CROSS OVERS THAT NEED TO CROSS OVER (Top 5 Friday)

"Alright, guys. I've been playing Mega Man X Street Fighter a lot lately, so it got me thinking: What other video game crossovers would be awesome if they really happen? So I came up with a little list of some fantasy crossover games that I think would be incredibly fun."

- Intro by Lasercorn

CROSS OVERS THAT NEED TO CROSS OVER is the 14th episode of Top 5 Friday, in which Lasercorn, inspired by Street Fighter X Mega Man, lists his five ideas for potential video game crossovers. It was released on December 28, 2012.

Description
Top 5 Cross Overs that we want to see happen with @lasercorn

Synopsis

 * 1) Half-Life 2 and BioShock: Gordon Freeman could be on the run from the Combine on a boat. The boat crashes and Freeman finds himself in Rapture. With only his crowbar, Freeman must make his way through the remains of Rapture while evading its denizens and the Combine. Lasercorn also suggests DLC including GlaDOS from Portal.
 * 2) Alien vs. Predator and Deus Ex: When two hostile alien races in the form of Aliens and Predators appear on Earth, only Adam Jensen is man/machine enough to send them packing. Lasercorn is a big fan of this idea.
 * 3) Mario Kart and Twisted Metal: The characters, items, and vehicles from Mario Kart could be featured in Twisted Metal, allowing such circumstances as Mario's classic kart being hailed with gunfire or Bowser going on a city rampage.
 * 4) Halo and StarCraft II: Wings of Liberty: Master Chief could find himself in the middle of a StarCraft battle and must search for a way home. It would likely be first-person shooter and Master Chief could team up with StarCraft protagonists like Jim Raynor.
 * 5) Left 4 Dead and Borderlands: Two titles who use four-player team mechanic in different ways. The story could involve a Vault being opened, releasing a zombie virus that the Borderlands protagonists must fight, featuring enemies from both franchises.
