Gauss: A fairly common and practical alternative to lasers, Gauss weapons are typically more powerful than lasers but much heavier. The weapons use a magnetic coil surrounding a barrel to fire a solid dense-metal projectile at high speeds. The process itself is very quiet however the sound of the weapons energy matrix for the brief period of firing is quite noisy and the sound of the projectile breaking the sound barrier often makes any attempts at silence moot. These weapons are effective even against heavily armored targets as while the solid rounds penetrate most materials, even when stopped they transmit much of their kinetic energy into the target. Horror stories of soldiers wearing armor “just heavy enough” to stop the round but still end up the consistency of soup inside.
Graviton: Efficient safe and easily maintained, harnessing the power of artificial gravity, graviton technology is found in every starship. Graviton emitters are found in, life support units, gravity boots, jetpacks, subliminal propulsion, protective shields, forcefields, weapons and tractor beams.
Hardlight: Discovered on Earth in 2014 hard light technology works by coupling photons together, creating physical particles with functional mass and density, these newly formed particles are linked together in order to create hard light structures. The most practical use of hardlight technology is containment force fields and protective shielding. Some of the more unusual applications of hardlight are tractor beams, tools, and bladed weapons.
Laser: Small light, rugged durable dependable and with unlimited ammunition lasers are found in all shapes sizes and colors. Despite having less power than a rail or gauss weapon, lasers are easily made to be omnidirectional and have absolutely no ammunition requirements. Due to their ruggedness cost and weight, lasers are one of the most common side arms in the near-Earth sector of space.
Plasma: Using high energy fusion reactions, plasma technology tends to be powerful and light but use large amounts of energy. Plasma weapons work by encapsulating plasma is a magnetic field as it forcefully ejects from the barrel of the weapon. Plasma drives, work by energizing portions of the plasma and allowing it to escape the containment field in a directed manner.
Rail: Much less finicky than their gauss cousins, rail weapons instead use a pair of magnetized rails to accelerate a solid slug to an enormous velocity. Rail guns require more maintenance than gauss weapons and are more prone to wear and tear as the rails must be in contact with the slug at all points of the firing process. The rails, though not delicate per say, tend to get tore up and fall out of alignment over extended use and require maintenance every 100 or so shots. That being said the technology scales in size considerably better than gauss weaponry, with heavy rail sniper rifles weighing only a few lbs more than a standard gauss rifle. Rail weapons also exist in a man-portable fashion, though are often fired from a tripod or other mount rather than shoulder mounted. To avoid significantly damaging the gun only one piece of ammunition can be in contact with the rail at any time, as a result most rail weapons contain only a single shot or are bolt action; though select “slow” ammunition feeds exist. This puts a natural limit on how fast the weapon can fire.
