SWAT: Elite Force is a massive overhaul of SWAT 4: The Stetchkov Syndicate, making it into a more realistic tactical police simulator.
After you have completed a mission (either successfully or unsuccessfully), the host will need to pick a new map. The SERVER SETUP menu is changed to CAMPAIGN in Campaign CO-OP, and it is here where you pick the settings for the next map.
You might notice that it says "Waiting for host..." in the lower right corner. This is somewhat of a new feature as well; the game will now tell all clients what the next map is, if the server is on a rotation. (For instance: "Next map: SP-Hospital")
Best feature!
okay so next question how do you play co-op with other players using the mod?
