BlazBlue: Calamity Trigger is a fighting game developed by Arc System Works in 2008 and is the first game in the BlazBlue series. The game was originally developed for Japanese arcades and later received console and PC ports. The game is a traditional 2D fighter where two characters participate in a duel. Every character has a weak, medium and strong attack, as well as an "unique" technique, called a Drive attack, which is different for each character. Various combos can be performed by every character through careful input of regular and Drive attacks.
