Planisphere 2

Planisphere 2 is a single-level WAD for strongly limit-removing source ports, released in 2012 by Perro Seco. It is a replica of. It was a runner-up at the 19th Annual Cacowards.

Bugs

 * The level does not include any of the lumps created by a node builder, and will therefore only work in source ports which feature an internal node builder, such as ZDoom or Risen3D. (The author recommends GZDoom.) The level is too large to create regular nodes. It can be played in PrBoom+ if extended nodes are built with ZDBSP or DeePBSP.
 * The dimensions are so large that collisions and hitscan traces will glitch unless using a port which fixed the blockmap overflow bug.

Trivia

 * Despite being set in 2040, the original is still standing.
