Your homeworld is under attack by alien forces, and the only way stop the
aliens from bombing your world to ruins is to neutralize all bombs before the
ground it hit by them.

For this purpose, you control a multi-layered collector/reflector. Simply move
your vehicle below a bomb, and it will catch them (standard bombs), re-bounce
them (advanced bombs), or you loose a layer of your vehicle (spiked bombs).

So, your job is to “collect” all green and yellow bombs (the standard bombs)
and re-bounce the blue bomb so that it will destroy the enemy ship. If one of
those three bombs hit the ground, you loose one layer of your three-layered
vehicle (basically one out of three lives). However, when you see a red spiked
bomb, you have to avoid it. When this bomb hits the ground, nothing happens,
but when you collect it, you loose a life.

Besides the bombs, there are other things in the level too, like a bomb
splitter (making two bombs out of one), a bomb redirector (changes the course
of the bombs), and a bomb accelerator.

The game itself offers two game modes, Conquest Mode , that’s basically a
campaign, where you play through 50 levels, and Survival Mode , where you
play without levels.

When you start a game, only one alien ship is your enemy, but later, you have
to battle multiple enemy ships at the same time. There are even games, where
the playfield is reversed (both upside-down and mirror are possible).
