Defiance on PS3 - Weapon Mod Trailer

This video highlights the Infector (not only does damage but grows boils on your enemies that erupt with monsters that can then wreak havoc on other enemies), the Bio Magnetic Gun (does damage to bad guys, heals the shield of good guys), the Rocket Launcher (come on, who doesn't love those), and the Detonator (think Rocket Launcher on speed with the ability to bog down enemies so those you don't finish off are vulnerable for the one-two punch).
