Steamtown Challenge 100% in 13:56 (Poly Bridge 2 World 6c speedrun WR)

This is a World 6 Steamtown Challenge from Poly Bridge 2 100% speedrun WR This was a pretty big project, massive thanks to the grid budgeters community, as most of the strats in this speedrun are modifications to cheap grid solutions Q&A: Q: What the hell are these spring launchers, this is cheating A: This is called "SSR", or Stuck Spring Road. Basically we use springs to get the ROADS STUCK inside vehicles using SPRINGS, which makes them want to spin and fly really quickly. These are pretty sensitive, but if built right, they don't break and are not cheating. Q: Why does the Chopper fly in 6-05c, this is cheating A: This is called "Flip Cannon", which is based on the fact that the vehicles' hitboxes change when flipping, which can be abused to make them stuck inside roads, which the physics engine doesn't like and pushes them apart. These are pretty sensitive, but if built right, they don't break and are not cheating. Q: What the hell is the 6-13c strat A: This is called "SFR", or Stuck Falling Road. Due to the high falling speed, a road can get stuck inside a custom shape and makes it fly at ridiculous speeds. This is one of the only instances of this tech where it doesn't break Q: Where can I learn more about this tech? A: Join the Poly Bridge discord server! We are always happy to help! I am @polygrum on discord.   / discord   Q: I found a better strat! Where can I share it? A: In the Poly Bridge discord server, link to which is above, we have a speedrunning channel for that! Q: Your bridge didn't work when i built it! A: Check if you built everything correctly. Check the budget, hydraulic and spring adjustments. If the level is 6-12c or 6-16c, maybe you suffer from non-determinism - these strats mihgt not work every time, so either try to change them a bit or re-build the bridge from scratch. Q: This run is so slow how is this called a speedrun A: This is mostly to show the fast strats for these levels, I'm sure you could do better (please do!), though i do not want to invest more time into this category for now. Thank you for watching!
