Hello Sunshine At TGS2026: A Giant Robot Walks, You Follow
Red Thread Games has built its survival loop around a moving shadow rather than a base or a camp, so the safe zone is also the thing that keeps walking away from you.

At Tokyo Game Show 2026, the Norwegian Games booth in Hall 8 hosted a demo of Hello Sunshine, developed by Red Thread Games. The protagonist crosses a sun-scorched wasteland behind a giant robot called an OPPA, whose shadow is the only reliable shelter. Direct sun fills a body temperature gauge in roughly ten seconds; in shade, a hydration gauge drains from the heat. You leave the walking robot to loot water and recovery kits from roadside shops and factories, then dash back before it moves on.
The demo drops the protagonist into a wasteland with no fixed base and one piece of infrastructure: an OPPA, half-buried at first, that starts walking once it is found. Its back reads FOLLOW, and following is the whole job.
Shade and sun set the tempo. Direct sunlight fills the body temperature gauge in a little over ten seconds by the writer's feel, and the gauge's shadow shrinks as the sun rises, so the OPPA's own shadow gets narrower and riskier. Evening, when shadows stretch long, opens up bigger buildings. A sandstorm counts as shade and widens the map while hiding it. Guard robots shoot if you enter the wrong facility, and the OPPA will not wait.
