This is a mobile port, APK format, of Fear & Hunger 2: Termina for Android devices. It's not official, so it may have some bugs but it's the full game and it's 100% playable, even offline.
Fear & Hunger 2: Termina, released on 9 December 2022, being the sequel to the indie survival horror RPG Fear & Hunger. Developed and published by Miro Haverinen.
A mix of jRPG and Survival Horror. Turn-based combat meets resource management, the game takes place in the same universe as the original Fear & Hunger, but it is a stand-alone story and no prior knowledge of the series is required.
You are presented with the story of 14 train passengers, 8 being playable, forced by a malicious entity known as the Trickster Moon God to become participants in the Festival of Termina - a battle royale kind of event where only one of the participants will come out alive.
