Color Me ImpressedG 10

This achievement requires you to complete a level without dying, failing, restarting, or continuing on the Normal difficulty.

You must play an entire level in one sitting without stopping the session with death or checkpoint restart, etc... It doesn't matter what mission you choose to attempt this on, all of them are roughly 10-20 minutes long, and equally easy to accomplish. I would recommend, however, attempting this on the first mission, as it is both the tutorial level and intro level to the game. There are plenty of enemies, but if you manage your aim will (Enable Auto-Aim in the options menu) and use cover as often as you can, you will earn this achievement without any trouble. Most experienced FPS players will probably earn this their first try.

The achievement should pop at the end of the level you successfully completed without you having died, failed, restarted, or continued.

EDIT: Might add you need to choose start new campaign. Cannot choose a previously played checkpoint.
