Chasm The Rift will now have a publicly uploaded deathmatch pack at 8/21/2016.
It's a small deathmatch pack. made using the Chasm's Level Editor, you might notice that the player spawns are outside the map (editor is broken!) idk how to hex edit the positions of the spawns yet.
When you get it the folder name is supposed to be named DMPAK1. Also more news. in a Linux distro with Wine installed along with DOSBox. it is possible to run the UDP exe for Chasm. it goes directly to DOSBox and runs the game allowing TCP/IP.
Make sure your NAT network for virtual machines or computers are ready for some online deathmatch :P
I,ll investigate this method further. Stay tuned.
