The new Shadow Warrior really is very good. Flying Wild Hog learned a lot from Hard Reset and it shows. Level design is detailed and beautiful as usual with a new emphasis on earning secrets. And the secrets are exactly the stuff you'd find in the original Build engine games. I love how it's packed with easter eggs like Godzilla stomping along behind some mountains and a chunk of the original game hidden behind a waterfall. Melee combat is surprisingly well done and so satisfying. They definitely didn't skimp on the gore. Movement is faster than I expected and less clunky. I like the new upgrade mechanic. It isn't just a redone version of Hard Reset, but they thought it out logically. My only gripe is there is no multiplayer or coop and doubtful they will ever add mod support.
I said Flying Wild Hog was a studio to keep an eye on after Hard Reset. They are in a position now to put Gearbox and id software to shame.
