Knockout City

This can be tricky in terms of timing If you are going for a catch from a full charged sniper shot. However you don’t need to catch a fully charged one, simply catching a non charged one will do. I caught a non charged shot and the achievement popped.

Given all achievements in this game are a little buggy I would appreciate if others can confirm this guide in the comments.

The timing on this is going to be very strict, because the Sniper Shot ball is very fast when charged. You'll notice when someone is using it against you because it has a laser that points at you, and takes a second or two to charge.

Because the catching is kinda lenient, you may be able to get lucky and start the catch right before it's thrown and still catch the ball but the easier way is to try and get someone who's farther away from you to throw a Sniper Shot at you so you have a bit more time to react to the throw. Not much more can be said, just get someone to use it against you and either spam catch in the hopes of getting lucky or try your best at reacting to the throw.
