Brutalities were only on the SNES and Genesis versions of the game, Noob isn't playable in arcade (but fightable), and Rain only appears in the watch mode video. Animalities can be done in arcade UMK3, but not the SNES and Genesis versions.

Thankx and how many revision release on MAME and which revision is best and can we fight with Rain

Revision 1.0, 1.1 and 1.2 are available, 1.2 is the version of choice. There is a hack to allow you to play as Noob Saibot with Kano's combos and no special moves, and you can also select Human Smoke at the selection screen. The only time this would be beneficial is during 2 on 2 matches so you can have 2 Human Smokes. This version sacrifices Shang Tsung and Stryker in order to select them. It also still does not have the hidden characters immediately selectable. There is a cheat code made by Moe30W in which both players must enable the hiddens by toggling a cheat option, and then P1 resets the game and they are unlocked. You will have to obtain these versions on your own.

Thankx can you tell me where cani download UMK3 Arcade original Roms
