The BlazBlue: Calamity Trigger HDD and USB are the game component’s needed to play the traditional 2D fighting game developed by Arc System Works in 2008 in an arcade machine.
The game is a 1vs1, duel style game based on rounds (called a "rebel") and one match can consist of one to five "rebels". To win a round, one player must knock their opponent's health to zero or by having more remaining health than their opponent after the clock runs out.
Every character has a weak, medium and strong attack, as well as a "unique" technique, called a Drive attack, which is different for each character. Those attacks are also known as "A", "B", "C" and "D", and can be used to create various combos. A combo consists of two or more consecutive attacks that hit an opponent. Players can also performs grabs by pressing the "B" and "C" buttons at the same time and can block using a regular block or Barrier Block by holding “A” and “B” at the same time.
Some attacks will use portions of the player's heat gauge at the bottom of the screen. The heat gauge is filled by either dealing or receiving damage. When a character has 50% or more heat, special moves called "Distortion Drives" can be performed. When a Distortion Drive is successfully performed, it deals massive damage.
