Dong Dong Never Die - A Shuang, Battle Royale Fights (1.6)

In this video, I was playing as the game called Dong Dong Never Die (a Chinese indie fighting game made in 2009) as A Shuang. This is just the 3 Battle Royale fights and the special battle. In version 1.02 of the game (or at least before 1.6), these 3 battles were Endurance pitting you in 1v2, 1v4, and 1v7 battles. In 1.6, it changed to Battle Royale where all opponents can also hurt each other (the round is over if you lose though) and you win if you are the last one standing. This makes it much easier in general. However, you still need to be careful of opponents that could still hurt you with multi-targeting special moves / throws / super moves (for example, Yin Yin and Jian Ci Long's super and special throws, Dong Dong's Demon Rage super, A Shuang's Lightning super move, etc).
Dong Dong, Terminator, and Violent Dong Dong all have a special battle (after the Battle Royale fights) pitting Dong Dong + Terminator vs 4+1 Bio Mans (with the normal Bio Man AI).
If you manage to beat all 3 bonus fights (and special battles if you play as Dong Dong, Terminator, or Violent Dong Dong), you get a preview of a Streets of Rage 4 game that was being shown off. I think there are some problems with the game code as sometimes you don't need to drain off the life bars of ALL opponents before the game declares you the winner. It might be related to the number of hits achieved / KOs you received at a time.

I managed to beat the Battle Royale fights.

This was played on version 1.6 of the game.
