lolz its pretty good using chams. I personally dont go for the intels i like killing the spy. For like Snow Valley u let the super spy kill every1 then u w8 till he goes to the intel....... throw 2 nades and machine gun him till he die's if he sees u just go down the missle shoot then hide go behind him and stab him!!!!
Its good like in waverider you know where all the spy's are and you get massive kills i got like 35 kills and i wasn't even super spy yet then i got it and got like 45 kills and i got like 275 exp it was great
