500 years in the future...
The First Corporate Dynasty of the second millennium is ruled by the tyrannical SovKhan (short for Sovereign Khan) from the vast seven mile high Megacity S1-9. Using cybernetic embryos and a mysterious substance known as Dark Matter, SovKhan has begun growing an army of giant living robots known as Slaves. In an attempt to rule the world, SovKhan plans to use these robots to enslave all of humanity.
Underneath Megacity S1-9 is a system of sewage tunnels called The Suck. A rebellious group of spiritual warriors, or Guardians, have made the sewers their base of operations. Having successfully stolen a Slave unit, the Guardians are not about to let SovKhan's reign go unchallenged. You take on the role of Chan, the one Guardian chosen to fuse your mind and body with that of the stolen Slave unit. As Chan you must command Slave Zero and save humanity.
While controlling Slave Zero you will navigate Megacity S1-9 and The Suck, destroying all that SovKhan has created. Your Slave is equipped with a ballistic weapon, a power weapon, and a missile launcher, which are consistently upgraded as you progress through the 13 mission-based levels. In addition to these weapons, you have the ability to pick up and throw certain objects, such as cars and steel girders.
The levels are set up so that you must fight your way through conventional military forces, sentinel-class assault units, and other Slaves in order to reach your objectives, which range from destroying power generators to stopping the city's train ways to stealing cybernetic embryos. As you progress through the levels, power-ups, such as health, ammunition, and upgrades are made available. Each level ends with a boss encounter.
In addition to the third-person 3D story mode, Slave Zero has a two to four player deathmatch mode, which is played via split screens. While playing the deathmatch mode, the camera shifts from the normal third-person perspective to a first-person perspective. There are a total of ten arenas specifically designed for the deathmatch mode.
Slave Zero requires two blocks of memory in order to save a game on a VMU. Also, it is compatible with the Jump Pack. ~ Damien Thorpe, All Game Guide
