The prototype of the Adonis Colossus stood silently in the workshop attached to the LMC's spaceborn testing grounds.
Due to the sandman fleet that continued to play hide and seek with the Light Hounds, it wasn't entirely safe to test mechs in space.
This was because the testing ground in space was situated right besides an asteroid belt!
With too many Living Sentinels diverted to the frontlines and the system defense force, there weren't enough mechs to protect this facility.
For this reason, the prototype testing had to take place on land and in closer orbit of the planet. While this was a little inconvenient, the Adonis Colossus was not a difficult mech to test.
Some of the most difficult and nuanced aspects of a mech was its mobility. It took a lot of complicated props to adequately test a mech's mobility, especially under fire.
