Numerous defenses were installed on the grand outpost's walls, such as the improved gatling gun with bigger calibers, and a new experimental Rift-Powered Beam Shooter that could only be manned by the second gen usalians, where they could connect through the psycast formation within this 5 meters length railgun-esque canon and channel their rift-apparition into a special energy container. The user can then unleash the accumulated rift-energy into a laser-like projectile.
This experimental weapon had been tested to be capable of drilling a hole into numerous types of steel alloys with great ease, even with them being reinforced with spiritual telekinesis.
