X is a heightfield engine written by code<sup>x</sup>.  Included in
the download is a DOS 32-bit executable (requires a 32-bit extender,
such as cwsdpmi.exe) as well as its DJGPP source code.<br>
<br>
The engine uses Chris Egerter's heightfield maps, which are, unfortunately,
fairly small, so you'll notice their isn't much room to move.
When neuraldk creates a new heightfield engine (possibly with 6DOF),
however, we will provide a larger, original landscape.
