What we know about the new "Reverse Mods" in Quickplay 2

Heads up; new Quickplay modes just dropped!

TETR.IO version β1.5.0 introduced "Mod Mastery" which rewards players with new "Reversed Mods" after 30.000m is reached on each normal one. These mods are meant to be the "final bosses" of their respective mods and are not meant for most players, as evidenced by their high difficulties. Reaching floor 3 in all reversed mods rewards players with the special "Harbinger" achievement.

Read on to learn about the new mods and be prepared!
