Mega Man 11 Out Of Bounds (OOB)

From Discord - How do you get out of bounds (in Acid Man)?

The one in Acid specifically is a long one. You use Rush Coil to get some height, then you use the Pile Driver to hit the wall. The recoil pushes Mega Man upward. At that moment, you go to the weapon menu and select another weapon, this lets Mega Man switch back to the Pile Driver and fire again before falling down. This process is repeated until you get enough height.

When Mega Man stops colliding with the wall, he is officially out of bounds. Then it is just a matter of using the correct amount of Pile Drivers to move forward to skip some rooms without going too far. The Bounce Balls are then used more for a timing and consistency strat. If done correctly, Mega Man will land on the last water room. If he dies you failed to position him in a location where the game can detect him.

I would add, it's not zips like NES games, gravity still affects Mega Man normally. If he gets too far away from the camera he actually dies. So there's a balancing act between getting ahead and bringing the camera along for the ride.

That's why you don't see OOB tricks in stages like Tundra or Torch. Its entirely possible to get OOB in both, but it's not really possible to save time with it.
