Don't intend to speedrun this really other than getting that currency stuff with the bioweapon shit.

You can traverse interiors and otherwise foot limited areas pretty quick with the reload speed boos shoes and the revolver, if you could also find something that hampers reload speed that may also be helpful.

I can't test it right now but Deln said he found you can reload, switch weapons, reload. I'm not sure how well it works but could be something to test

i utilized reload, swap to sidearm and back, reload with nail gun to have fast movement speed until i got the full parkour set :) Does the revolver offer any additional speed bonus or something i missed?

Hello from the future :) Ubisoft have since added an ability to switch ammo types with a hotkey, which is way more efficient than having to fire the gun to reload, and actually makes this technique worthwhile, somewhat.

Munitions boots give a +40% speed boost to your base speed, while parkour kicks and strap will give +15% and +17% (straps only when the gun is holstered), so a total of only 32%. So if you can use the munitions boots effectively, they are faster.
