Among a slew of changes and additions to Project X Zone 2: Brave New World, Sigma will be joining the cast as an opponent. X and Zero are back and, according to Siliconera, they're playable from the get-go.
"And then there’s X and Zero, together from the last game but playable from what seems to be the beginning," writes Siliconera. "Their neutral move is X-Buster and Z-Saber. Their right attack is Triad Thunder and Ryuenjin, which can be followed up by their left attack, which is Frost Tower & Hadangeki. Their neutral move keeps launches an enemy horizontally, but their directional attacks send enemies straight into the air. Bandai Namco nods heavily toward Mega Man X3 here, as the pair unit gets a remixed version of the game’s introductory stage as one of their themes."
Project X Zone 2 is bound for Nintendo 3DS later this year. Head to Siliconera for more details.
