Roadkill Achievement

During Mission 5: Red Star Rising, you will need to kill a total of 5 enemies using the Buggy. Progress will save when you reach a checkpoint, so keep in mind that if you die, your progress from your current life will be lost. You'll come to a part where you descend down a tower, then some rocks to a buggy. At this point, you'll want to get in and focus your fire on the helicopter to take it down first, as it will be the most troublesome. Next, you'll want to get out of the buggy, and mark the enemies that are located at the top of the structure in the middle of this section. There should be a total of 4 enemies which you should run over, then change your buggy if it is damaged and trigger the next checkpoint. Then you'll come to the section with the HUGE gate blocking your progress. To the left of the gate entrance there will be some CELL soldier enemies that you can run over to finalize the achievement. If you still haven't attained the achievement, progress through the gate, and you should find 1 more solider enemy near the middle of the road on your way to the final base.
