Tengen Toppa Gurren Lagann (Nintendo DS)

Tengen Toppa Gurren Lagann (天元突破グレンラガン) is an adventure game for the Nintendo DS based on the series.

Released just one month after the end of the TV series, it appears to have been worked on at the same time as the broadcast, and features the same storyline, with a few new and exclusive additions.

OVA / Episode 5.5
A limited-edition version of the game was released bundled with a DVD containing a short OVA (also known as episode 5.5), meant to introduce two of the new characters and bridge the gap between the anime and game.

Reception
The game received a mixed review on its initial release, with fans remarking on the unconventional battle format, downplaying of certain characters and disappointment over the Anti-Spiral, however it received praise for its faithful reproduction of the anime’s charm and the wide range of interesting skills that can be collected.

The extra content was also a hit, with the alternative ending making the game noted as a must-play for any fans of the series.

English Translation
An unofficial fan-translated English patch for the game was released in January 2021. It is fully playable and includes an accompanying walkthrough with a guide to unlocking the alternative ending.

The patch features several bug fixes and improvements, including new sprite animations and a cheat code to access a hidden debug map left behind during the game’s development. The release also included a remastered version of the original fansubs for the OVA.
