From Prima Games:
Before Fireteam Crimson was so rudely interrupted by the boarding and subsequent threatened nuclear annihilation of the USNC Infinity, they were deployed to the Apex mountain facility to seal off a portal network. The Covenant were cut down in great numbers during the previous engagement, but they have returned in force. It is now Fireteam Crimson’s job to finish what was started. One difference: The last time you were at Apex, you fought downhill. This time, you’re going up the mountain.
