Changing in and out of proton mode turns the laser off before it moves the pistons. This isn't a bug, it keeps the laser from breaking.
8 different photon beams. Red, yellow, green, cyan, blue, magenta, and white. The photon beams are all 9725.85 C. It can shoot Proton beams too, those are about 9700 C. It has a neutron mode, which is 9725.85 C if the proton mode is off.
