Ok so we know ammo,exp,credits,hp/mp is server sided. Speed hack is not working (works for some players but max at 2.5 more speed crashes game)
But did some one tried to decode game files, this game runs on Peer 2 Peer connections like if i create a mission iam the host so in game files should be host params some where same like in Vindictus or Call of Duty u can attach DLL injectors and open like console to play with host strings, maybe that way would be possible to lets say disable AI (for boss farming) or jump heights etc etc.
