Increase feral rage:
To increase Wolverine's feral rage, retract your claws and just punch the guard.
On Rebirth Part 2 Below Ground, when you enter where the trucks are located, there will be an electrical wire that is snapped in two. Go next to it to increase your feral rage at an extremely fast rate.
Get magnet brains without Claw Dive:
Use this trick if you cannot perform a Claw Dive in the Magneto fight. Get angry if possible, but only when he is at the super magnet platform. Keep doing this and he will soon go down. If you cannot get him there, wait on the catwalks just in front of it. Only attack when he looks frozen (or crystallized).
Best approach and attack:
When scouting for enemies use Wolverine's heightened senses. Once you have spotted an enemy, make sure you are close enough to see them clearly, but not be spotted. If you watch them for a few moments in heightened senses mode, a faint hazy figure of Wolverine will demonstrate the best approach and attack.
