This third person shooter has you and three comrades killing aliens to get your other comrade back alive and take the Nogari Corporation. The game is coming to Xbox Live Arcade, Playstation Network, PC and Mac this summer.
Each character has their own motivations for doing the mission via detailed flashbacks which developer of the game Tragnarion says will influence the story greatly.
The game is a part of Microsoft's annual Summer of Arcade and if the game is popular and fleshed out enough, it could get the promotion of a game disc release.
