>>> The Eternal Abyss is a very difficult game with little-to-no handholding. Losing progress and raging is a part of the game which should be expected. <<<
This game houses towers that intend to push the limits of difficulty and human capability. Do not expect to have an easy time with the content provided in these areas.
There are also numerous branching areas from The Eternal Abyss with different styles of towers such as Pit of Misery & Timeless Manor, with more to come.
You can practice the towers in personal servers or if you own the "Personal Servers & Practice" pass.
Originally a reiteration of Pit of Misery from Eternal Towers of Hell.
The goal is to have 50 towers in each area of the game.
