Ok i found a solution i was stuck under the flor of a gren building the one that u get straight inside the room from the stairs.My solution was changeing servers until there was some zombie near me and then i shoot a few shoots whit my gun and zombie came and push`d me out off the texture.

Can anyone give a respons to my problem? I`m stuck for 24h now and it`s getting frustrating because i cant do anything i cant kill myself and i`m stuck in that floor and cant play.
