Early experimentation with atomic fusion yielded disappointing and potentially dangerous results. However, scientific tolerances were considerably lower in the UNN military specifications, so TriOp rushed headlong into production on these god-forsaken devices.
~ Dr. Marie Delacroix, Von Braun Chief Engineer

The TC-5 Fusion Cannon is a usable weapon in System Shock 2 and the last non-organic weapon you can find. This weapon fires a slow, powerful projectile that explodes on impact.

Requirements

The Fusion Cannon requires Heavy Weapons skill level 6 and Strength stat level 4 to use. No research is required.

Locations

There are three Fusion Cannons in the game:

  • The first one is carried by a corpse located near the Transmitter, on the Recreation Deck, and is broken
  • The second one is located on top of a piece of machinery on UNN Rickenbacker's Deck A near the broken Meson Field
  • The last one is located inside a High Security Crate next to the Resurrection Station on Rickenbacker Deck A

Ammunition Type

Prisms icon transparent.png Prisms - Crystal prisms, which are a good energy storage medium and allow the Fusion Cannon to operate.

Firing Modes

  • Normal Mode - It fires a slow projectile when the trigger is pulled.
  • Death Mode - It fires a even slower projectile when the trigger is pulled, but deals significantly more damage.

Modifications

  • Level 1 - Increases battery size from 40 to 80 and increases damage to 110% of normal.
  • Level 2 - Reduces ammunition use by 50% and increases damage to 125% of normal.

Strategies

  • Due to the slow projectile speed this weapon should only be used on slow/stationary foes, such as Turrets and droids.
  • DEATH mode inflicts more damage and has a larger blast radius but doesn't use any extra amount of ammunition. Arguably, it should be used as the default firing mode.
  • Although it's a level 6 weapon, the Grenade Launcher can deal a lot more damage. This is partly due to the fact that level 6 weapons do not receive any bonus damage from combat skills.
    • The Fusion Cannon can only deal 100% more damage to fully mechanical opponents, while EMP Grenades can deal 300% more damage to them. Moreover, the Grenade Launcher has different types of ammo to handle different types of enemies.
  • Prisms are commonly found later in the game and are very inexpensive to purchase. In fact, only standard bullets are cheaper than prisms.
  • In later parts of the game, the Fusion Cannon can by used by Heavy Weapons specialists as a replacement for the Pistol to eliminate Security Cameras and Grubs.
  • The Fusion Cannon can seriously hurt you when used at close range. It's best to use another weapon when fighting these enemies.
  • This weapon shares its ammo with the Stasis Field Generator. It's usually best to choose one or the other as your secondary weapon.

Trivia

  • This weapon is marked with the number 397 on its chassis, along with indecipherable letters below.
  • TC-5 Fusion Cannon was most likely designed by TetraCorp, even if it's produced by TriOptimum.
