It is still quite heavy also, even though its mass is less compared to certain weapons, restricting its use to ships with lots of mass such as those in Tier 5 and Tier 6.
The Disintegrator Cannon is also Xeno Division and Cruiser only, so only the Punisher Cruiser is able to utilize it. Along with that it has a extremely high resource cost which makes it hard to mass produce on the Punisher Cruiser.
