Directly after the game's release, development on a predecessor called HacX 3-D
(or HaxX 2
) was started, but eventually dropped. The complete story can be read on the official website
Some time after the original release, the add-on was released as freeware download version. In 2010, version 1.2. was released which no longer requires DOOM II
to run. As of 2012, a version 2.0 is in development.
The developers rushed the game so it could be released before Quake
. Therefore the game was unfinished and unpolished.
