trying to play mohw by myself

im tryna play this  game alongside with my laptop but i cant it always put the second player in my team how do i fix this?

MOHW by default always prioritzes a two man squad in multiplayer as part of its "Fireteam buddy" system.
The first two players that enter a server will be a two man squad for team A, the next two players that enter will be the same for team B and so on...
Use a team balancer plugin with procon, that might fix the that particular issue, i believe there's one called MULTIbalancer that worKs will all procon enabled games, assuming you own the server you're trying to play in...
