Last one got patched, here's a new and improved one..
Won't be so buggy on d/c now, enjoy it while you can.
Credits go all to me x)
You still need the bypass for this to work, or else you will disconnect.
Hotkeys:
F9 - Turn on Unlimited Respawns
F10 - Turn off Unlimited Respawns (If you're in SnD)
F11 - Turn off Unlimited Respawns (If you're in Zombie)
F12 - Turn off Unlimited Respawns (If you're in Spy Hunt)
Open up the trainer when you're IN-GAME, and you can just leave it open the whole time. You don't need to ALT+TAB to use hotkeys now.
