My favorite helmet that I've used the most is definitely the Deadeye helmet. I also like the Recruit Prime, Scout, and Venator Raptor. IMO, I thought the Rogue helmet looked better in Halo 3 than it is in Halo 4. Not really a big fan of helmets with visors that take up most of the helmet. --- What did you just say? Fight me irl. Do you even lift?
I wore the Hazop for a while, the the Operator. Now I've really taken a liking to the Wetwork. Something about the pointyness and that little circle on the back, I don't know. --- They're Masterworks all, you can't go wrong.
Oceanic. I just need a giant fist attachment and then I can pose for the cover of Bioshock.
Using anything other than black makes it looks like your have crosshairs on your face. It's cool, but probably the most impractical helmet possible. --- Before all else you must build muscle. Then you must become hero to children everywhere.
