DeePsea

DeePsea is a Doom level editor and WAD resource manager. It has full support for Doom, Doom II, Heretic, Hexen, Strife and any source port via custom configuration files. 3D texture alignment uses a variant of the Risen3D GL port, R3Dedit. Since R3Dedit is based on Risen3D, it is able to provide a view of a level with normal skies, as well as optionally showing the placement of all sprites.

It was developed by Jack Vermeulen of SB Software and is a shareware application. For the unregistered version, there is no time limit, but the maximum size of levels a user can create is limited to 800 linedefs or 1200 sidedefs. DeePsea's development is ongoing.
