Humble Bundle is giving away free copies of Shadow Warrior. Looks like you've got to claim (and possibly redeem) your key before noonish C.S.T. Saturday.
Shadow Warrior is fun as hell, and it's free again for one day. Go get it on Steam. http://store.steampowered.com/app/233130/Shadow_Warrior/
The main character's name is Lo Wang (awesome). Which leads to great voice lines such as "You mess with the bull, you get the Wang." Graphics are a little dated (of course) but gameplay is fun and it's loaded with 80s cheesiness. Kind of like Big Trouble in Little China.
I had more fun with this than I've had in a long time. Immediately after beating it on normal difficulty, I continued on to replay in hard mode. That's right, hard Wang. The sequel is definitely on my wish list, hoping for a cheap deal during the winter sale.
