|To unlock this achievement, you must win 1000 rounds of combat in any mode. The most time-consuming achievement here besides finishing all characters' Story Modes on Expert.|
If you have a turbo controller, then follow this route: Go into versus mode with one round and a thirty-second timer. Rubberband the second controller so that Player 2 is moving towards Player 1. Remap one of the Strong Slash (/) buttons to , set to turbo and then tape the button down. Now, go do something else, but make sure the controllers don't turn off if they're wireless. This should take anywhere from 5-8 hours, depending on how many rounds you've won elsewhere.
If you don't have a turbo controller, as least you can have fun butchering your least favorite characters over and over in varied gory ways, right?
