Based on the elite squad-based Special Air Service (SAS) that had its beginning near the start of World War II, the Hidden & Dangerous series focuses on units designed to infiltrate enemy positions, carry out special assignments and conduct specialized operations.

Gameplay in the original Hidden & Dangerous revolves around six distinct campaigns, each divided into individual missions. Missions must be successfully completed before the next can begin and, correspondingly, all missions of a campaign must be completed before advancement to the next one can occur. Each mission can require a team of up to four commandos, chosen from an international field of 40 available, each with individual attributes, abilities and specialties.

With the expansion, Hidden & Dangerous: Devil's Bridge, Illusion Softworks and Talonsoft have added nine new missions to the original game's 23, and have spread them across three expansive campaigns. In the campaign Operation Mystical Wings, (set in 1944), you will go deep into Axis-occupied Poland to steal a German jet bomber prototype. The two missions for this campaign are Phoenix Flight and Phoenix Dust. Operation Green Hall is a campaign set during the Battle of the Buldge (Ardennes, 1944), you will have three daring missions -- Devil's Bridge, Forest of Nightmares and The Last Fortress. You will disrupt German supply lines, rescue captured American soldiers and more. The last campaign, Operation Red Alert is set in 1946 post-WWII Greece. Guerrilla warfare continues to rage, and the job of your squad is to prevent a resurgence of Communist partisan activity. The missions for this campaign are Hand of Darkness, Lost Valley, Fallen Gods and Osprey Nest.

The game features changeable weather patterns (rain, snow and fog), varying objectives and real-time movement through diverse terrain and locations. Viewpoint options vary from either first- or third-person perspectives. The world of Hidden & Dangerous is not stagnant, as objects within the environment move and react causing active strategic and tactical planning.

Up to four players can cooperate per team over a LAN or the Internet, and an optional voice chat program Roger Wilco, is available on the disc install. You will need a headset and microphone to use this feature, but once it's part of the game you can communicate with all the members of your multi-player squad verbally in real-time!

The game comes with a wide-ranging arsenal of WWII equipment, weapons, vehicles and objects from communication devices to camouflage uniforms, explosives and sniper rifles. Hidden & Dangerous assigns and tracks a player's specific "profile" from the beginning of the game, updating and assigning scores for each mission, with the resultant ratings having an impact on future missions.
