The place — darker mood

Generated from: Keep the exact same layout and content as the source image: a hand-drawn level map of a small first-person zombie survival map on the left (round central chamber A, rooms B, C, D with teleporters, H power room, control room G, connecting corridors) plus two isometric in-game camera views on the right (a big industrial hall with catwalks and a lower chamber with a central machine). Same simple readable shapes, flat colours, clean ink linework, small first-version game look. Change only the mood: make it darker and gloomier — deep desaturated blue-grey and cold teal palette, dim shadowed interiors, faded lighting, muted browns and rust, fewer bright highlights, soft dusk tones with pools of low light instead of even daylight. Keep all rooms, letters, arrows and labels legible.
