Loop Hero is a 2021 roguelike video game developed by Russian studio Four Quarters and published by Devolver Digital.

Landscape cards allow the player to place various terrain features around the hero's path, such as mountains, meadows, forests, and buildings.

[1] The game begins after the world has ended, with the introductory dialogue explaining that an evil lich obliterated reality and all of the things in it.

The hero battles and is able to defeat Omega, and it is revealed that one of companions, Yota, was actually the Goddess of Probability who has been secretly aiding him all this time.

Defeated, Omega congratulates the hero and explains that it will take a thousand years for him to reincarnate back into Alpha to create a new universe.

The earlier prototype idea worked well to the theme, though the final game they produced for Ludum Dare did not win as it wasn't very polished.

Four Quarters recognized that they had the foundings of a good game, spent more time with the Ludum Dare version and were able to secure Devolver Digital for publication and support.

[9] Following the Russian invasion of Ukraine, the developer encouraged piracy of Loop Hero in countries where sanctions prevented purchase.

[22] Evan Lahti, writing for PC Gamer, enjoyed the surprises that different card combinations could create, although he thought the lack of new ones hurt the later game.

[5] Sam Machkovech of Ars Technica enjoyed the game's take on the idle genre, and how the player had to make difficult choices on their abilities.
