GSE Heads to Tokyo Game Show 2026 From September 17 to 21 With Newly Announced Titles

Game Source Entertainment (GSE) is heading to Tokyo Game Show 2026, running for five days from Thursday, September 17 to Monday, September 21, 2026, at Makuhari Messe International Exhibition Hall. GSE welcomes visitors at Booth [Hall 2, N02], where several highly anticipated new games will be available to try out ahead of their release. Visitors who complete the hands-on demos or take part in booth activities can also pick up an assortment of limited-edition novelties.

Ratatan (ラタタン)

Ratatan, the new side-scrolling rhythm roguelike action game from Hiroyuki Kotani (小谷浩之), creator of Patapon, returns to TGS.

Players fight alongside "Kobun" and other companions, defeating enemies by timing rhythm commands as they advance through each stage. At the booth, visitors can get an early hands-on look at Ratatan ahead of its October 15 release. Visitors who complete the demo or take part in the booth's social media activities, among other conditions, can receive special venue-exclusive merchandise.

THANKS, LIGHT.

THANKS, LIGHT., a new 3D puzzle game built around manipulating light and shadow, has been confirmed for Tokyo Game Show 2026.

In THANKS, LIGHT., players use a flashlight to control light and shadow, switching between 2D and 3D perspectives to find a path forward in this first-person puzzle game. Ahead of its October 15 release, a hands-on demo at the TGS2026 booth lets visitors experience the game's original world and its latest mechanics firsthand.

Shine light to "materialize" shadows, and absorb light to "nullify" them — visitors can enjoy this inventive, convention-defying puzzle experience at Makuhari Messe.

Noroi Ayashi (ノロイあやし)

Noroi Ayashi, a brand-new horror RPG created by Rensuke Oshikiri (押切蓮介) and Sohei Niikawa (新川宗平), has also been confirmed for Tokyo Game Show 2026.

There is no playable demo of the game at this event, but the GSE booth features a dedicated photo spot. Visitors can pose alongside the game's eerie apparitions for a special "spirit photo," as if stepping into the game's own world.

Visitors are invited to stop by the photo spot and take home a uniquely eerie souvenir photo found nowhere else.

Castle of Alchemist

Castle of Alchemist, the highly anticipated title from indie game studio Team Machiavelli, has also been confirmed for Tokyo Game Show 2026.

Castle of Alchemist blends the careful strategy of tower defense with the fast-paced thrill of action RPG elements for a new take on the action tower-defense genre. Players take on the role of Bellator, a guardian empowered by alchemy, using trap placement alongside direct combat across the battlefield to defend the castle from an advancing army of machines.

Visitors who try the demo at the booth receive a limited-edition novelty: a two-design holographic sticker set. Visitors are invited to stop by the booth and experience the thrilling battles where strategy meets action.
