Mention the word zombies in a room of gamers and two franchises instantly come to mind. Resident Evil and Left 4 Dead. While other zombie franchises have tried to claw their way to the top, these two from Capcom and Valve respectively sit atop the zombie food chain. With Capcom’s recent affinity for crossing over franchises with other publishers, it is great to see that they have come together with Valve to enable the Resident Evil 6 x Left 4 Dead 2 project.

In a completely free download, Resident Evil 6 PC players will be able to experience a new mode, “The Mercenaries No Mercy” featuring Left 4 Dead 2’s signature cast – Coach, Nick, Ellis and Rochelle – as playable characters. Each will have a custom weapon load-out for the mode. Also making their debut to the Resident Evil world alongside the foursome of survivors are going to be the Witch and the Minitank. This mode will be going live on April 5th.

Far-gone are the days when networks held enough power and importance to have TV crossovers and intermixing story lines, much like the days when George Reeves would pop up on I Love Lucy or story lines interweave between Buffy and Angel. Fox seems to be the only network with interest in doing such stunts, as Family Guy’s Stewie popped up on an episode of Bones.

Well, it looks like Fox is doing it once again with an announcement for a Simpsons on-air scavenger hunt in celebrating 20 years of broadcasting TV’s favorite animated family. In a press release, the network announces that it will start on November 9th, and go for an entire week.

FOX is paying “homage” to 20 years of television’s favorite yellow family with the network’s first-ever on-air scavenger hunt. Beginning Monday, Nov. 9 and continuing through Friday, Nov. 13, fans can watch FOX each night to find SIMPSONS shout-outs, tributes and clues featured in primetime programming and on-air promos.

One lucky winner will receive the ultimate SIMPSONS prize package, including a trip for two to Los Angeles to attend a SIMPSONS table read with the Emmy Award-winning voice cast and producers, a home entertainment system, SIMPSONS DVDs and merchandise and tickets to Universal Studios Hollywood, home of The Simpsons Ride.

Anybody over the age of 13 can participate, and once they catch the shout-out, be sure to visit www.fox.com/scavengerhunt each night to test their knowledge and download some pretty cool Simpsons goodies. The contest officially starts after next week’s episode of Simpsons, so be sure to keep your eyes peeled!
