There is a risk of VAC/TAC bans so be careful!
The scripts in the cheat table will work online but you must be the session host. All scripts will work for every player connected to the game as far as I know, as tested in custom games. Remember the risk of a ban is higher when using in an actual multiplayer game where VAC/TAC is most likely active.
This cheat table includes the following for MultiPlayer and custom games:
[+] Infinite Ammo
[+] Infinite Grenades
[+] Infinite Health
[+] Infinite Thruster/Jetpack
Features that are being worked on:
[-] Weapon Changer
[-] Offline Zombie/MP (Maybe due to there being an injector already)
Not sure if it is important for this to have a virus scan because of openly viewable scripts. It's also a CT, so it can't do anything when you actually launch it unless you attach it to a process.[/LEFT]
