Protodude and
Heat Man have tracked down this month's CoroCoro, and with it comes news on EXE OSS.
The most eye-catching feature is obvious: players can control Subaru as Rockman and play as him as well, though other details on this aren't clear yet. Misora can also be seen as Harp Note in one scan.
The scans show that the game uses EXE1's graphical style, while adding maps to the internet.
The scans also reveal that among the new characters is "Clock Man", presumably the Navi version of boss contest winner Clock Genius, who hails from RnR's time period.
