Alien Swarm

You command an IAF Marine on a squad sent to clear an alien infestation from an off-world colony. The game is built around four-player, top-down cooperative missions.

Fight through alien swarms while completing objectives and supporting your team. Marine roles matter: coordinate attacks, conserve ammunition, protect teammates, and use tools such as turrets or door-welding equipment to manage threats.

Choose among four classes and eight characters, then shape your role with weapons and equipment loadouts. Gaining levels unlocks persistent items, while higher difficulty settings offer tougher missions to tackle with your squad.

Players often praise the cooperative teamwork, saying that coordinating class roles makes alien-filled missions engaging and tense, especially with friends or at higher difficulties. Reviews also appreciate the range of weapons and the mission atmosphere. Recurring reservations include the small active player base, the short campaign, and the difficulty of playing alone.
