The MEC-4 Alastor is the world first miniature fully functional MEC.
There isn't much information regarding Alastor development, its known to be a design that Al and Jeff Bowen made themselves for a highly compact ground combat unit that could be deployed and used as anti personal and anti materiel and thus with the miniturization of the certain parts, Alastor was created. Using a MMI it responds to operators thoughts and emotions almost instantaneously making it highly mobile, it’s invulnerable to most small caliber firearms, equipped with cannons attached to its wrists, all in all its an infantryman nightmare. Its highly successful against soft targets, given its combination of high mobility, firepower and defensive capabilities it can annihilate infantry units with ease. Its vulnerabilities are in the joints and against larger caliber munitions, 0.50 BMG and higher.
