The debut release of the Dino D-Day modification for Half-Life 2 is now available, offering a World War II/dinosaur mash-up that's a prototype for an upcoming commercial release. This page offers a trailer showing it off, and here's word: "Dino D-Day is an exciting new First Person Shooter from Digital Ranch Interactive. You’ll play as Sgt. Jack Hardgrave, a renowned paleontologist who thought he put his career on hold to go to war…then Hitler resurrected dinosaurs and unleashed them on the Allies in 1942. When the Fuhrer’s monster army saw battle for the first time in North Africa Hardgrave was on the front lines – nearly getting eaten alive by beasts he spent his life studying. This is an HL2:OB mod that has served as a prototype for a commercial release of Dino D-Day slated for 2010. We look forward to community input on this early version of Dino D-Day as we continue crafting the game over the next several months." There's also an interview with the mod's co-creator on Big Download.
