So this post is about giving y'all hints about how the movement system works so you can abuse it for your own runs. This is not a complete list (see point #5) and there are probably more exploits I haven't discovered myself.

1. CLIMBING IS YOUR ENEMY. The game will lock you into a canned animation which will stall your momentum. Vaulting will retain your momentum (added in the v1.0.1 patch), but from my testing it's still slower than just running forward. 1.1 It is possible, with enough training, to reliably jump over waist-high obstructions when running. It's not pixel/frame perfect but it's very close to it. It's hard to describe how to pull it off but it's basically up to intuition and understanding the game's physics.

2. Conversely, WALLRUNNING IS YOUR FRIEND. Wallrunning has zero friction and grants you a massive speed boost when you first latch unto a wall. It is possible to pull a perfect wallrun reliably every time - if you're familiar with the original Mirror's Edge, it's basically the same mechanic.

3. SLIDING. Sliding immediately doubles your speed, then over the course of about half a second, reduces it down to zero. By carefully exploiting this system you can effectively spam your way into short speed boosts.

4. STAIRCASES. Harkening back to Mirror's Edge, spamming jump + forward on staircases will give you a nice speedboost at the cost of limited strafing.

5. There are explicit hidden paths created for speedrunners in some set-pieces but I'll let you figure them out. I will hint that it is possible, though hard, to land right on top of the fallen comms tower in the final set-piece. It can be done reliably, and is slightly easier in the v1.0.2 patch.

Good luck mates! Hope you have fun.

After a few tries I beat current WB and my own PB. A sub 2:30 run is def possible

"I will hint that it is possible, though hard, to land right on top of the fallen comms tower" you mean land from falling off the airplane?

^ ok i got it once,, landed really far.. at half of the tower.. still ha no idea whats the strat

Some other tips:

• Sliding at the edge of a ground also gives you a speed boost. I use it to get more speed for Wallrunning.
• If you jump at the right moment when Sliding you can jump a bit higher than normal. Hard to get the timing right, up to intuition.
• Try to be on air after Sliding when you can. From my understanding you can Slide twice before cooldown, jumping after that retains your speed and momentum than just walking. That's pretty much the new things I noticed, will write again if I noticed something new :D

@LA-Volpe

Great tips. Also, finally, I understand why people can slide in midair! After all these months! I could not for the life of me understand how people do it up until now. Thanks for that lol.

My debugging rule of thumb is that if the bug doesn't hinder casual play, can only be found by abusing the engine, and is beneficial to speedrunners - I'm gonna keep it. So until it's proven that this bug softlocks the game or frustrates people just playing to the end, feel free to abuse it
