Universe Prison

Universe Prison is a 2D random-dungeon RPG set in a dark fantasy world in the far-future reaches of space. You try to escape the vast Universe Prison, a dungeon spanning 10 dimension floors, where evolved human life forms confront the ruler of the universe. The prisoners were once defeated and imprisoned; whether they can escape is the central question.

A dungeon that changes

Each run randomizes the playable character, enemies, party members, maps, items, equipment, shops and facilities. You start as one of 16 character types. The 46 enemy types appear in randomized combinations, levels and enhancement types, while facilities are placed randomly, shops have changing assortments, and party members are encountered at random.

Items include 51 types of consumables, 35 types of weapons and 36 types of armor, with rarity ranks from 1 to 4. The dungeon offers different challenges on each run; if everything goes exceptionally well, a run can reach an ending in 5 to 6 hours.

Turn-based battles

Battles use turn-based command selection and begin when you encounter an enemy symbol on the map. The HP, ATK and DEF of every battle member are displayed in real time to inform your tactics. Each playable character has different abilities and skills, and characters can sometimes learn special skills as they level up. These include consecutive attacks, an attack that deals 10 times damage, a powerful attack that ignores DEF, a final attack that consumes all HP, doubling maximum HP, making the whole party invincible for several turns, and summoning a powerful party member.

Some skills and items marked with a star can be used without consuming a turn action. Continuous attacks can also let you attack repeatedly and win without giving the enemy a chance to respond.

Survive the floors

The game is designed for repeated attempts and has a high difficulty. Your character begins close to death, and HP and SP do not recover automatically, so you need to manage how you restore and maintain them. Each of the 10 floors has a time limit: explore, collect items and equipment, and move to the next map before time runs out. Some enemies are too strong to defeat, and a party member who dies disappears permanently. A larger party has an advantage in battle, but each character gains less EXP.

On the map, you move around enemy symbols, whose strength is shown visually. A real-time countdown runs during exploration, and the game ends when it reaches zero.
