Killer instinct is a fighter that showed up during the huge flare up of fighting games. It is similar to mortal Kombat in a few ways but executed differently in others. Both games revolve around special moves and combos. Killer instinct focuses on the combos more then anything, with an announcer who will announced your combo based on how long it lasts. I.e 3 hits is a super combo and 29 is an ultra combo. The game has a learning curve that all fighters demand but with practice and patience you can get the hang of it
