Our World is Ended is a Japanese science fiction visual novel developed by Red Entertainment and published by 5pb. for the PlayStation Vita in November 2017. Originally only released in Japan the game was later released by PQube in North America and Europe for the Nintendo Switch PlayStation 4 and Microsoft Windows in 2019. An extended Japanese-only version was also released earlier that same year for consoles. A sequel was announced in 2018 though no new updates have been announced since then. The game plays as a traditional visual novel largely entailing reading with limited player interaction. Player choice primarily comes in the form of the game's SOS (Selection of Soul) system; when at a branching point the game flow will pause and a number of dialogue choices will quickly scroll across the screen. The player must quickly choose an option which will change the course of the conversation. Not answering is an option as well though it generally incurs a negative outcome from associated characters.
