The story goes on from Quake 2 and this game takes ideas from Halo, Starship troopers and Half-Life and it does not go that well. You play another space marine this time and you have to fight of new Makron that they Strogg has created. Mostly I found the gameplay tiresome and I hate games that have a 'jump past three traps in a row' section. There is a part in the story when the player get put inside a machine to turn him in a Strogg and it was fun to see but it was not used well by the story.
