Bohemia Interactive Studios has put a ArmA II demo up for grabs. Get it while it's hot.

If you haven't heard of the PC military FPS, you might be missing out -- if you like your war-games realistic. The game puts you in the boots of a solider, and strives to re-create the chaos and sudden death situations of actual warfare. You will not be bursting into a room with a machine gun, taking five shotgun blasts to the chests and then using medkits to recharge your health instantly in this game.

Currently ArmA II is sitting pretty on Metacritic with a score of 79, with some critics scoring the game much higher, saying it is a title that should not be missed if you would "enjoy the most varied opportunities for combat in a very realistic representation of a war scenario, vehicles, weapons and characters" (said website Meritstation). "ArmA 2 represents the absolute freedom facing a modern battle, and where each of our choices will bring consequences."

Here's the word on what the demo does and doesn't have: "The fictional post-Soviet state of Chernarus provides the location for all the action in ArmA II and gamers will have the opportunity to explore its highland area in the demo version, along with the small Chernarussian island of Utes. More specifically, the ‘boot camp’ missions are all available which act as tutorials for the game’s many disciplines including helicopter flight, unit command and base construction. In addition, the full single player mission ‘Trial By Fire’ from the main campaign and the multiplayer map ‘Mini Warfare’, allowing ArmA fans the chance to trial three multiplayer modes, are included in the demo. A selection of over 20 vehicles, over 25 weapons and various soldier and civilian models will be included, although these represent only a fraction of those available in the retail version."

Below are the system requirements.

•  Windows XP / Vista
