ET Comic Mod
r_fullscreen 0, host server, run et.exe again and join to ur localhost… then use alt+tab to switch between windows.
this can all be done with omnibot scripting. it is fairly simple to script the bots to go stand in a specific location and perform some action like face a specific direction, fire a weapon, use voice chats, say something, etc. you can also give them user input commands (crouch, prone, jump, etc) to possibly put together some sequence of actions. it is also possible to synch multiple bots actions if the threads were blocked until some signal (voice chat from player, time, etc).
however, it would probably be easiest to just get some volunteers to join your server.
I posted a script somewhere (not made by me). It had very cool controls with numpad, where you could change angles and zoom
