I picked this up from a Mighty Ape daily deal for $20 on PS4. I really enjoyed the original Shadow Warrior from 1997 and this one seemed to have good reviews, so I took a punt on it.
I'm glad I did. As soon as the prologue chapter started I could not stop grinning from ear to ear. Big dumb fun doesn't even begin to describe it. I won't spoil anything, but lovers of 80s and 90s pop culture will have a blast with all of the references. It was worth the money just for the first 15 minutes alone.
Graphics are average for PS4 standards, but it controls well, and the story and humour are outstanding. If you're into shooters and are maybe sitting on the fence with this, do not hesitate, specially if it's on sale again. You won't regret it.
