Plutonium

Ok, these are BO2 commands so not all might work with WaW, but this should turn off some more "graphically intensive" things.

you can play coop first you need to enable UPnP from the router site for example 192.168.1.1 then add the friend who you want to play with(follow him in plutonium to add him) then on the main menu click on friends and game invite then voila you can play now
note: this is not the only way to play coop if this method not worked for you watch this video https://www.youtube.com/watch?v=oLekKkhiZk4
if hamachi didn't work you can use Radmin VPN(it's not a VPN it's only named Radmin VPN) I recommend to use Radmin VPN because it's easy and fast

sl4yer_jeff did it fix?
