A modular PS1-style fallout shelter and the sewer beside it, for your survival horror game.Built-in and URP: every material uses the pack's own unlit shader, one pass that both render, with Unity's fog. Not HDRP, where the materials show magenta until given an HDRP Unlit shader, which loses the PS1 look.A modular PS1-style fallout shelter and the sewer beside it, for your survival horror game. 229 pieces that snap to a 2 m grid, in 14 rooms: bunker corridors, the dormitory, the control room, the plant room, the stores, the mess hall and its galley, the ablutions, the sick bay, the armoury, the overseer's office and the command room, and past the blast door the sewer's tunnels, a cistern on brick columns and the shaft to the street, with the bunks, mess tables, beds, rifle racks, plotting table, switchboard, sump pump and a squatter's camp to fill them. 53 of them move: the bulkhead door's wheel turns before it swings, the armoury door's bolts shoot back, the hatch's shutter rolls up, the gate winds up. Machine.cs runs the 28 machines (the generator starts, the overseer's door takes its key, the keypad takes the code and lets the armoury go, the fuse fits, the lever pulls, the blast door opens, the pump starts on its crank and the gate winds up), wired by what needs what, with UnityEvents for what they do. Low-poly and point-filtered, a prefab per piece, and a demo level of 451 pieces to walk and solve, for Built-in and URP. It shares PSX Hospital Kit's grid, so the kits build one another's floors.Unity 6.3A .unitypackage with a prefab per piece (colliders and animation clips), Machine.cs on the machines, a PSX unlit shader for Built-in and URP, a demo scene and the level to walk and solve.Every model, texture and animation is made by Python code, run in Blender, that an AI coding agent (Anthropic's Claude) wrote, as are the shader and the demo scripts; no generative image or 3D model made any of it.229 pieces, 2 to 1140 triangles each (41622 in all); the full list with sizes is in Documentation.txt.Textures: 28 PNG (2048x2048, 27 at 128x128), point filtered, colour only: the shading is baked into vertex colours, so no normal maps.UV mapped, no LODs (one low-poly mesh per part), no rig: 53 pieces move their parts in 71 animations (Legacy Animation clips).Real-world scale, 1 unit = 1 m, pivots on the floor or wall they rest against.A prefab per piece with box colliders on its parts, one material, a demo scene, and the demo level to walk (Demo/L_Level.unity, a first-person controller).Render pipelines: Built-in and URP: the materials use the pack's one-pass unlit shader (vertex snap, fog, and an affine texture warp to turn on), which both render. Not HDRP.Unity 6.3 or later, in the Built-in pipeline or URP.A Documentation.txt in the package's folder says what is where and how to use it.
