Super Ultra Lag!

[FroggeReborn]

Ok so heres what happened, i was trying to find a game of Bombing Run which the mode is hardly played with anymore, but i luckly found one in Black Market Server, when into the room got my weapons i needed and pushed f5, When i got into the game the Map was gone, like i could see through everything, Everyones Character was Ultra - Sized like a cheat code u can activate in fucking Mario games, my Gun was in shape on a Zombie Hand and When i got killed in said i Infected Myself.....and i wasnt using any hacks cuz im a legit player but anyone know wdf is up with my game, i even tried re-installing and the same problem keeps happening no matter what map or game mode i try and play on. At first i thought it was really really bad lag but then its not, Please help
