Ratatat
PR TIMES" Ratatat," the much-talked-about new side-scrolling rhythm roguelike action game from " Patapon " creator Hiroyuki Kotani, is making a return appearance at TGS.
This game offers a fresh take on action gameplay, where you advance by defeating enemies using rhythm-based commands.

PR TIMES
Plus, if you participate in the hands-on demo or social media events at the booth and meet specific conditions, you’ll receive special merchandise available only at the event.
Check out the details at the venue!
THANKS, LIGHT
PR TIMES " THANKS, LIGHT. " is a new-style 3D puzzle game scheduled for release on Thursday, October 15, 2026.
Use a flashlight to control light and shadow, and carve out a path by switching between 2D (flat) and 3D (three-dimensional) worlds!
Why not try out this innovative puzzle—which defies conventional wisdom by “materializing” shadows when you shine a light on them and “neutralizing” them by absorbing the light—at one of our demo stations?
Ayashi Noroi
PR TIMES"Noroi Ayashi," a brand-new horror RPG created by the collaborative team of Renji Oshikiri and Sohei Shinkawa.
Although there won’t be a playable demo for this title, a special photo spot will be set up inside the GSE booth!
You can take “spirit photographs” alongside the game’s eerie supernatural beings, making it feel as if you’ve stepped right into the game world.
Castle of Alchemist
PR TIMES A demo station for the highly anticipated title “Castle of Alchemist,” developed by indie game studio Team Machiavelli, will be available.
This game is a new take on the action tower defense genre, blending the need for meticulous strategy with fast-paced, exhilarating action RPG elements!
Take on the role of "Verator," a guardian enhanced by alchemy, and master both placing traps and engaging in direct combat as you race across the battlefield.
Defend your fortress against the advancing mechanical hordes.

Try the game at the event to receive limited-edition " Hologram Stickers (2 types total)."
Why not stop by our booth and experience the exhilarating battles where strategy and action collide?
TGS 2026, where "GSE" will be exhibiting, will be held from Thursday, September 17, 2026, to Monday, September 21, 2026.
