I went to Venus for missions and where all of the Vex gates are, there are Wolves. The big guy with the rockets is immune to everything and the little dudes all say "resist" no matter what I hit them with, even rockets. What a croc of ****. This is why I stopped playing for 5 months, game sucks. I am level 24 and it still only gives me gear and weapons for like Level 10. LAME. Back to Halo, less bugs.
