CorridorDigital, one of my favorite YouTube channels made a pretty awesome Portal-short. Instead of going the route of making their short based on the narrative of the game, they decided to make one of those basketball "trick shot" videos where all the shots are made using the Portal Gun.
The reason why I love this video so much is because it accurately portrays what I would probably do if I had Portal Gun. I mean, yeah, it'd be fun to traverse the world around me with portals but I think I'd rather try and figure out all the cool/weird things I could with the gun.
Other than playing weird games of basketball with the gun, I can't really think of anything else I would do with the Portal Gun. Actually, you know what? I'd probably never move again if I owned the thing. For example, the other day my PS4 controller was on the other side of the room and I couldn't reach it from where I was layingto start the next episode of [insert show that is endearing to watch alone] so I had to get up.
But if I had a Portal Gun, I could probably just shoot a portal to the wall next to the controller and another portal right next to me so I could reach in and grab it. I also probably wouldn't use doors if I didn't have to. Or maybe, if I'm trying to get a really nice shot of a city skyline, I think I'd use it to get up higher or get to a place that I'd probably have to climb to if I didn't have the Portal Gun.
Either way, though, this is still a pretty cool video and you should check it out if you have the time. I love these videos that show us what else we can do with items from the video game world other than what they were designed to do. If you had a Portal Gun, what would you do with it?
