Keep It Clean
Kill 7 Moa during Winter Contingency.
An achievement carried over from the original, "Keep It Clean" tasks you with killing 7 Moa, ostrich-like bird found throughout the level that are completely harmless. They're easy enough to kill, just get in close and bash them or shoot at them. Here's an older video to show you how it's done.
Note: You will have to kill 7 Moa. There are an ostrich-like bird. There are a lot throughout the level (There are more than 7). They're easy to kill, but they are fast. Just simply kill 7 during the level and the achievement will pop. Reloading checkpoint for killing 7 at the beginning of the level won´t work. You need to kill 7 during the level.
