■Mobile Suit Features
・General unit with cost of 700.
・A compact melee-oriented MS developed under the Formula Project
as a return to the fundamentals of battlefield tactics.
・As 5th-generation MS production costs rose,
the Federation’s Strategic Naval Research Institute (S.N.R.I.) started the Formula Project
to re-envision mobile suits with their original design as versatile humanoid war machines in mind.
・Stripped of superfluous integrated weapons systems,
this minimalist MS uses micro-honeycomb technology to slim down the armor and movable frame,
reducing size and weight to put the “mobile” back in “mobile suit”.
In addition, it boasts 1.5 times the output of conventional MS thanks to two miniaturized generators.
・It also features mission pack system hard points for increased versatility.
A holo-cube processor is used for complex controls,
and some even speculate that it has an artificial personality processing system on board.
・Can be deployed both on the Ground and in Space.
