Apparently bent on bringing the Internet to a halt in what's already a trying time for download sites, Activision has released the single-player demo for Soldier of Fortune II: Double Helix for download from FilePlanet (registration required). The whopping 136.9 MB demo includes two levels from the full game, Columbian Jungle and Seaward Star. Update: There are mirrors on FileFront, 3D Gamers and Fragland.net (Belgium).
I'm glad I got this demo to hold me over until I'm able to buy the full version... Ahh, nothing better than seeing a grenade detonate in the hand of a terrorist that picked it up intending to throw it back.
