Well, for anyone wondering...
The game is based off the British comic series 2000 AD. You're Rogue, a genetically enhanced super soldier and ex-member of the Blue Man Group, whose sent down to the Quartz Zone (which looks like the eastern part of Africa, according to the Nu Earth load maps) on Nu Earth. You go down with 3 friends: Gunnar, Bagman, and Helm. Gunnar and Bagman are shot and killed in the Quartz Zone... Well, not entirely killed. Each soldier has a biochip that can be taken from them and embedded into weapons. So, after you encounter a dying Bagman and Gunnar, you install them into your backpack and gun, respectively. Anyway, the entire invasion force (which is you) is told to retreat, but gets massacred by the enemy forces, except for you. Helm is kidnapped, you go rescue him, but he dies and you install him into your helm. That's about as much as I'll tell.
The game is a combo of standard third person shooting, tactical shooting, and stealth. Each of your biochip-installed pieces of equipment can do unique things. Gunnar in your gun is more accurate, can change around into different guns (sniper, rifle, shotgun, etc), and also be deployed as a turret. Helm can hack into computers and doors, attract a guard (similar to banging on walls in Metal Gear Solid), and project holograms of you to fool bad guys. Bagman can produce weapons, ammo, and upgrades for you, as long as you salvage materials (which you get from miscellaneous garbage as well as dead baddies).
From the few levels I've played, it's quite a bit of fun. Stealth isn't as great as I'd like, but it's still pretty fun. I suggest it.
