ООО ♥♥♥ сасный драбаш

You can download old version from serioussite,if you had trouble with this,tell me.

i deleted this because it didnt match the arms of serious sam so it looked werid

I guess this is problem of workshop,other subscribition can break models...I fixed this only when i deleted all subscribes and replace weapon model with using archive(ALL02.Gro/models/weapons) for correct working replace weapon model manually,find my subscribition in game directory,open it, there wiil be *models,then open ALL02 and place *models from my subscribition into ALL02 (with replace) then will work,i don,t know what happen with workshop but i had this problem too and i think this is only way to fix this,And make sure you not subscribed any other addon where was single shotgun replacement...

Seen only barrel? From standard shotgun?

Hey,i have a problem with it.when i see the single shotgun it's not the shotgun
