One thing that was pretty innovative in this game when it came out was that you moved around with the keyboard, but aimed with the mouse. This allow you to run one way while shooting in a different direction. It’s neat to see the engine is still getting some love after all these years.
Oh yeah, I loved playing it when it came out as well. Was hands down one of the most innovative shooters of the time. I haven’t tried building it locally, but might give it a shot and see how that goes.
