Ah, the barrier peaks book of WTF?!? If you want to see a weird preview of Metamorphosis Alpha in your Classic D&D game, this is it... Weirdly layed out (there are two thirds of the .pdf made up of artwork, varying in quality and some in full colour) and woefully unbalanced. It'll kill dozens of PC's regardless of level, but those who claw their way out will have the most ludicrously overpowered sci-fi weapons going... Er... If you like the idea, go for it.
