Tired of a single turret detonation causing a chain reaction that kills your entire base? Sure you put your turrets far enough? Wondering what madman stuffed your turrets with explosives more lethal than blasting charges? Worry no more. This mod decreases turret explosive range by 66%, down to 1.3 tiles.

Yes, it's a very simple mod. You could just go in and make the edit yourself, probably.
