By solving the two main problems with the beam weapons - the size of the power elements and overheating of the build-up cavity - we were able to create a combat raygun. Several forms of the weapon were developed to suit various purposes.
Small size limits the potential firepower of this weapon, making it inferior to a rifle. However, it still surpasses all of its bullet-discharging analogues.
A beam emitter fits perfectly into the form factor of a standard rifle. The beam can cut through a plate of metal, not to mention flesh. This weapon excels at medium range.
To minimize diffusion while firing over long distances, a complex collimation optical system was invented. The downside is that the rifle is very ineffective at close range.
High rate of fire and a huge energy reserve make the beam gun a perfect close-range weapon.
