Pentaplane is a fun and quite unique 3-dimensional chess variant with many new and interesting pieces, like Missile-rooks, kamakazee queens and bombs.

The object is to capture, shoot, or explode the emeny king.

Missile-firing pieces shoot in the direction they move. You may shoot to explode a bomb - but not your own.
When Bombs explode, they annihilate a 3x3x3 section. All pieces disappear, but other bombs are not ignited.
