Murderous Pursuits is having a free play weekend.

So until August 8th you can trial it to see if you want it or not. For those who don't know Murderous Pursuits is basically a standalone of the Assassin's Creeds online mode no parkour bits though. You and a bunch of other people are assassins. You have a specific person you need to kill, other people need to kill you, there's a bunch of lookalikes around so it's not too easy. You get bonus points for how unexposed you are as well as the weapons will change points (so you can't just use the same weapon over and over without a penalty). It's one of those games that definitely looks fine if you get a group of friends together.
