Warhammer 40.000: Space Marine 2 is a third-person space action game.

Events take place in the distant future. Humanity has been massively attacked by an alien race. The player takes on the role of an advanced space marine and, together with other fighters of his unit, fights against the invasion. The combat system involves a combination of a sword for melee combat and firearms for remote destruction of enemies. Attacks can be parried and dodged.

You can play both in single player mode and in cooperative mode with other players.
