Basically title.

To do it, bind Jump to a MWheel direction (I used MWheel Up since my MWheel Down is bound to Crouch for Floor Clipping), then sprint, jump, hold Crouch while in the air, and use your MWheel Jump as you get close to the ground to bounce.

If you have speedrun Half-Life 2, this will feel very similar to the input needed for Accelerated Back-Hopping.

You MUST have Crouch set to Hold and not Toggle for this to work. If you have Crouch set to Toggle, you'll just stand up as soon as you jump. I also found I was no longer able to Floor Clip with Toggle Crouch, so you probably don't want to use it, anyway.

Also, you CAN preserve momentum by jumping as soon as you hit the ground. I confirmed this in the on-foot sequence near the story end. The Jump-Pad-like things that launch you from one section to the next move you at higher speeds than just sprinting. By crouching and using MWheel Jump you can preserve this momentum. With this being the case, it might be possible to build up speed using airstrafe or similar tech.

I do feel I need to note that keeping this going feels really tricky compared to other games with similar movement tech - like ABH/ASH in HL2 - particularly when trying to move uphill, even just slight slopes. It's possible this is just a skill issue, though, and I'll keep practicing it.

It is also possible to scroll too quickly and you end up just jittering and losing speed. I have a Logitech G903 mouse that allows you to unlock the mousewheel and let it spin freely. Trying to just unlock the wheel and spin it rapidly resulted in the jittering I mentioned.

Heya, thought I'd get a routing / theory-crafting / general speed tips thread going.

So far I don't have so much of a "route" as a general game plan. Some of these things are going to be REAL obvious to anyone who has done speedruns before, but still included as reminders.

Some of these can be ignored for any% unrestricted where you don't need to care about damage, fuel, battery, etc

• Do objectives immediately instead of exploring / farming
• If no marked locations for Story missions, explore toward known Story locations
• Minimize time spent scrapping / looting - know what you need and don't farm beyond that.
• Also, learn the best ways to farm the things you do need.
• Health and Durability are resources - spend them wisely.
• The only HP that really matters is the last one.
• Minimize research beyond what is needed to progress the story

Research to rush:

• Offroad Tires - Far better than Spares, generally more useful than Summer Tires, you can even research these after the first mission.
• Matter Deconstructor - Need for Dumpster Pearls
• Liberator - This can get Armored Doors and Panels from Squires far earlier than research. They need 5 Sap to craft, feasibly farmed from Tourists.
• Hand-Vac - Far quicker for picking up scraps, NEED for Marsh Eggs etc
• Turbolight Engine - B/c the Carbureted Engine is WEAK. Don't bother farming 40 Sap from Tourists, probably won't be able to craft this until Mid-Zone.

Research to consider:

• LIMpulse Emitter - Keeping grabby Anomalies and Bunnies off your car can come in clutch.
• Resource Radar - Locates resources but also valuable vehicles like Squires, Investigators, Box Trucks and Fuel Tankers. I slept on this until late in my normal playthrough.
• Any Extra Fuel Capacity - Fewer refueling stops on the road means less time spent refueling.
• Any Passive Battery Recharge - Seems more efficient than crafting jumpers in the long run, but if you aren't using abilities or leaving your headlights on, maybe skip this. It DID prove very useful on the mission with the LIM Shield, though
• Storage additions seem like a waste but I need to see how painful it is when trying to finish a run without any. Maybe useful for storing extra parts picked up w/ Liberator
• Re-roll / Junction Skip - pretty-late-game but obviously useful, gets better with antenna upgrades for more charges
• Matter Regenerator - Parts stored here will be fully repaired after returning from a run. Cuts down on mats spent on Putty (chemicals!) or fixing status effects.

--- TO-DO LIST ---

Actual Routing Stuff

• Minimum mats needed for mandatory research / upgrades at each stage
• Best spots to go when no story objective is marked
• Best farming methods for needed mats
• Is it worth it to grab Anchors beyond what's needed for the gate to speed up research?

Ongoing

• Document useful glitches / movement tech / skips
