Ballistic weapons are direct-fire / direct line-of-sight weapons that fire unguided high speed projectiles, damaging a target through their initial impact / post-impact concussion. Ballistic ammunication is hard-cast (ie. a physical object such as a slug, bullet or other type of projective with mass and weight). The rounds are propelled from the weapon by either chemical or electro-magnetic means.
Beam weapons are direct-fire / direct line-of-sight weapons. They are extremely accurate because their time-of-flight (TDF) is measured in nano-seconds. In other words, the beam travels from the weapon to the target in the blink of an eye. Like plasma / energy weapons, beam weapons draw power from the vehicle's energy reserve. If too much energy is consumed too quickly, other systems may be temporarily shut down.
Plasma / Energy Weapons
Plasma / energy weapons are direct-fire / direct line-of-sight weapons that fire a charged globe (or pulse) of plasmic energy. Instead of using ammunition like slugs, bolts or bullets, plasma / energy weapons draw energy from your energy reserve. This means less weight is placed on your chassis and more space is made available for storing other things. The main benefit to using these weapons, however, is that they are powerful and have excellent range.
Missile weapons are significantly different than other weapons in your inventory. They are the only weapons (with the exception of some special weapons and mines) that do not require the shooter to have a direct line-of-sight to the target. They are also the only weapons (other than the smart gun and plasma cannon) with the ability to "lock on" and track a target after they've been launched.
Primarily defensive in nature, mines provide the means to deny the energy the use of an area or channel an enemy's movement into a predictable route. They can also be used to delay an enemy's advance when friendly forces are retreating. Mines are proximity fused, or in the case of the cybrid arachnitron, set to actively seek out a target. These cost effective weapons are a welcome addition to any squad inventory. In emergencies, mines can also be "thrown" like grenades.
This final catch-all category includes exotic weapons belonging to both Human and Cybrid forces.
