New Combat Moves for Konoko
The mod is available for download on Anniversary Edition mod list (look for "New Combat Moves for Konoko", package number 54000) but if for some reason you prefer to download it manually, you can DL it from Oni Mod Depot: http://mods.oni2.net/node/353
To enable Heihachi's hell sweeps, go to (your Oni folder)\AE\AEInstaller\packages\54000NewCombatMoves\oni\level0_final, and rename TRACkonoko_animations.oni to something else (e.g. add backup to the name), and then rename TRACkonoko_animationsHeihachi.oni to TRACkonoko_animations.oni.
