Mortal Kombat: Armageddon (known as Mortal Kombat 7), features the best roster out of any Mortal Kombat game, simply because it’s huge, and it includes every single character from the previous 6 games! Two new characters are also introduced in MKA: Daegon & Taven (while Sareena also makes her debut on home consoles).

All the boss characters from the previous games are also available to play, which is just awesome!
