CROSS.WAD is a single-level deathmatch PWAD designed by Alistair Brown. It is notable for being one of the first Doom mods ever created, having been created programmatically with code written in C++; it was originally released March 11, 1994.

This level should not be confused with CROSS.WAD by Kuranes, a much larger deathmatch map from 1997, or Terry Henning's CROSS.WAD (May 1994), a fairly conventional solo map with several hundred monsters. The latter saw a bug fix release, renamed to CROSST.WAD for this reason, and Alistair Brown's level was later distributed as CROSSA.ZIP.

Map layout[edit]

Strictly speaking, this level can be completed in solo mode, but since it includes no monsters and only one room with the exit switch clearly visible, there is not a great deal to say about it. Co-op start points are absent.

Player spawns[edit]

This level contains four spawn points:

  1. facing east. (thing 0)
  2. facing south. (thing 1)
  3. facing north. (thing 2)
  4. facing west. (thing 3)

Technical information[edit]

According to the author, the BSP calculations required to construct this map aided the development of DEU's final node builder.

Inspiration and development[edit]

When Origwad was announced on alt.games.doom, Alistair Brown replied that he also had created a PWAD by hand, which consisted of a small square room with a cyberdemon on a central square platform. This level had been used when reverse-engineering the BSP structure but was never released. CROSS.WAD was a slightly more complex level but allowed the theories derived from the simple level to be tested and proved. After CROSS.WAD was released, Alistair followed up with a lengthy technical explanation of the design process, which is included in the idgames package as MAKE-LVL.TXT.
