The Booster Closers have faster speeds than that of the existing Arena Closers, therefore it rushes to players like a normal booster would, but with a faster pace and kills them instantly with just a single bullet.
Booster Closers are like a normal booster tank (tier 4) but, with a bigger yellow body and bigger barrels.
The Booster Closer is one of the fastest Arena Closers in-game besides the other being HOT WHEELS, it shoots bullets with very high speeds from its front barrel and two thruster barrels that instantly kill players.
