Sven Co-op is a first-person shooter based on Half-Life, using its GoldSrc game engine. The modification enables a server to many players to cooperate among themselves and allied non-player characters in completing levels against creatures and other enemies that are controlled by the computer. The modification was initially based around the levels from Half-Life, but since have expanded to include the other Half-Life games and user-made levels. Multiple levels may be put together to make a longer campaign by the level designer. The game can also be played in single player mode, taking advances of improvements over the original Half-Life that were made by the modifications, particularly for the artificial intelligence used by non-player characters.
