Ultima 3

The  is a TESTBED boss.

Design
is a strange boss that is structured vaguely similar to an AWP. It is made out of five separate triangles with three Guardian-colored ones clustered around a reversed green one. Behind the green one is another Guardian-colored triangle. On each of these triangles is a single centered turret. Most of them have what seems to be a plain auto turret, but the ones on either side of the central green triangle have -like turrets instead.
