The developer Iron Tower recently released a trailer to the more combat-oriented spin-off from their intimidatingly hard RPG Age of Decadence.
Dungeon Rats will have a stronger focus on combat, featuring party-based gameplay, more essential positioning of units on the battle grid, skill point management, and more complications to satisfy any hardcore gamers. The game will be set in a prison complex ruled mostly by prisoner gangs.
Age of Decadence, released in 2015 was turn-based RPG with a very steep difficulty curve in combat, demanding attribute requirements for dialogues and essential choice and consequence framework.
