Halo 4 Achievements Revealed

343 Industries has released a list of Halo 4 Achievements you'll need to unlock to boost your Gamerscore.

------SPOILER ALERT------

The list includes references to new characters, enemies, and plot.

"Our primary goal when creating Halo 4's achievements was to reward milestones and increase replay value while balancing both difficulty and the breadth of game modes," the studio said.

"Our secondary goal was to live up to Halo tradition with weird ass names for some of them (hello, The Dongblainer!). While you will only be able to speculate on the exact nature of some of these achievements, here's a peek at their very basic in-game descriptions."
Needless to say, you should avert your eyes now if you want to avoid spoilers:
