Version 1.1 From : Half-Life 1 Concept : Most Accurate SlashAndBurn's Comment : This is the best looking version for accuracy, but also the most difficult to produce. If you are up to a challenge make this one.
	Version 2.0 From : Half-Life 2 Concept : Accurate SlashAndBurn's Comment : This version is less difficult then version 1.1. It's just a matter of taste, make this one if you like how it looks.
	Version 3.0 From : Half-Life 1 Concept : Simple SlashAndBurn's Comment : Think of this as a beginner’s headcrab. Each half is only made up of 8 parts. If you want to make one by hand and not do to much sewing, make this one.
