2D top-down pixel art sprite sheet, exactly 512x512 pixels, transparent background. The sheet is divided into an 8x8 grid of tiles, each tile exactly 64x64 pixels. Row 1, tiles 1–8: sequential animation frames of the same zombie walking. Row 2, tiles 1–8: sequential animation frames of the same zombie attacking. Row 3, tiles 1–8: sequential animation frames of the same zombie dying. All zombie animations should be consistent in size, style, and facing direction, drawn in retro pixel art style with clean outlines and sharp edges. Remaining unused tiles in each row should contain alternate zombie parts (weapons, arms, legs, heads, torsos) matching the same style and color palette. Use a fixed top-down perspective, consistent lighting, no extra borders, no background, no drop shadows. Each tile perfectly centered. See more
