Microsoft has unveiled all of the achievements for Halo 3.
In total there are 49 achievements to unlock, potentially bagging you a grand sum of 1000 Gamerpoints.
The biggest earners, unsurprisingly, come from completing the main campaign: 125 for each level of difficulty finished, plus a fair amount for passing the preceding chapters.
Online rewards will be dished out in fives and 10s, and range from running people over in the Mongoose to frying various targets with the Spartan Laser.
Halo 3 will be released for Xbox 360 on 26th September.
