The game has a vacuum like controller with two buttons; one for the light and one for the vacuum. Shaking the controller sucks in the ghosts. The console also has a bomb button for both players.
The game was first spotted in November 2014 where Capcom did surprise location tests.
SEGA (owner of the facility which the location testing was occurring) then released screenshots on January 31, 2015 showing the first actual screenshots as the second location tests started.
