The Obsidian Edition is simply a ‘multiplayer enhancement’, changing the gameplay of the game. Detail such as floating bodies, teleporters which teleport shots, a harpoon with cable-wrapping dynamics are added. Rules have been changed, along with most of the weapons. This patch is CTF compatible, so it WILL work with your basic Threewave-CTF levels. Since there are so many sounds used, the sound buffer is all filled up and most single player levels (unfortunately) won’t work. Sorry.
