Heat Death Survival Train Demo
Controls work smoothly and PC-friendly settings—graphics, binding.
I spent ~30 minutes all-in, mostly exploring the menus and 4 buildings—2 x habitats, control center and train station—in the barren starting location on what seems like some faraway planet. There are 8 people's living quarters, but nobody around so far.
It's a survival game, with a max-weight inventory system—30 KG for me, of which I'd filled ~12 KG when I quit. You pick up blueprints while exploring, and various materials—presumably for use in 2 crafting stations in the train station.
You have 3 meters—health, stamina and energy—to take care of. I found batteries to power my suit, and recharging stations for used batteries, plus some food scraps. Nothing taxing so far, I only used up a lot of energy while using my flashlight in some dark areas.
Not my genre, but seems decent quality.
