The Macromolecule Assist is a technology featured in Thunder Force VI. Its a process used by the CRAW and the CRAW Control Systems of the RVR-00/Syrinx and Rynex-R to power up the Over Weapons by obtaining energy from ORN forces.
When the player destroys an enemy or boss, it releases green particles picked automatically by the ship, filling a small gauge which is seen in the bottom left part of the screen. Once that gauge is full, the player can consume the accumulated energy using the Over Weapon.
The player can fill a total of six gauges and use three of them in a row for a fully powered up Over Weapon.
