Im not sure if this is some major misprice on Grainger games part or something as the standard edition is more expensive. Also worth noting this is £90 on shopto and on the psn store and is only £5 more than the standard price from Base. I got what comes with the ultimate edition from amazon.com but i assume its the same here.
The ULTIMATE EDITION comes in a steel book case.
The ULTIMATE EDITION includes 9 additional DLC characters and 3 additional skins for Flash, Green Lantern, and Supergirl which allows players to transform select fighters into alternate characters.
The ULTIMATE EDITION also includes two exclusive gear shaders which enables players to customize the look of their roster with alternate color themes.
