Aeternum is a three-level WAD for Doom II, created by Paul DeBruyne (skillsaw). It was released on 27 November 2007 for the ZDoom source port. It marks skillsaw's return to the mapping scene after a decade-long hiatus since his last project, 1998's Sector 666. Aeternum is heavily influenced by Alien Vendetta, evident in the visual themes and the high difficulty found in the maps.
