This great re-imagining of the iconic Nintendo Entertainment System shows just how darn useful a Portal gun can be- in pretty much any situation.
I think it's pretty evident that the addition of a Portal gun into any experience that, you know, didn't revolve around creating portals would be a literal game-changer. But it's fun to imagine some of them, isn't it?
Asteroids: Create a couple infinite looping shot. You never have to move or spin out of control. Just don't get in the way of your own shots.
Pac-Man: Ghosts got you blocked on both sides? Not anymore they don't!
Street Fighter: Hadouken your opponent from behind while facing them.
TMNT: Turtes in Time: Heroes in a halfshell- Turtle Portal!
Tetris: Don't know where to put that piece? Give yourself some time to think.
What do you all think? Any other amusing examples?
