Crocodile Entertainment will be releasing a demo of their 2D side-scrolling shooter Zack Zero to PlayStation Network tomorrow. Subject to a fairly severe drubbing in reviews (including our own), the visually attractive but technically-challenged game received a rather significant update and it seems Crocodile is hoping that people will give it a chance if they don't have to pony up cash to do so.
The update doesn't address all the problems reviewers had with the game (some of the issues appear pretty fundamental to the design), but there are some major changes. Fall damage has been removed, control improvements have been implemented and an annoying "level up" screen has become an opt-in affair. I figure if they're going to put that much work in, I can give the demo a try.
