From Press Release:
Coatsink have today released a free Halloween themed content update that gives a creepy twist to their otherwise cozy minimalist city builder, ISLANDERS: New Shores. The update, available now on PC, PlayStation, Xbox and Switch, adds the “Halloween” biome – a dark and gloomy map that contains a creepy secret, so be careful where you click!
The new update also adds a new Boon called “Replace”, the addition of pumpkins, gravestones and candle variants as Seasons items, a new camera filter and a new building facade to unlock for the Aviary building, both unlockable via new challenges. You can find a full list of what’s in the update below.
