An insect army has invaded the Northern wilderness and taken the tamarin's family. Tamarin is a 3D action-adventure game developed by Chameleon Games—a studio founded by former Rare developers—featuring a tamarin monkey navigating an interconnected open world across forests, fjords, and mountains. Platforming and twin-stick shooter sections alternate across the campaign, with the tamarin rescuing birds, chasing electrical fireflies, and uncovering a secret underground world of ants as it pushes deeper into insect-held territory.
