Undervault is a roguelike with all the typical ingredients of the genre: a very high difficulty level, permanent death, complex skills system, and turn-based combats. All this in a setting that's different from what you're used to seeing.
Before starting to play, you can choose between two difficulty levels and various character classes. In Undervault, you're not going to find warriors, wizards, thieves, etc. No, here, you play as a chef, monk, bandit, entrepreneur, and more. And of course, each class has its own characteristics and unique abilities.
To move from one room to another, you just have to tap the new room where you want to go. If the room is empty, you can loot it directly; but if there's an enemy in there, you have to deal with him first. These combats are turn-based and you can aim at any part of an enemy's body to injure them. You need to be careful, though. If you're character dies, it's game over.
Undervault is a really original roguelike, with a different concept than most titles from the genre, while still maintaining the basic essence. In other words, the game is difficult and demanding, so you'll need strategy, ability, and a little bit of luck to make it through.
