One more up-dating for already familiar map. The Other — the quite good alternative to Black Mesa map (look for a map on our site), but its level of execution slightly doesn't hold out to the vis-a-vis. On it there is everything — turrets, secret laboratories, G-man and even a press which obviously removed from "Star wars" here. In the new version the author finished optimization and added physics of objects from Half-Life 2.
