Berserker Speed Glitch
Once you hit level 5 and get the Berserk action skill, you can exploit a glitch that will allow you to constantly be able to move as fast as you would if you were going berserk while still being able to use all your weapons normally. 1. Activate the Berserk skill. 2. While Brick is doing the beginning hand animation he does at the beginning of Berserk, quickly hit the Back button to get to your inventory. This will cancel the Berserk prematurely. You must hit the back button before the beginning hand animation ends or it won't have any effect at all besides just canceling out the action skill. 3. If you did it right and you exit out of the inventory, you will walk at running speed and run even faster! To return to normal, just activate the Berserk when it recharges again and wait until the hand animation is done. Once it is, just wait or exit out of Berserk by going to the inventory and it will be set back to normal.
