The PS Vita version of Rayman Legends is missing content compared to the Wii U version, but luckily the Vita version will be patched to bring it on par with the console versions. The game suffered a two weeks delay on the PS Vita and the Invasion levels are missing from the game, but Ubisoft have confirmed that these will be available “at a later date”.
The patch will be free to download according to Ubisoft’s communications manager in the comments on the Ubisoft blog. No release date for the patch has been revealed yet.
