Yep, you read right. Completely ABUSABLE glitches disdcovered by me, a while back but i decided i'd make videos of em anyway.

The glitches include (almost) infinite exp from zombies, particularly thugs, and item duplication. Yes you can duplicate craftable items (not weapons) as long as you have it, and a friend. This includes WINE and DIAMONDS. We all love our diamonds right? Will post it when the friend i discovered this stuff with is online.
