The heavy Gauss is cumbersome, but extremely effective. It operates with 3 particle accelerators and is virtually unstoppable. The anti-proton stream is confined inside a Gallium Arsenide shell that implodes on impact releasing the anti-matter.

The Heavy Gauss is a slow but powerful cannon that deals Gauss damage. It is Gauss technology's answer to the Gas Cannon with GC-AP rounds.
The Heavy Gauss closely matches the Gas Cannon in performance, although snapshots are less accurate and aimed shots are slower. In return, it has greater stopping power and a slightly larger ammunition supply.
While a formidable weapon in its own right, the Heavy Gauss does not curry much favour amongst many X-COM players for a large number of reasons. Though they are beyond the scope of this article, the most common reason is probably the huge performance disparity of the Heavy Gauss against the Sonic weapons and its predecessor.
To its credit, the Heavy Gauss is easy and relatively cheap to manufacture and does not need exotic materials. It is a necessary stepping stone for the highly profitable craft Gauss Cannon.
Note: Gauss weapons must be manufactured
Prior to the Sonic weapons, the Heavy Gauss makes a good early-game replacement for the Gas Cannon's armour piercing role. This leaves the Gas Cannon free to work with high explosive or phosphor rounds.
