- "Highly accurate electromagnetic projectile launcher with increased penetration power."
- — In-game description.
The Ballista is a unique weapon that can only be acquired via acessing the armory room in Operation D-Con. Once scanned into the player's loadout system, it will be available for use as a secondary heavy weapon.
Due to its one-shot/one kill nature and high penetration power, the Ballista is highly useful against lined-up groups of enemies, both humans and robots. Along with the P-LAW and the F-SpAr Torch, the Ballista is one of the few weapons in the campaign capable of completely gibbing human enemies.
The Ballista EM3 is available as a Payload for Phantom. It is a powerful five-shot sniper rifle, yielding an instant one-hit kill against most opponents. The weapon's iron sights form a centered outline of the target, similar to the Smart Shot optical sight.
