Annihilation is an Infinite Mode achievement in Run 3, found in IM 41.
Jump immediately after you land on a platform. This saves time as you need to get through every platform as quickly as possible.
Depending on which character you happen to be using when you reach IM 41, you could breeze through destroying the tunnel. If you happen to be using any of the characters in the suggested characters list, you will have an easy time getting this achievement. However, if you are using, for example, the Child or the Skater, it is impossible to get this achievement, due to their very long jumps and fast speeds (for the Skater).
Remember, do not save the platforms to guarantee that you will have something to land on near the end. If you do this, you will run out of time to make it all the way around the tunnel and destroy everything.
