The PS Vita release of Rayman Legends is reportedly missing content found in other version of the game, according to a post on NeoGAF.
Missing levels are said to include all 28 "Invasion Levels," high-difficulty speed runs that challenge players to finish the section as quickly as possible. As the PS Vita version is being delayed in Europe, it's suggested that a patch may be underway.
In an earlier statement from Ubisoft, a representative told Polygon the Vita version has been delayed in Europe "in order to apply the final level of polish gamers expect from a Rayman game."
We have contacted Ubisoft; however the publisher has declined to comment until later today.
