Well the first glitch I mentioned I found with a friend, nobody told us the glitch, we found it on our own.
A friend of mine found the 2nd one.
Scarab gun is something you'll have to look up on gamefaqs.com or something because it's too hard to explain how to get it. Basically, it's the same gun that the big ass spider on metropolis has, and it has infinite ammo.
