Successor to smash-hit Operation Flashpoint, the sequel (dubbed Dragon Rising) will be rising on Steam's top-sellers list this weekend. You will be able to find it for 75% off from now until Monday. Dragon Rising is produced by Codemasters and follows up on the original Operation Flashpoint, published in 2001. The original game was credited as being one of the most realistic shooters of its time. If you want to see the game before shelling out the $7.50 bones for it, you can always nab a demo from Steam.
