A unique experience, let down by the difficulty, results in a hit and miss with a lot of gamers.
The draw to this game is the "feel and flow" that you get when you are stringing moves together to gain mommentum without stopping, as you run from the law.
Pro's: Mirriors Edge is one of a kind, being no other game puts you in the shoes of a runner in FPS. When you do achieve the "flow" the game is very fluid and feels great. The combat system is short yet challenging and the maps are beautiful to look at in its own way. The sound is breathtaking.
Con's: Being one of a kind, it didn't have other games to look at for help, and it shows when trying to achieve that "flow." The game itself isn't fluid your 1st time through because you don't know the map, so knowing where to go can be frustrating. So can your 2nd or 5th time through. Since you often have to stop to look around and figure out where to go, the "flow" is pretty non-existant. Your jumps have to be perfect, you can only take 3 hits or less from guns, and the hint button is often useless.
Gameplay: You run, jump, and occasionally disarm and use a weapon that you throw down after a few shots. It doesn't get any deeper than that.
Graphics: Unique. Very simple colors make the world look pure. Some will love it, others won't think too much of it. Characters look very realistic, but the cut-scenes look like an ESurance commercial.
Sound: Terrific. The wind blowing as you jump and hearing Faith's breath as she runs is great. The soundtrack is awesome and beautiful. Sound effects are top notch.
Difficulty: Hard for a few reasons; the margin for error on jumps are non existant. You either make them perfectly or fall to your death. The law can hit you a mile away with scary accuracy and you don't take many hits. Maps are often confusing and paths require some degree of problem solving.
In conclusion, Mirrors Edge relies on the gamer to think on the run to achieve the "flow" needed to enjoy the game. Unfortunatley, this is rarley achieved due to many stops needed to figure out where to go and the margin of error being so small. Some will enjoy this game, most won't, but you will figure out which side of the line you are on within your first 10 mins of gameplay. Most agree that the only "flow" this game achieves is a flow of frustration.
