Sucker Punch plans to release an inFamous demo on 21st May, according to the developer's website.
That's just over a week before the PS3-exclusive launches across Europe on 29th May.
InFamous follows the adventures of Cole McGrath, a bike messenger-turned-superhero after a huge electrical explosion. He soon finds that he can frazzle people with lightning bolts as well as manipulate electricity in many other ways - good or evil.
