A recent Steam Forums thread said this game is still active with some servers that are almost, if not full. If you're in the United States, then you shouldn't have too much trouble finding games. If you can't find any, you can still use it for Garry's Mod. Either way, fun times to be had. Thanks to maxim2142 for the submission!

nice

Just a note.

You can get this game for free if you have an

ATi http://steampowered.com/ati_offer1a/ (also include HF2 Lost Coast

Nvidia http://steampowered.com/nvidia/ (also includes HF2 Lost Coast and Portal (You can get Peggle for free from the steam store!))

This game is free. Why would anyone waste points on having a small chance at getting it, while you can just download it for free.
Just search for the Steam Nvidia / ati offer.

I will have to partake in the offer... I have an ATI chip.

To the people who entered, make sure he is not sending you the promo link for the free game (as seen above)
