Sury Ani 7 has been a source of mined resources for many a year, but now that it is contaminated, the only way to harvest its bounty is to do so remotely. Worse still, the security system of defence droids is active, and primed to damage anything which attempts to penetrate the surface. As such, you are in control of a Dedicated Disposal Droid in, which must eventually shut down the security system and clear the area of radioactive material. This is done by throwing it down the disposal chute on each of the 8 levels, but you only have limited time before they explode. Fuel is limited and must be found within the complex, with the retro-thrust move using it up particularly quickly. To reach the next level you must find the appropriate pass.
