The Light Beam is a tier 2 beam added in v2 a1.1.0 that can be seen as a side-grade to the Nova Beam. It fires high energy beams of light that do extra damage to darkling enemies, and less to non-darkling enemies. As no darkling enemies are currently in the mod, this beam is currently less favorable then the Nova Beam, and should only be unlocked once the player has acquired the Annihilator Beam upgrade, as it is required to upgrade the beam into the Annihilator Beam .
