The game is based on the moon, a meteor impact damages the moonbase and you have been called in to clear away the debris that has fallen. Travelling from level to level (10 in total) you are given an infinite collection of bombs to blast away rubble. However, the nuclear reactors around the base have been left online and if hit one too many times they wipe out everything on the level. You also have to avoid malfunctioning security robots which wander around the levels, killing you on contact.By destroying the fallen rocks, extra blast fuel can be uncovered and picked up which gives your bombs a greater range and kill threat. Extra bombs are available and these enable you to drop more than one bomb at any time.Mystery boxes left under the debris can have various effects, including setting you to auto-bomb-drop, freezing the droids, increasing your bomb range and giving an extra bomb. There is a two-player mode over Wifi in which you can go head-to-head, trying to trap each other with their bombs.
