Arknights is a free-to-play 2D fantasy strategy game. Take on the role of the amnesiac Doctor in the fight against a deadly infection taking over the world and recruit Operators to help battle your foes.
The game features tower defense-inspired gameplay where players deploy Operators onto the battlefield into strategic positions to defend points on the grid-based map. Place your characters onto the map to stop the flow of enemies towards your strategic points and unleash powerful abilities to help turn the tide of battle. Each Operator fulfills specific types of roles on the battlefield, but each character offers unique skills and abilities to make for a wide variety of squad compositions that deepen the gameplay.
