Nali Weapons 3 is a new weapon pack for Unreal Tournament, containing 17 new weapons, new pickups, ultra gore, nukes and more.
It casts a lightning storm for about 30 seconds (configurable). The lightnings may or may not hit the opponents directly, but if they land nearby they may still kill.
I have to say that the screenshots do not reveal that much of what is really going on in-game (effects-wise, as the electrical activity is a lot more intense than what's portrayed here and aren't meant to be seen as still images). Soon I will make a preview video on this and the other oversurrections.
