You made a menu yet or wanna try and get in a lobby with me tonight?

surprisingly me and a friend found one lobby yesterday, but the menu is still in the process i cant seem to find any code to change the game mode to gwar or any game mode for that matter and im also kinda new to making menus although i have worked with gsc for years now but if im on when you are i will definitely try to get in a lobby with you

I'm currently on now and will be for a few hours, why not download a tool where you can change amount of players allowed into the match and just keep doing it with different game modes? I'm pretty sure there's already a tool with it

There's various RTM Tools that allow you to change the amount of players within a lobby, the only issue with that is for it to work correctly I believe you must be host. Black Ops 2 has recently switched their multiplayer servers over to Dedicated servers, it's still possible to find lobbies that you are able to force host in but the matchmaking times are usually very long depending on your Down/Up Speed.
