The two player local co-op action game Twisted Metal, featuring brutal car on car action, is on sale today over at  Amazon for only $39.99.  While the co-op felt a bit lacking, overall the game was a solid experience.  Now that it's at a more affordable price point it might be worth checking out - especially if you are a fan of the series.

One of the more popular ways indie devs are getting their games out there in front of an ever growing audience of gamers is to team up with a few other developers (some might say they are cooperating) to offer their game as part of some form of bundle deal. GamersGate.com is offering their own indie game bundle, the IndieFort, starting today and going until next Friday, and in their bundle there's at least one cooperative game that caught our eye: Wanderlust: Rebirth.

Starting today you can snag Trine 2 on Steam for 50% off the normal price of $14.99.  The three player co-op game is available in a regular version for $7.49 and a Collector's Edition for $12.49.  The CE includes a free copy of Trine, the soundtrack to Trine 2, and a digital art book from the gorgeous looking game.

Amazon's deal of the day today is Gears of War 3 available for the low price of just $29.99.  It's a title we felt was one of the best games available last year, giving it an Editor's Choice as well as awarding it our Co-Op Game of the Year for 2011.  With four player campaign co-op and five player online Horde and Beast modes, as well as plenty of couch and online options we couldn't help but fall in love with Gears 3. 

It was only last summer we showed you the process of renting games from a RedBox kiosk.  Hopefully a few of you have gone out and given it a try - it's a good way to check out a game for a relatively cheap fee on a whim.  If you haven't actually done it, perhaps this week you will.  Why?  They're offering one night's free rental.

Amazon continues its streak of solid deals on downloadable PC games.  This time in their "Farewell to February" sale they have a handful of co-op titles for some low prices included the recently released Darkness II and last years hilariously awesome open world game, Saints Row the Third.  Both of those games are only $25.

Right now Amazon has Xbox Live Gold subscription cards for $35.99, a discount of $14 off the normal price of $59.99.  If you play co-op games online, you'll need an XBL Gold subscription to do so, as it is a requirement of Microsoft's network.  The subscription also gives you access to things like Netflix, Hulu, and ESPN 3.
