If you're among the few people who were disappointed by Modern Warfare 2, you may be interested in another, lesser-known first-person shooter that just released a demo. Operation Flashpoint: Dragon Rising is a tactical military simulator which debuted on October 6 for the Xbox 360, PlayStation 3, and PC. The title is a sequel to 2001's Operation Flashpoint: Cold War Crisis, and the expansion pack Operation Flashpoint: Resistance.

The game is set on a Chinese occupied fictional island in the East China Sea called Skira, where you play as a part of the US Marine Corps tasked with retaking the island. The game embraces an open-world sandbox design, and allows you to explore a 130 square mile island, which contains over 50 drivable vehicles (include land, sea, and air), and more than 70 weapons.

The demo allows you to play through the first mission from the full game, and includes both single-player and co-operative multiplayer modes. You can download the demo now via FileShack (1.39GB).
