2019 is apparently a renaissance of the Build engine. Just last week, we got proper source code releases for the original Shadow Warrior, the EDuke32-powered Ion Maiden is expected to release this spring, and today we got news that an EDuke32-based source port of the classic game Blood was created, called NBlood. Currently, it offers software and OpenGL renderers, CD audio and accurate FM OPL3(SB/AdLib) emulation, DEF/HRP support, and a rather unstable multiplayer mode.

You can download NBlood here, and see its source code here.
