Joseph is the strongest character in multi-player mode. When playing as Joseph use the Shredder upgrade to the shotgun. It will kill an enemy in two to three hits.

To properly use the Vampire gun, get very close to an enemy, then hold the trigger. If the Vampire gun hits, you will see a splash of blood. Continue to hold the trigger and your enemy will begin to wiggle and scream. While this is happening, the Vampire gun is sucking out their blood, making them shrink. This in turn gives you health. However, the tougher the enemy, the longer it takes to fully drain them. This can leave you wide open for attack, rendering what health you obtained useless. Make sure no other enemies are around when you use it.

After every chapter, under cheats (secrets) you can select a previous chapter/Boss. You will also get any items, weapons, or weapon upgrades found in the chapter(s) before it.

Beat the game twice with out cheats I figured it out by myself.
