Kill a Crusher without it damaging you
Towards the end of mission 9 (Hope in Hadley's) there is a fight with a crusher. Once it appears, find high ground to avoid damage from it. Kill using your explosives and shooting the body. You must get the kill for this to count. Use restart checkpoint to your advantage if you're damaged by it or don't get the kill. Can also be done in a multiplayer game.
