust me it is worth every penny.

The first time I heard about this game was from this youtuber's review and also watching his LP (Let's Play) video and I was just hooked enough to get the game.

It's a Top down strategy game where you control a few armies against swarm of aliens trying to eliminate one of their hive after the other.

Simple concept but it has a lot to offer for an indie game.

Every time you advance things get a bit tougher because of the alien mutations plus they sometimes went on a rampage at some point of the game each time you destroy one of their hives. But not only that. Since they're scattered across the map, they tend to re-capture undefended base and turn them back as hives. So there's a lot of micromanaging going on. Sure a few missions are manageable but as you progress, the game will encourage or even unleash your hidden strategic think-tank that's been cooped inside the core of your head for a long time and you don’t have a choice or else you'll lose the game.

But not to worry, perks like weapon modifications and support units (air drops, air strikes...etc) are in the game and usable on each mission. However, if you want to use them you have to earn money and to earn money you will have to win a couple of previous missions in order to advance and all that are in the game with no microtransactions required.

So this game is recommended to those who like RTS (Real Time Strategy) and/or wants to know how it feels like to get swarm by aliens with a few number of units to control like one of those bugs from Starship Troopers

"These are the rules. Everybody fights, nobody quits. If you don't do your job I'll kill you myself. Welcome to the Roughnecks!" - Rico from the movie. But in the game's case, Aliens will run you over.

Have fun!

I really should play this more often. Nothing quite like battling against swarms of alien bugs with increasingly murderous weaponry. The at times seemingly unstoppable swarms- depending on which mutations the enemy happens upon- provides very tense gameplay requiring quick decisive movements lest you be fought to a standstill and trust me, you want to be on the defensive for as little time as possible. Alien mutations will punish slow playstyles. This fine balance between hold and push has the momentum shifting constantly particularly at the higher levels/difficulties. The fast paced gameplay coupled with charming visuals means Infested Planet is a great strategy game for those looking for that quick adrenaline fix.

RTS games usually keep the scales relatively balanced when it comes to unit distribution. Infested Planet throws almost all of that out the window. While the aliens seem to have a happy society in place, it falls on your shoulders to disrupt it entirely and establish something much more pleasing to the obviously superior human eye. Thousands of aliens will march toward you in defense of their home, but we are determined to rid this completely non-sentient planet from its infestation. It’s not a genocide! It’s liberation! Moral questions aside, Infested Planet offers extremely unique strategic gameplay with thousands of enemies marching on almost every base relentlessly. Will it colonize your heart? Or is this game a plague? Let’s look closer at Infested Planet.

Infested Planet doesn’t offer a string of interlocking building or unit upgrades, and for that I am SO grateful. Instead, rewards are offered for completing missions which can be used to purchase a variety of upgrades to your units. There are grenades, to class unlocks, along with a variety of buildings which allow you to suit your ground forces to your playstyle. Are your heavy machine-gunners a bit to slow and unwieldly to hold the entire map all by themselves? Pepper in a shot-gunners and some scouts to do the legwork. As your heavies push toward the enemy bases, perhaps you will find yourself overwhelmed again. Upgrade a couple of them to flamethrowers and watch as the swarm is beat back by a wall of flame. If all else fails, build a helipad to bring in chopper-strikes and thin the horde. The options are limitless, and all equally satisfying.

Aside from picking how you want to destroy the hive during gameplay, there are also a ton of game-modes that allow you to customize HOW you want to play. One of my personal favorites features a time-limit and permadeath, which makes the impending horde that much more terrifying. The story mode features some aspects that constrict freedom of play, but I would argue that that’s what a game does. Sometimes there is a path that must be taken, the freedom still comes in the way you decide to take it. I found myself repeatedly playing missions to get the maximum amount of money possible in order to unlock the next delicious explosives-laden fruit from the tech tree. Not a necessary thing to do, but the randomized levels keep things consistently fresh.

The story in this game falls quite flat, and doesn’t attempt to touch on the bevy of moral questions. The level design doesn’t seem extremely meticulous largely due to the randomized nature, but Infested Planet has certainly earned its place in my Steam library. Very few games offer enemies this endless. Your tactics need to be tight and your responses need to be on point. I supremely enjoyed the mutations of the aliens throughout the different stages, and thanks RocketBear Games very much for the review copy. I am extremely glad Infested Planet came out of Early Access with such success. This is a game that truly needs to be experienced. As you pit your squad of marines against the ravenous hordes, you will find yourself cheering them on and even mourning their little pixelated deaths.
