Thief
大盗
Thief is an action arcade game released in 1981 by Pacific Novelty. The player controls a thief navigating a maze-like environment while collecting items and evading pursuing enemies. Similar in concept to maze-chase games popular at the time, Thief tasks the player with grabbing valuables scattered across the playfield while avoiding guards or enemies that hunt the thief down. The game uses a joystick for movement and increases in difficulty as stages progress, with enemies becoming faster and more aggressive. Completing a board advances the player to the next stage, maintaining the same core loop. Pacific Novelty produced a relatively small number of arcade titles, making this one of the less commonly encountered cabinets from that era.
