Improvements come to the combat as well. While the bone-breaking bits still remain the most satisfying thing about Mortal Kombat, NetherRealm Studios has taken the buddy system from Injustice 2 and added it here. The Kameo fighter system is a buddy system which allows you to break enemy combos or chain your own combos. The list of Kameo fighters includes Scorpion, Sub-Zero, Sonya Blade, Kano, Goro, Kung Lao, Stryker, Jackson “Jax” Briggs, Cyrax, Sektor, Frost, Darrius, Sareena, Motaro, and Shujinko. Some of these fighters are not part of the main roster which includes Liu Kang, Scorpion, Sub-Zero, Raiden, Kung Lao, Kitana, Mileena, Johnny Cage, Kenshi, Smoke, Rain, Li Mei, Tanya, Baraka, Geras, Reptile, Ashrah, Havik, General Shao, Sindel, Nitara, Reiko, and Shang Tsung at launch. Many of these characters are returning to the Mortal Kombat game after many years and that nostalgia will eventually grip the best MK players to grab a copy.
