I believe you can still find the Ultimate Edition on third-party websites incase it has something you want that the Legendary Edition doesn't offer. Originally posted by Sentinel Lyons:The Ultimate Edition and Legendary Edition are very similar, but have their differences. The Gods shader is included in Fighter Pack 1, so I believe you should receive it even if you buy the Legendary Edition (someone can correct me if I'm wrong.) It is known for a fact however that the only way to get the Demons shader is to purchase the Ultimate Edition. Also, Brainiac can be acquired for free by beating the story mode.) (It's worth noting that the Grid Premier skin is available for FREE just by linking your account to the mobile game. Five Premier Skins: Power Girl (Supergirl), John Stewart (Green Lantern), Reverse Flash (The Flash), Grid (Cyborg), Black Lightning (Raiden).Includes all Fighter Pack characters, Darkseid IS included.Three Premier Skins: Power Girl (Supergirl), John Stewart (Green Lantern), Reverse Flash (The Flash).Includes all Fighter Pack characters, Darkseid NOT included.
