It's Guilty Gear with fist of the north star characters
This game is based on the first half of the original manga (vol. 1-16) and uses the characters as they were depicted in the 1980's anime series. The voices of the playable characters are all performed by the original voice actors from the anime, with the exception of Kenshiro and Rei, who are both played by new actors.
Every player has a seven stars gauge that, through various attacks, can be lowered and once empty, a final "death star" will light up and the enemy player can perform a special attack that finishes of the opponent similar to the Instant Kill-moves from Guilty Gear. The biggest difference is these moves may be easily comboed into, making them far more practical then their Guilty Gear counterparts.
