Nintendo company president Satoru Iwata has provided more details on the upcoming add-on content for the Wii U launch title, New Super Mario Bros. U.
The downloadable content, called New Super Luigi U, makes no changes to the world map but Iwata said Nintendo "has completely changed all 82 stages to let you experience a brand new adventure".
Speaking during a live stream of the Nintendo Direct conference on Wednesday, Iwata said: "It is like a brand new game".
The game's alternative star character, Luigi, is able to jump higher than Mario but does not have the same level of control - meaning that new challenges will be found within older levels.
Concluding the new approach is a new rule for the game; each stage starts with 99 seconds on the timer, meaning that players must dash through levels rather than stroll.
Coupled with more obstacles packed into each stage, Nintendo said the DLC will change the way people approach New Super Mario Bros U
The DLC is due for release this summer.
