Tachyon and Neutron weapons are quite similar. All Neutron cannons have a fire rate of 4.0 SPS (Except the Farmers Alliance which is at 3.03 SPS). Most Tachyon guns also deliver 4.0 SPS, however, there are Tachyon guns that fires faster at 5.88 SPS (Rheinland) and slower at 3.03 SPS (Outcast、LWB and Bundschuh). Tachyon and Neutron weapons are most effective against Molecular shields, and weakest against Positron shields.
