Everyone Hit the Traitors is a Chinese web game that lets the player attack and subdue Hong Kong protesters, including caricatures of prominent political activists (via Abacus News).
The game takes place on a street in Hong Kong, with shambling protesters wearing hard hats and masks.
A counter on the right tells the player how many Hong Kong activists they have arrested.
This is not the first game to interact with the pro-democracy protests in Hong Kong.
