Remember, this is Machinima (the site, and the titular genre), not a mod. So sit back and enjoy, you can't literally play this. Although it's hard to do so without imagining the impossible turbo tunnel level done in Source.

Pretty shrewd how the level's creator (M0rtanius) staggered the platforms so you could shoot up foes above and below you, just like in the 2D version. But I'm guessing this isn't one-hit-kill difficulty.

Thanks Awwal for sending the tip. Sorry we spotted it so late.

Giant Bomb community member buzz_clik threw theses screens together in lieu of an actual game after reading a story about the Rutgers University robot that conquered the Atari 2600 classic game. It would have been cooler to have an actual flash game, of course, but what buzz_clik lacks in programing know-how, he (or she) makes up for in Photoshop skills.

And I can't argue with buzz_clik's logic on this — the games do seem to be a match made in heaven. Or, post apocalyptic brown heaven as the case may be.

Why not make a game that combines Pitfall! and Fallout ? They're both open-world games, with our hero braving a harsh landscape looking for stuff to pocket. They both have portions that take place underground. Both games have scorpions, as any good game should. Hell, there's even an expansion for Fallout 3 called The Pitt!

So very well played. But wait, there's more! Hang on for the testimonials at the end. Audio possibly NSFW.

Just more proof that it hasn't been parodied until it's been TF2ed.

It's already been 20 years since the release of the first Super Mario Brothers and to celebrate, Generation Productions has got an internationally acclaimed composer named Winifred Phillips to record a new track in tribute, called "Go Mario!". The song will be featured in a cd called, "The Best of the Best of the Best: A Tribute to Game Music" that will be only be available at Game Music Central starting May 1st.

Ok, it's totally geeky, but I'm hoping it will make a killer 80s mash-up with a Eurythmics song in the future. Is there a DJ up in this house? Kim Phu

WORLD OF WARCRAFT MARIO LEVELS. [The Last Boss - Thanks Andrew!]

Wow. I don't even know what to say after watching this one. It's in turns terrifying, disgusting and downright hilarious. This goes beyond the normal mash up, this is like a mash up on acid. A semi-pornographic Zelda parody done in South Park animation style using the voice tracks from the Zelda cartoon. And to top it all off , it shows the original cartoon the voices come from in the lower left corner. Amazing job by Robotbling! I'm speechless... Flynn De Marco

Some very patient soul put together a hot little mash-up of Jay-Z's 99 Problems with Final Fantasy VII's Weapon Raid. The end result has the JZ song dubbed to the beat of Weapon Raid. Hotness. Brian Crecente

A surprisingly well done mash-up of Doom and Guild Wars shows how the God features for the Dervish class will work. Needs more gibs and no two minutes video should ever require half its length to accommodate the end credits. Florian Eckhardt

Manga, anime and PS2 game Cowboy Bebop dubbed with dialogue and music from Grand Theft Auto: Vice City. Everything syncs up perfectly as if were a real movie! Like, I'd actually watch 90 minutes of this. Brian Ashcraft

Super Mario Bros. seems to be the default setting for hackers looking to mash games. This clever Legend of Zelda hack actually does a good job of blending Mario and Link's universe in an non-annoying way. That's what these mash-ups are becoming, you know. Brian Ashcraft

Man, we wish we could steal this in good conscience and just embed it for you. But you'll have to take our word for it: click the link below to go over to Destructoid and see this excellent mash-up between Michael Jackson's Moonwalker and Super Mario Bros..

Jacko's wonderful moonwalking powers just kick the crap out of Mario's. I would pay for this game. Florian Eckhardt

Skater-wear outfitter Magical Mosh Misfits is peddling Mario in its Summer collection. "Super Magical Bros." tees feature a cyclops plumber with skateboard. There are "Magical Bros" caps as well, which come in MaXXo, LuXgi, WaXXo and RockmaX (correct letters deleted to avoid a lawsuit). The lids have a special pouch to hold cigarettes.

Yes, people still skateboard. At least in Japan.

In a duel to the death, Mario faces off with a giant Colossus. He sends a red Koopa shell in for the kill and...

...picks up a 100 points.

Neo's got nothing on Mario in this fan-made Matrix Reloaded Mario mash-up.

It's not Jay-Z meets Weezer mash-up, but Ogle Earth points at a way to mash images from games together. The tech at OGLE (OpenGLExtractor) "observes the data flowing between 3D applications and the system's OpenGL library, and recording that data in a standard 3D file format." Basically, the tech allows 3D images from different sources to be formatted the same and then, integrated with each other. To continue with the mash-up reference in the first line, it'd be like modulating the key a song was in, so that it'd work alongside another song. Or something.

Modder Seth Fogie took his Xbox 360 and stuffed it inside an Atari 2600 shell. In a detailed how-to, he lays out the process step-by-step. As cool as his mash-up is, I just wonder why he choose an Atari 2600 — a system that was eventually overshadowed by the NES. Is this some sort of biting console commentary? Probably not.

"For those who are wondering," Fogie writes, "the Xbox 360 did turn on and stayed on for a few minutes before it overheated." Guess you can take the 2600 out of an Atari, but not the 360 out of an Xbox.
