There are alot of bad and good glitches. I sold a cheap weapon but got $3000 somehow, and sometimes when I shoot with the armageddon gun, the recoil hits me into the invisble boundry walls and I can't get out of them unless I teleport. But worst of all, I was just playing and then I went to the shop and sold a weapon and it said I had Nan money and it wouldn't allow me to buy anything. There is probably no way to fix this but by starting a new game.
