You will spawn in a very big sand, in this sand, you can use very powerful weapons with various fire modes, you can use a panel for create various types of NPC, some very weak and others really aggressive and destructive, this arena is a great slaughterhouse, you may die earlier than thought...
The first version of HL:SOTD, have fun in this slaughterhouse, this mod is VERY old, it has some many bugs and crash errors, bad language and other things...
