>>6090351The team of D-techs working on the new Tridents accidentally grabbed a space Powergear (budget variant) instead of a normal Powergear, so when the time came to build the limbs, they found none, shrugged, and made do with what they had.
The Space Trident uses three maneuvering thrusters instead of legs. Normally, the small size of the engines would make it woefully slow compared to the Legged Trident, however the Space Trident also uses a large fighter-grade thruster as recoil compensation for its railgun, so when not firing it can zoom around like a zero-G hockey puck.
It is cheap and fast, unlike the Legged Trident, which is cheap and agile.
