Resurgence is an upcoming Skaarj campaign/mod for Unreal v227. It includes new maps, weapons, enemies, and features.
This energy-based gun is employed in high-priority mines where slave escapes and riots have become problematic. Primary fire charges up a weak beam that pushes enemies backwards; secondary fire does the same, but the beam pulls enemies towards the user. It does low damage, requires accuracy, and isn't suitable for heavier foes, but the stunner is good for pushing enemies into hazards or getting them within reach of your razik.
