Awesome game! I really recommend getting this one, especially when you have an Xbox controller. It's a UPlay redeemable key.
Easily one of the best platformers of the current gaming age, it looks amazing and plays even better - now on sale on GMG at 75% off (you can even make it cheaper by applying the extra 25% off voucher below!). Get it because it's funny, too bad it has no online cooperative mode :( The voucher code is: SEPTEM-BEROFF-ER25XX
