Normally they land with flaps down, which reduces landing speed.

I've heard sometimes landing gear is also involved..

We really need a placebo controlled double blind study to learn if landing gear is actually effective of just a cargo cult like parachutes.. [0] https://www.bmj.com/content/363/bmj.k5094

Gears also aerobrake.

There were no flaps deployed. Without flaps it's going to be a lot faster than a normal landing.

Yes, it was a very fast landing.
