Killer Instinct was a groundbreaking fighting game for its time in numerous ways: it used 3D-rendered graphics in a more extensive and dynamic way than most games up to that time, in addition to introducing a variety of elements to the fighting genre, including automatic combos, combo breakers and the continuation of character life bars between rounds. Developed by Rare, the game was a part of a partnership between Nintendo and Midway parent WMS to create and market arcade games that would then be ported to Nintendo consoles, particularly the Nintendo 64. Despite its ties to family-friendly Nintendo, the game features a fair amount of violence and gore, including finishing moves reminiscent of the popular Mortal Kombat series. Killer Instinct dominated arcades during its time and spawned one arcade sequel and a later Xbox re-imagining, not to mention a full-length documentary.
