Main article: Purple Skull
The Developer's No. 4 Craft blueprint is obtained through placing the Purple Skull in its proper location.
It has the appearance of a Short Circuit Mod and has a 100% chance (before skill bonuses) to cause zombies' heads to explode. Use sparingly on other entities (repair cost from 0%: $11,672). Only works against Walkers, Infected, Thug(s) and Infected Ryder White.
- This weapon is dangerous when Logan uses it with the Economical Throw Skill which will do damage to nearby enemies
