This weapon shoots a bolt of accelerated particles at near light speed that transfer massive amounts of kinetic energy to the target, superheating and creating an explosion when striking. The bolter's beam is not diffused by the cloud that occurs when it strikes, and so it has greater penetration than the laser pulser. Likewise, the bolter is not affected by smoke, fog, or rain. The bolter's beam is invisible. Note that bolters are designed for either atmospheric or exoatmospheric (vacuum) operation, and will not function in the opposite environment (though bulkier dual models, combining both models, are also available). Bolters fire in semi-auto mode and are rifle-sized two-handed weapons.
