16 maps + start map created to fit the same limits as the original Quake campaign:

• BSPs had to be able to fit on a 1.44MB floppy (usable space 1,457,664 bytes)
• Maps could not use more than 64 textures each
• Running r_speeds should not display world polygons greater than 350 on average, and 600 maximum.
• Maps had to be FULLY compatible with the original executables for DOS and Windows: No coloured lighting, fog, lightmapped liquids, external skyboxes, fence textures, transparent liquids, alpha-transparent brushes, or any other engine features that weren't supported.

The event ran from 18/04/2026 to 01/05/2026.
