Crimson Dragon

Just what it says. reach the end of a mission 5 times. Can be the same or different missions. In multiplayer, instead of using a regenerator, you spend 20 seconds respawning. You miss any enemies or beacons during this time. So you just need to reach the end of most missions for a "D."
