Undervault is a role-playing game with random levels and perma-death. The game level contains rooms of different types (kitchen, bedroom, treasury, etc.). Some rooms are unknown and can be revealed with luck, or by using a room card. Pass through monsters, learn skills, get equipment and trade. Fight with hunger and fatigue. And most importantly plan dungeon carefully to succeed!


Undervault started as a small prototype that was made during a game jam in February 2016. In November 2016 Andriy Bychkovskyi decided to quit his job to develop the prototype into a full, commercial game. Originally the plan was to get it done in 3-4 month. But it took almost 1 year to complete, because of the lack of experience and limited resources (Undervault was done in solo). The game was released, and even despite completely failed marketing, got some attention and made some money. The biggest achievement was selection to Google Play Indie Games Contest final. In June 2019 Andriy announced that he is planning to rework Undervault with new graphics, game mechanics, and the story. The new game is called Ludopolis and will be released in 2020.
