This script has promise. I did crash in the recharger room when I had fists up and attempted to switch weapons. And I do a lot more dying than killing, since I seem to take a lot more of a pounding than the turret. And the requisite charging of health (shields) at the start of each life is wearying.
As a fan of weird netmaps and netscripts, I'd be interested in seeing how this could be made into a net game, once the bugs are worked out.
P.S.: StuffIt Expander opens this on a Mac.
Experimental gametype with .lua scripting (map compatible with script enclosed). More details in readme file.
