Yes, it's a footage coming from a 'demonstration' laser disc (also VHS) released back in the days to the public. On that 'demonstration LD' footage you can see the entire game played by 4 players. Yes, it's a single mission (but can switched to an other one 'Attack Of The Zolgear', with the need of specific roms / LD).
No need a long game, the main purpose of the 'experience' is competition against other players in the same game (like a race in Daytona USA for example), or 'time attack/best score' against the world!
Soon UGSF Europe vs UGSF Japan!
