Submarine

The Submarine is a vehicle in the original Red Faction.

Description
Possibly the most enjoyable and immersive vehicle in the game, the Submersible takes you deep within the underwater bodies of water that litter Mars. You'll move through canyons where air bubbles rise all around you, you'll circle underwater facilities in intense fights with enemy subs, and you'll engage Martian aquatic life. Don't worry though, the Submersible is equipped with two torpedo bays that fire off heat seeking ULT-MK1 Passive/Active Homing Torpedoes. Expect to encounter enemy subs quite often while underwater, just use the strafing and ascending/descending functions to duck behind environmental cover and just fire off a torpedo once they're in your general direction and let it do the rest.

Primary Fire
Heat seeking torpedo.
