Arknights is a free-to-play tower defence mobile game set in the dystopian, post-apocalyptic future setting of planet Terra. People on the planet show kemonomimi features and have animal characteristics or mythological races.

The in-game natural disasters have left behind a valuable mineral, Originium, which enables the use of a magic called Arts. It also infects people with the progressive disease, Oripathy. Due to the 100 percent mortality rate, and the high infectivity at the time of death and unfriendliness towards the infected became widespread. This led to a mass quarantine and expulsion by governments worldwide. Subsequently, tension arose between the non-infected and the infected.

Players take on the role of the  amnesiac Doctor. They command a team of operators on Rhodes Island, a medical, self-defence and pharmaceutical organisation. As the disease spreads, the team searches for a cure while defending themselves against threats such as the Reunion Movement.


Arknights currently features over 200 operators that players can obtain. It can thus be very confusing to know which character is worth having. Luckily, the characters have been divided into eight different classes, and each character has been ranked. The S-tier features the best and rarest characters to have, while the C-tier features the most common and below average characters.

It is also important to note that each class features multiple sub-classes. Each sub-class has its own unique abilities and skills. The following table indicates the name of each class, as well as the general characteristics.
