This is essentially what White Light should have been. Gameplay is worlds more interesting (different enemies on each wave as opposed to there just being greater numbers), the annoying "everything goes red" moment has been cut, Justice has been put in (with ranged alt-fire) to get use out of it and make the map play differently, the scripts are cleaned up... There's a huge number of changes in 4 hours or so. I'll keep the old version about as a seperate release due to the 4 year age gap but I'd consider this version the greater by far.
I'll hold off the /idgames upload for a few days as I've only tested this a few times to make sure it all works. A user-trial is probably all it needs now! Enjoy
