Plutonium

Hey there, so I was trying to enable sv_cheats in a solo match so I can have some fun, (give myself all the weapons, god mode myself, noclip around the map n such) but I do not know how to enable them. Any help would be appreciated!

So I've been trying to launch BO2 plutonium using t6zm.exe, I've downloaded t6r.dll, and it is in the right folder location. Example: C:/Games/t6_pluto_full_game But still, when starting t6zm.exe up, it still shows "Failed to load libcef."
