Resurgence is an upcoming Skaarj campaign/mod for Unreal v227. It includes new maps, weapons, enemies, and features.
The stinger's primary fire charges enemies with tarydium, but isn't the most useful against flying or agile enemies. The new secondary fire is normally inaccurate and weak, but it homes in on and deals more damage to enemies who are charged with tarydium.
Excellent, unique, interesting!
