I love this picture. It comes from the upcoming adventure pack for Deathwatch called The Emperor Protects. I might actually get this book solely because it lets me fight dinosaurs. The Price Of Hubris, the adventure that this picture is from, looks like it might be worth the price of admission all on its own. It's that awesome.
I really was hoping that in Deathwatch they would be including a lot of the 'backstory' creatures from 40k. I've always wanted my hero to duke it out with the vaunted Catachan Devil, for instance. Dinosaurs, however, will fill the need for historical monster carnage for the time being. Just look at that thing! I wonder how many bolter shells ol' Xenos Rex can take?
