Imaginary Games releases "Portal meets Mirror's Edge"

In case the title didn't make it obvious: I'm just kidding. However... Gentlemen, Ladies, I'd like you to imagine what such a game would look and feel like. You'd have all the abilities of jumping and climbing and turning around and kicking ass, plus the abilities of opening portals everywhere that's concrete.

Gentlemen, Ladies, can you see it?

...

Okay, maybe you can't. In that case, here's some help; Mirror's Edge from a Portal perspective, and Portal from a Mirror's Edge perspective

Now give Faith a portal gun and you have my dream game.

Another version

That title's not really obvious unless you look up Imaginary Games and find out it's not a real company. Since game companies sometimes do have names like that, and you could just be describing a game they're making without giving away the title in your title.

However, on the subject of such a game, it would hammer anyone with motion sickness about ten times worse than either of the source games.

And it would be about ten times as awesome. Low on health? Not feeling capable of kung fuing that machine gunner? Just place a portal beneath them headed out of a sky scraper's wall. Problem solved, in a nice, bloody, messy package.

Of course, if that's the solution most of the time, you have to create an incentive to go hand to hand. Many bad guys would be standing on some non-portal surface, for starters. Or, if you can't quite work the AI so they don't go haring off into portal-surfaceland, you set the portal gun with a limited but rechargable battery. Don't waste it on killing people, either use it for escape or as a melee weapon.

I just like the idea that you could fly across the city if you shot a portal at the top of the Shard, then jumped off the helipad at the top and shot another portal at the pavement. Weeeeeeeeee.
