The campaign outlined in the book is fairly fun and I will definitely run it with some peopel at some time...
But what I really wanted this book for was to create my own Xenomorphs campaign. All we really need is a template to make other races Xenomorphs and it makes this fully cross compatible with anything WOIN.
I mean think of the crossover possibilities. Batman VS Judge Dredd VS Xenomorphs VS Predators is almost fully supported in the WOIN universe.
Using this, the NEW core rulebook, and The Last Star Knight supplement, you can make a more amazing Xenomorphs Star Wars crossover than is even remotely possible in Star Wars D20 (trust me, I've tried)
This book is pretty great, I have no complaints. After running homebrew Xenomorphs in other systems that needed too much tweaking, I was happy to see these majestic beasts made available from the publisher :)
