O Cristo Redentor

O Cristo Redentor is a Special Ops mission in Call of Duty: Modern Warfare 2. It is based on the level Takedown and your objective is to kill all of your enemies without harming civilians. 

Gameplay
You start off the level with an M4 Grenadier in a Rio village that's not too big (about the size of Vacant). Your objective is to kill all of the enemies in the village without harming any civilians, so watch your fire. The amount of enemies you face depends on the level's difficulty: On Normal, you need to kill 30 enemies and you can only kill up to six civilians. On Hardened, you have to kill 40 hostiles (with Dogs thrown into the mix) but you can only kill up to four civilians. In Veteran, you have to kill 50 enemies (and their Dogs) but you can only kill three civilians. Plus, if you get hurt you will be put into Last Stand, but this time you can also crawl around so that your buddy can revive you in a safer area before you bleed out.
