You play Whisper Mountain Outbreak as one of Fear & Hunger 2: Termina's contestants. Termina's moon waxes over the mountain, and its monsters crawl out among the zombies.
You need both games installed. Everything from Termina is read from your own copy while you play, and nothing from either game is included.
What you get
Play as a Termina contestant. Pick Levi, Marina, Daan, Abella, O'saa, Marcoh, Karin or Olivia. Each is drawn with their own Termina walking sprites and portrait, and their Termina starting gear sets their stats: armor raises max health, the weapon raises melee damage and magic defense raises the mind (sanity) meter. Press F6 in the lobby to choose.
Termina's monsters in the outbreak. Some zombies turn into Moonscorched, villagers, ratkin, woodsmen, janitors, headless beasts, riflemen, owl cultists and, under the full moon, the Crimson Father. Each one is built from its own Termina limb sprites. Its health and damage are scaled from its Termina stats, and it uses its Termina cries.
Termina's limb rules. Hits can cut limbs off the Termina monsters. Losing the head kills a humanoid outright, losing an arm weakens its attacks and losing a leg slows it down.
The moon phases. Each mission starts at a waxing crescent, and the moon grows every four minutes until it's full. Each phase shows a frame of Termina's moon-rise and plays its bell. The fuller the moon, the more zombies turn into Termina monsters.
Solo only. The Termina changes only happen in Solo games. In online lobbies the game stays unchanged.
