The car glitch was patched long ago.
Ice speed glitch doesn't really help much:/ just that you can use other guns while sliding but it'll wear off when you move or get damaged.
Car to building isn't really an actual offense to the game lol...
Amazon has some issues atm, not sure if it'll be fixed any time soon.
The reload glitch is really annoying, but not sure HOW would it be prevented.
The summoning thing is false lol. You can't summon your buddy into a room that's restricted to him/her IF you're allowed to go in. I've tried long ago.
Thought you said this was suppose to be glitches? Minigun is one apparently ._.?
