The US PlayStation Blog's uploaded a massive playthrough of the latest Ratchet & Clank: All 4 One demo build.
The video, commentated by the game's designer Chad Dezern, focuses on new elements introduced in All 4 One. Most notable is the new camera position and character roster.
It all looks like a bunch of fun, and pretty well polished at this early stage of development. We anticipate getting our hands on the game and trying it out for ourselves, but there's a lot of potential for this title.
There are more details on the PlayStation Blog.
