Ginger kids, old people, underpants gnomes and other general threats are invading South Park Colorado. It's up to Kenny, Stan, Kyle, Cartman and other South Park kids to keep the evil at bay with their snowballs, special abilities, and a variety of defensive towers. We gave this game a co-op whirl, curious to see if South Park: Let's Go Tower Defense Play! is worth an 800
purchase, or if it's best left in the snow.
'Splosion Man swept us off our co-op loving feet this summer. Now, Twisted Pixel, the studio behind 'Splosion Man, has teamed up with Omaha Steaks to bring you a very - er - interesting sweepstakes. Play 'Splosion Man, win Filet Mignon. Seriously.

We waited, and waited, and waited for Trine to finally make the leap from the PC to the Playstation Network. A bit late with a quiet release, we finally saw the 3 player co-op title sneak it's way on the Playstation Network. While many of us were happy to see the PSN version of Trine finally come about, we have some disappointing news.

Upcoming top-down Alien co-op title Alien Breed Evolution has been confirmed to be released episodically in three installments, instead of being the first of a separate trilogy as previously believed. It's said that each of these three episodes will take players 5-8 hours to complete, and will be available for download "December-ish." If you're unsure about paying for 3 separate installments of the game, don't fret - the prologue will be available for download and preview for free.

While Dragon Age: Origins is a single player gaming experience, BioWare is taking steps to make sure players can still connect and share their game together. The PS3, Xbox 360, and PC versions of

Have you ever been tempted to experiment with little pick-me-up out in the Borderlands? Say you're wandering around the Arid Badlands when a horde of goons surround you. It feels good to berserk just a little, doesn't it? We're here to tell you it only takes once to get addicted to Berserkeroids, and it takes all the friends you have to help you through the ups and downs that follow. This is the tale of an overdose of Berserkeroids, as Nick aka Brick had one too many hits, and tragically could not stop running.

You'd be daffy not to take advantage of this
Today is the day that Fairytale Fights hits store shelves in all it's brutal glory, and the team would like you to enjoy a bit of DLC for free for a short time. This free DLC will include 4 new playable characters, and 3 additional PvP arenas on both the Xbox 360 and the Playstation 3 versions of the game.
In order to get this otherwise $15 DLC for free, you have to register your copy of the game here - no cheating guys, this is actually a pretty cool incentive for those that purchase the game. After the 90 days, the DLC will still be available, so no one is completely left out.

A recent job listing at EA Games briefly mentions a next-gen Boom Blox, which we happily file under the "rumor slip-ups" list. EA's job listing, direct from the official Boom Blox team asking for an additional programmer, says;

The Marvel: Ultimate Alliance 2 character list continues to grow, this time adding Deadpools occasional partner in crime, Cable. Cable will join Carnage in the latest DLC Pack. We're going to call this the "C-pack," and pretend it stands for "Co-op."
The announcement continues to confirm our the DLC leak we reported on a few weeks back.
A college student bound and determined to show Shakespeare and E. Allen Poe who's boss, Katrina tends to focus on the important things in life. "Important" in the eye of this beholder, covers anything from gaming to reading comics or novels, to fencing and hanging out with awesome people!

She may be caught including pop-culture references in her writing, as she enjoys a wide variety of geeky pleasures.
