If you think looking at a character select screen for a fighter is a spoiler, move right along. If you'd like to see what looks like the final roster for the upcoming Mortal Kombat reboot, though, please continue!
There is of course no way to verify the select screen at this time. If you're working on the assumption that it is real, though, or even if you only want it to be real, here are the characters listed as they appear in the image above:
Scorpion - Liu Kang - Kung Lao - Sub-Zero
Sindel - Ermac - Reptile - Kitana
Johnny Cage - Jade - Mileena - Nightwolf
Cyrax - Noob Saibot - Smoke - Sektor
Sonya - Jax - Kano - Stryker
Shang Tsung - Baraka - Kabal - Raiden
Extras/DLC - Sheeva - Quan Chi - Extras/DLC
Presumably one of those "Extras" spots is where Kratos, who is exclusive to the PS3 version of the game, will end up.
