Unfortunately, it seems we are to feel the bite of regional exclusivity once again. Japanese arcades are set to receive an interesting addition in the form of Metal Gear Arcade. Screenshots seem to resemble Metal Gear Online, which is sadly now difficult to play at all, and suggest a lightgun input. 

It seems highly unlikely that it will be ported to consoles but we can still dream. Lightgun games have been declining rapidly since the days of the PS2, with one of the only options for console gamers being Time Crisis IV. Either way, all I know is I want to play it, and I want to play it now.
