The Burst Action depends on a certain part, making many previous EX-Acts from the first game into these. If a special mode is active while Awakening is in effect, then the aura will be overridden and the theme song corresponding to that mode's source material will play over the current BGM. Players can also now ride support vehicles such as the Mega Rider and Base Jabber to quickly skim across the battlefield and even man stationed turrets like beam cannons and chainguns. These weapons have excellent breaking power, making them perfect for farming parts. Perfect Grade bosses make a return though this time they can now grab players and take body damage over time. The random star-based system has been replaced in favor of a level up system that lets you upgrade parts by spending money and using materials, rather than having to farm for high quality parts.
