To both of you.

Xen is coming out later. They thought they had taken long enough to get it released and since everything up to Xen was finished and with the fact that as soon as you land on Xen it becomes a totally different game, that they would release it now.

There is no reason for you not to play it SewerUrchin. You will still find it to be a great gaming experience.

However if you don't mind old-school graphics, I highly recommend you pick up the original HL and play it first. It truly was a ground breaking game and we owe a lot to it.

And once you get T-bagged by the "Bouncy Testicle Monster" you will realize why most of us hate Xen with a passion.

But with that said... once the Black Mesa team releases Xen I will download it and play it.
