secret marine and secret area
Ok first go to the level where you meet the flood at any difficulty at the start your in the pelican keep holding down the backwards button if you jump out if the ship jump back in and hold down till the plane stops at another point this should be on the cliffs of the level.
1. Get out and face the way the pelican is.
2. Walk forward till you see a corner with a hill that you can't walk up.
3. Turn right and walk forward and eventually you will see a random marine standing there.
