One thing I forgot. When I attack the assassin, it seems only my weak blaster attack is the one that does damage. Whenever I use the other abilities, such as Unload, Death From Above, and the other missile attacks, he still has full health. He only has 1600 or so HP, so if I could do some damage I could easily get him out of the way. Is this a glitch? If so, what can I do?
