Compliments of SegaSaturnSNK, we now have an extensive look at the PS4 pre-order theme for the Mega Man X Legacy Collections.
Not only does it come with a musical theme, but it also sports a home screen with X/Zero/Sigma locked in eternal combat, as well as an extra settings screen featuring support team members Alia, Layer, and Pallette. For the initiated, the former was introduced in X5 and the latter duo are from X8.
To net the theme you’ll need to pre-order both, and the scheme is live in the UK and the US currently.
