Sphere shooting squares

 are hazards in Fault Line. They are similar to Lasers. They consist of 2 blocks and an actual sphere. The 2 blocks are usually positioned in a wall, usually in a vertical or horizontal line. They must always be facing each other in order to exchange spheres. There main and only attack is for one block to fire bright spheres at another block, and for the receiving block to catch the spheres.

The sphere will instantly kill the Purple Robot on contact, and cannot be passed without being folded in with a Fault Line. The actual block is made of metal, and has a hole on the top. The spheres are shot out of one block, and received in the other.
