For a demo it's pretty comprehensive. You get to complete four lengthy missions and even complete the checkpoint running between the three and you're given a pretty long leash to explore the world around you, eventually you over step the boundary and fail the mission, but its a big boundary. On top of that you get to see some the gorgeous comic book panel opening sequences. You also get to explore the full range of your powers at both ends of the Fable like Karma meter that affects both your appearance and abilities.

First you start at medium Karma and have to rescue a trapped train full of civilians. Standing on the lead carriage energises the train and gets it moving, you just need to blast cars of the tracks and kill any Reaper gang members that try and stop you. Just standing in the proximity of electrical devices often causes you to power them up and when you stand in a puddle of water it becomes electrified, shocking anyone else standing in it. Here's a rookie tip, don't try and go swimming, it doesn't kill you immediately but falling in water causes you to get a big dose of damage. Later in the demo you find out your characters girlfriend has left him, I can only assume it's because he hasn't showered since he got his powers.

In addition to punching and kicking, you start of with the ability to shoot a sharp blast of electricity, throw a sticky grenade of power and send a wave blast of energy. All these powers are enough to take out your enemies with little trouble, but the last two can often unintentionally wound civilians. When people are wounded you can choose to heal them (good) or suck their bioenergy out (very bad). Bad guys who are injured you can leach or restrain for good points. At some points in the first mission you need to hop of the train and fire up a breaker box so the train can continue. At these points you get ambushed by Reapers with machine guns, or RPG wielding enemies and kamikaze troops that ran screaming towards you covered in dynamite. Most exciting were the attacks by Conduits, tall white coated bad guys who had similar powers to yours plus the ability to teleport.

The second mission was a simpler affair, just kill a bunch of Reapers and get rid of a tar pump that was poisoning the local water supply. You're Karma level was set to full badness and your offensive powers, notably grenades, were made a lot stronger. If you hadn't all ready, you got to do a bit of climbing and Assassin's Creed style roof leaping here. The movements are not quite as fluid and intuitive as Assassin's Creed but they're pretty good. Surfing along power cables in a hail of sparks is fantastic fun. The third mission was from our ex girlfriend Trish, guarding a bunch of medical supplies from Reapers. This mission really challenged the combat abilities and required me to actually use cover at some points that I hadn't bothered with before.

Lastly the Karma level was switched to full goodness and we were given access to Electrical Storm, a huge area of effect power that blasted everything around you to bits. Our mission was to ambush a gang Reapers and destroy they're truck which, after the last levels combat overload, was not too much trouble at all and the Electrical Storm power, where your hero throws his arms up and brings down lightening strikes all around him, made short work of the truck.

We got to use some other abilities as well, holding R1 when you jump lets you hover through the air and hitting the square button slams you into the ground and sends an electrical wave all around you. Thankfully falling doesn't cause any damage as you do fall an awful lot.

The demo does highlight a few problems with the game. The melee attack can be a bit useless as its hard to get close to bad guys without being riddled with bullets, it's not easy to tell what health you have left until things suddenly go all grey and you know you should get in cover immediately. Jumping onto objects like drain pipes isn't always exact, unlike Assassin's Creed that guessed what you were jumping for, you need to land right on it. You also can't lock onto bad guys, you get a little auto assist with your aim mode, which you use for all your power attacks, but its sometimes hard to track bad guys. Especially the teleporting Conduit's when in aim mode. Really, these complaints are nit picking, Infamous is quality from top to bottom and the demo has completely and utterly sold me on the finished product.

The game itself would have to screw the pooch pretty seriously to not live up to my expectations now.
