Double Assault Rifles
In the caverns stage, there is a box in the right corner of the room where you contact Jack Wade. If you shoot this box then a smaller one inside of it appears. Keep shooting the smaller boxes until you see two monitors. If you shoot the monitors they each give you an Assault Rifle. Now you have two AR33's, making your shooting ablity twice as powerful!
Get Back in the Vent
To get back in the vent in the Facility, stand on the toilet that is under the vent. Then hold Left C until your player ducks, then press and hold R, and left on the control stick. When your player returns to the vent, release C and R and press forward on the control stick.
This can be used in Mission Mode and in multiplayer. If you are using proximity mines in multiplayer, plant some in the vent. If someone starts up there, they won't be able to escape without being killed!
