Amphitheatrum - it's small simple fun map for HLDM, that I made when was boring. 2 days ago map was ported to Deathmatch Classic, and new version has some differences (retexturing, weather effects). So, I think, DMC version seems and plays better, than original.
Sorry for bad English grammar.
UPDATE 22 April 2011
- added detail textures (use r detailtexturessupported 1 and r detailtextures 1).
- added .res file
