Dead End in the Monster Pit (Metro: Last Light)

hello everyone ... tell me please ... I'm at a dead end ... I reached a pit with a big monster ... and I can't find a way out ... I seem to hit him, I spent almost all the cartridges ... and he is lying around without moving not dead and not alive ... using a compass I'm trying to find a way out, but everything is in the thickets and there is no way out ... who passed, tell me ...
