1on1 is a unique mod featuring small map sizes and close quarters gameplay, unique weapons inside kits such as Rocket Propelled C4 and Fire grenades. Play Co-op with your friends: we have full bot support!
A couple of modifications made to this menu to support 1on1 and singleplayer, bit of a task considering sandbox didn't have singleplayer.
Does include the sandbox-style map background
:S dodgy create button. I think it uses one of the Helvetica fonts.
Probably Helvetica Neue LT Com - 25 Ultra Light
Glad to see you used my suggestion: Using the sbx menu. Looks good!
