You'll be able to play through the opening chapter from the game (like above, but probably better than I fared), up to the conclusion of the Mako Reactor 1 bombing mission. Anyone who downloads the demo before May 11th will also receive an exclusive PS4 theme for their interest. No word if it's the same as the theme you'd pick up if you eat enough Butterfingers candy.

I got to play several more early chapters -- read our preview here.
