Red Faction: Armageddon Infestation

Infestation is a co-op multiplayer mode that can be played either in solo offline or multiplayer LAN or Online modes.

During Infestation, the objective is to fend off wave after wave of attacking aliens. In some situations all you have to do is survive, in others you must defend structures and equipment from the aliens and maintain their integrity.

The mode is equally subjected to the same difficulty tiers as the main game, allowing you to change between Casual, Normal, Hard and Insane.

Alongside this, you can also purchase upgrades from the main menu, allowing you to enhance your combat abilities amongst other upgrades.
