Infested Planet is a real-time strategy game about directing a small squad through an overwhelming alien assault. Its premise puts five elite soldiers against a vast horde, with a perimeter under pressure and the safety of a base in doubt. The challenge is not simply to hold ground: players must decide when to retreat, where to rebuild defenses, and how to create an opening against the enemy.
The tactical choices include equipping soldiers with weapons such as flamethrowers and laser guns, constructing defenses and siege support, and sending forces to attack alien hives. Enemy mutations change the demands of battle; a weapon that works against one form may prove ineffective when the aliens develop bullet-proof armor. The game’s listed arsenal and buildings, alongside dozens of alien mutations, support this cycle of adapting and choosing new tactics.
A lengthy campaign provides a single-player framework for developing weapons, while procedural maps and random mutations add variation to encounters. Its appeal instead rests on managing a vulnerable squad, adjusting to changing threats, and pushing back against large enemy forces.
