See Left 4 Dead fan-made mod 'Mushroom Massacre' in action

Remember that Mushroom Kingdom mod DoritoClock was working on for Left 4 Dead? Well, he's making progress and now has some new areas of the campaign to show off: the exterior of Peach's Castle and Super Mario 64's first world, Bob-omb Battlefield. He even added the latter's Chain Chomp!

It seems DoritoClock has also been reading our diary, because he's compiled a 10+ minute video walkthrough of all the areas. You can find that video past the break, but if you're anxious to see that Chain Chomp munching on a few undead carcasses (like we are), prepare to be disappointed. It's a work in progress, folks.
