To play this custom level:
- in classic DOS mode (classic graphics) and partial soundtrack - run TOMB_DOS_BASIC_START_HERE
- in DOS mode with glide (enhanced graphics) and full soundtrack) - run TOMB_DOS_GLIDE_START_HERE
In this level, the only missing track in case of using the classic exe with partial soundtrack is Natla's voice line.
(I tried to apply tombati.exe but failed - you may try but you need Treeble's GLRage pack not included in this download - check Unofficial Custom Level Forum thread on forum.trle.net)
