The ZTZ88B (Chinese: ZTZ88B式主战坦克; industry code WZ122E) belongs to the WZ122 family of MBTs and is the first mass-produced variant of the ZTZ80/88 series. The WZ122 series originated from the Object 122, developed in the late 1960s to early 1970s as Chinese engineers sought new armoured vehicles for the PLAGF. Although the initial program was cancelled due to a change in direction, one prototype, the WZ1225, underwent PLAGF evaluation and was subsequently designated as the PLAGF's new second-generation MBT, retaining its industry code WZ122.

Initially manufactured as the ZTZ80-I for evaluation, the need for new MBTs, with the third-generation MBT (Project 784; later renamed WZ123 and ZTZ99) still under development, led to a fusion of the ZTZ85 hull and the ZTZ80-I turret. This amalgamation entered service as the ZTZ88B and was first showcased during the 50th National Day Parade.

Introduced in Update "La Royale", the design shares many similarities with its successor, the ZTZ88A, featuring a longer 105 mm cannon. Players familiar with the relatively slow turret traverse speed and top speed of the previous ZTZ59/69 series will appreciate the ZTZ88B's improved gun laying system. Additionally, it boasts experimental applique armour for enhanced protection against both kinetic and chemical shells. Coupled with a new 730 hp engine for improved mobility in all directions, the ZTZ88B serves as an excellent training vehicle for later PLAGF MBTs.
