There's actually a whole Infinity Playlists, and things are pretty changed up. It's the only playlist that allows for custom loadouts, specializations, tactical packages and armor mods as well as personal weapon drops and killcams.

Btw, what "perk" is dropped every 30 seconds? You mean a random power weapon drops?
