Since Sven Co-op is heavily based on the original Half-Life, it is essential that the player is at least familiar with Half-Life and its controls, and it is recommended that they have completed Half-Life's Hazard Course tutorial level. The current version of Sven Coop being worked on is 4.5. It has since grown to become a full blown mod, with a full team, and one of the most played games on Steam as of September 18, 2006, excluding the official games by Valve.
Sven Co-op was released on Janubefore Valve's Team Fortress Classic - and is therefore the oldest Half-Life mod in existence that is still in development. The game was originally created and released by Daniel 'Sven Viking' Fearon as a small mod with two single player maps and the game configured to allow NPCs in the game (by changing a CVAR to allow them to exist in the multiplayer game mode).
Sven Coop (usually abbreviated as SC) is a cooperative game multiplayer modification for the first-person shooter computer game Half-Life, where players must work together against AI controlled enemies (NPCs), solve puzzles and complete other objectives (usually specified in a MOTD) as a team.
