No, seriously. I was a bit disappointed that this lauded video played it safer than a traffic instructor playing bumper bowling with a lifejacket on. I wanted more wild speculation, so that's what I'm going to provide here myself.

First off, let's return to an important source of information the internet has seemingly forgotten about: the interview with producer Tom Farrer. Perhaps the most important thing he notes is that your character builds momentum, and that reaching your maximum speed can't happen instantly. Here we can contextualize what the trailer analysis calls a "sprint" as the maximum speed you achieve by running for a certain period of time, signified by the peripheral motion blur. I would assume therefore, that there is no "run" button, and that you can keep up your sprint until you have to climb something or reach a dead end. Farrer notes that any weapons you pick up will hinder you, so I'm assuming anything more than a pistol will make sprinting impossible. It's also likely you will only be able to carry one weapon at a time, and since Farrer says the number of bullets is limited, you may not even be able to reload your weapon.

Farrer hints that any brightly colored objects can be used for your free-running stunts, and judging from the footage, I would say that it isn't just red objects, but also orange, blue, and green ones, like the blue ramp and the orange wall we see Faith run across, that can be interacted with. There are some green objects seen below Faith in the scene where she is hanging on a railing and looking down.



Another thing he mentions is the inspiration of Prince of Persia, and I think that will inform a lot of the gameplay elements in Mirror's Edge in terms of context-sensitive controls. The way faith jumps and instantly vaults over the fence in the beginning of the trailer suggests that for the sake of intuitive gameplay, there is no separate "climb" button, and Faith will do this automatically.

In combat, Faith often uses her legs to attack, and can disarm foes this way. However she can melee with a gun in her arms as well. There appears to be one button for leg attacks, and another for arm/fist-based ones, which turns into a pistol whip or rifle butt if one has the relevant weapon in hand. The sheer variety of leg motions might mean that moving the analog stick in conjunction with the kick or punch button can result in different attacks.

In conclusion, I would expect the controls to be set up accordingly:

Face Buttons: Jump, Crouch/Slide, Punch, Kick

Trigger: Shoot

There would also have to be a button for dropping the weapon, but it's hard to say what other functions that would share, or where it would be on the controller. If there's no aiming reticule, does that mean there's auto-aim?

Lastly, Farrer's constant references to the game's linearity reveal more possibilities. He says "we want to move you through it," and mentions there are no sidequests, but also reassures us that "there's a lot of choice within the different routes and paths." I would expect the flow of the game to be like Prince of Persia, although slightly less linear. While there could be different paths, they would all lead to the same save point eventually. I also expect the game to be set in one continuous world with no separate missions or levels, but some distinct areas.

What do you all think?
