Ubisoft has been around for 30 years, and they're celebrating with free stuff.
The publisher will be giving away one free game a month for the next year, and they're starting with some quality stuff. Right now you can get Prince of Persia The Sands of Time for free - just click here.
Sure it might be a little old - it came out in 2003 - but the blend of platformy puzzles and combat has been hugely influential and anytime you've run along a wall in a game it's pretty much copying this classic.
Plus the dreamy graphics haven't aged as badly as you might think.
These games will only be on PC so you'll have to battle a bit with Uplay (which is better than it used to be). A new game will be announced in July 2016.
