You play as Low and Alone, best friends since they found each other in this lonely nightmare. Each has their own iconic item: a bow for Low and a key for Alone. By working together, they have become experts at sneaking through hidden passages, lifting each other over huge obstacles, and watching out for one another.

Whether you play with a friend or an AI companion, you will rely on each other's iconic items to create opportunities and progress. The environment is full of elements and possibilities that imaginative children can take advantage of. Low's arrows can reach high targets, cut ropes, or take down flying enemies, while Alone's key is perfect for crushing helpless enemies, breaking obstacles, or operating huge machines.
