Walls and barriers
You cannot hide behind walls or barriers in first person view unless you plan on staying at that location for awhile. Unlike third person view where you can just tap Y to automatically hide, you must hold in first person view to hide. Press to look over a barrier or to open fire. Press or (depending on how you are positioned) to look out.

Sluggish controls
If you are carrying a large automatic weapon, the controls will feel sluggish because of the weight of the gun. However, if you switch to a hand held gun, the controls will be more responsive.

Falcon weapon
Destroy 100 helicopters in multi-player mode.

Sniper rifle
Get over 500 total head shots in multi-player mode.
