As agent David Jones, it's your job to single-handedly shut down terrorist organizations, intercept enemy intelligence, destroy hostile installments, and escape in one piece. No new premises here, but it still sets the stage for a pretty fun game. Think
Metal Gear Solid meets
Thief II and you've got the idea.
Each mission sends the player deep into enemy territory with the capability to carry only one assault weapon, one small arms item, a knife and a few explosives. Being a covert agent, you'll need to remain unseen until combat is absolutely necessary -- and even then, try to keep things silent and clean. Of course, if you're the guns-blazing type, a few missions essentially require you to massacre over 30 enemy soldiers in the face of compromising your objectives; it's just all in how you plan your moves.
HQ provides you with one of the most useful items ever conceived in a first person shooter: the Zimo-Tech Map Computer, which links a real-time satellite image of your surroundings to a handheld screen. This allows Jones to see the entire landscape at a glance, with enemy locations highlighted in blue, and each objective numbered on the map. Just click and drag to scope out the environment, and magnify up to four times to see which weapons the opposition is packing. Too cool.
As for multiplayer, two teams scramble to defend rocket bases and installations from invaders, supplied by a full equipment shop a la Counterstrike. Online veterans won't find anything terribly innovative here, but it's a nice diversion from the single player mode. Besides, who doesn't like ambushing a hilltop full of snipers with just a knife?
