Played it with my brother, good time, strange part of Half-Life's PS2 port. I find it very interesting how it ties into the events of HL1! It's strange that the weapons have no viewmodel (except the crowbar, that's an exception for some reason.) The game controls feel clunky at times and I hate that you have to restart the entire map you're on when both players die. Also when playing, there were some issues with the sounds. Could've been executed better, but the time I had with it was really good.
