One thing is true, STEAM has always run, but there are at STEAM offline mode.
Just then, it is possible every game (I speak of HL and its mods) on LAN play.
As for the graphics, well, it's not the newest and not the best
but that is not in this game.
It is a pure tactics shooter and should also be considered as such.
In addition, the game was, I think, developed in 1997 and was still a pure mod for HL1.
The game is basically one of the pioneers for all today's multiplayer shooter alla CoD MW etc.
Therefore, and because I have are the beta on my computer got there it 5 stars.
