A mod has surfaced to finally bring mouselook and configurable controls to the old classic. Anyone who was struggling with the industry's first attempts at FPS controls...(and they are a bit clunky) go to [url=]http://www.strangebedfellows.de/index.php?topic=1719.0[/url] for a slice of mouselook magic.
