Hmmm...

I am not really sure but I don't think you can with the PS3 version... being blu-ray and all.

Your best bet is the 360 version.

Hopefully something good is found

The bloke who runs TRMK mentioned looking through it and finding little, to nothing. I think he said he found a crypt [maybe for future DLC, or an unfinished feature?], but no other character models or anything of that sort.

This is what Pat found:

- There are NO other hidden characters beyond unlocking Shao Kahn and Darkseid
- Story Mode cutscenes are all FMV, NOT in-game rendered. So those characters featured are not models available in game.
- The Krypt was planned for the game, and cut at some point
- Batman has an alternate ending featuring a mention of ERMAC
- Shao Kahn and Darkseid are setup in-game as DLC. So that's why they share that RB/R1 menu in the game. The DLC characters will go there too once downloaded to the game. So the game can for sure support it, once the characters are released.
