<P>You find yourself standing on a rooftop, overlooking a tower. You have to blow up a generator inside. Guards patrol outside, dogs yapping with their probably rabid mouths. You shrug. You've broke into worse places. Waiting until the patrol routes move away, you crawl silently to the ladder, ascending to the roof. Looking through the skylight you notice two guards chatting, spouting conspiracy theories about the government. You listen for a while, then lob a gas grenade down, reducing them to choking heaps, wiping their eyes. You leap down, applying knock-out blows to the back of their heads. All's silent. You head down, noticing a couple more guards walking long patrol routes. When one turns his back an electric prod to the back of the neck brings him crashing to the floor. His yelp attracts the attention of his partner, who turns the corner only to get a face full of pepper spray. A truncheon blow and he collapses. From then on it was easy. Down a floor, crawling into the computer room. By hacking the computer system you're able to program an auto-destruct of your target. You retreat back to the roof and escape. No-one will know you were ever there. Death count? Zero. No more tears on the face of the mother of the world thanks to you.

You shrug, shoulder your sniper's rifle and put a 30:06 round through each of their heads. You hate patrolmen and - hey - you aren't too fond of dogs either.

<P>You find yourself standing on a rooftop, overlooking a tower. You have to blow up a generator inside. But by doing a few favours to your street-friends and throwing around a little cash, you've managed to gain every single security code, key and password for the facility. The second you find a security console, those gun-turrets on the first floor are going to be turned against their makers.
