I like almost everything about this mod, it is great! My only critique is that you replaced a lot of the iconic sound effects from the original game with new ones, like the small green portals that spawn the aliens, the aliens itself, doors, gateways, trains etc. I think that decision removed a bit of the atmosphere and flair which the Original Game made so special. The sound editing per se is very well done and professional, but I think it doesn’t fit in the HL Universe or let’s say that I think the original sound effects fit much better.
