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 sub's be sure and 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.
• Alternate Fire: Not applicable.
• Pros: Very immersive and generally very fun to pilot. Torpedoes cause extensive damage to the environment and subs explode beautifully. Heat seeking torpedoes negate the purpose for auto-aim in the PS2 version.
• Cons: Torpedoes explode upon impacting the surface of the water, so it's impossible to shoot one at the surface and have it sail uncontrollably like a grenade once it reaches the air. Your sub can be torn apart pretty easily by enemy subs if you let their torpedoes hit you. It's impossible to beach the vehicle, which would have been pretty cool for trying to hit land locked enemies.
• Recommendation: Enjoy, enjoy. Just make sure you master its advanced maneuvering functions if you want to survive an engagement with enemy subs.
