Works, I guess, and any Lua programmer instantly gets a thumbs up from me. Crashing more often is bad, though, and I'm not sure how many people would use it. Overall great.
The number one comment I hear when hosting the Co-Op 2.0 Lua script is, "I really miss the old script."
Now, with the Co-Op 2.0 - 1.0 Edition script, those players will feel right at home.
This modified script spawns players with full health. By default, players will be "slaved" to the host's beacon, simplifying the teleport system for new players. The HUD elements from the original script also return, showing deaths, kills, and enemies remaining. While in the map view, helpful text explains how to set beacons, change targets, and initiate a teleport. Also, this script crashes more often.
