Official Mission Pack for Activision’s BattleZone. It is a Battlezone add-on
from Team Evolve (the folks behind the respectable Zaero for Quake II)
consisting of 23 missions set on the moons of Jupiter.

A platoon has disappeared while playing nursemaid to bio-metal-collectign
scavengers on Ganymede, and Russian involvement is suspected. In fact, the
enemy is China – a China using cloaked vehicles that suddenly turn up, guns
ablaze, in the middle of your base. When playing the 15 missions as the US’s
Black Dogs, you can also play as the Chinese. This lends the game an
increasing sense of uncertainty.
