Hello there.

The lobby creating system might be too confusing for other players, I would suggest you putting something like the game mode console name. Or simply editing the single player function to do something like "map mapname.bsp (gamemodename, ex: mutation1)" It would probably make everything easier and add a simple single player gamemode.

Also, regarding split-screen support, the upper part does everything. I know (maybe some people don't) know how to set up a split screen mode with controllers and all stuff. But it's kinda hard and confusing to set up one WITH an internet and it's near impossible to make one without internet. I managed to do with internet anyway. So telling us the gamemode name (ex: mutation1, mutation2, versus, realism) would REALLY help. Thanks.
