Recoil Cheats

At the first campaign of the last mission where you see a beach (not the first beach you see when you start), look for a surf box and shoot it. A van will come out. Shoot the van and it lay a nuke. Pick the nuke and go inside the cave (the one where you shouted the surf box). Once inside, shoot the door. Right in front of you, you will see a missile. Grab the missile.

This is a useful glitch to use for traveling. Before
you enter the VTOL, turn into a Hovertank . When you exit the
VTOL on the next level, you will look like a normal landtank,
but you will act like a Hovertank. You will be slightly faster
than the normal Hovertank, but will still have the hovering ability.
