First of all, this is the Seventh Anniversary Edition (7AE, or simply AE), which is a patch for the regular Oni. This patch has some effects, namely
- all special moves are unlocked straight from the beginning
- enemies have more endurance and generally behave smarter
- enemies now run for cover when being shot at
Also, the other mods that I'm running on this, are the modified throws and attacks. Most notable of these is the extended range of Mai's Crescent Moon Kick, and Muro's kick special.
