BlazBlue: Calamity Trigger by Aksys Games is a 2D one-on-one fighting game, which features an original cast (including many weapon fighters) and uses a four-button control scheme (weak, medium and strong attacks plus an EX button which makes your character perform unique special attacks). The fighting system is based around the ability continue combos when opponents are in a down state. On the defensive side, you'll have a number of ways of getting back up when down, so combo attacks don't pummel you. BlazeBlue employs the Type X2 arcade board and mixes 3D characters and 3D backdrops.
