The game focuses on the troops of Delta Squad as they fight to save the human inhabitants of the fictional planet Sera from a relentless subterranean enemy known as the Locust Horde. The player assumes the role of Marcus Fenix, a former prisoner and war-hardened soldier. The game is based on the use of cover and strategic fire for the player to advance through the scenarios; a second player can play cooperatively through the main campaign to assist. The game also features several online multiplayer game modes for up to eight players.
I really was not into these games that you see in 3rd person view I think they call it. Anyway a mate in the USA had it and he raved about it and we were looking for a game to play co op together so I purchased it. This was the last PC version released and I really got into it and were were both disappointed that no other PC versions were released of it.
