The Pugnatroid was destroyed... A new mecha was required. From the scrapped remains Epsilom was built. A Superior manipulation arm, more axis of aim for the missile and a few armour modifications were added. Primarily Designed for urban warfare the hand can be used to make ad hoc weapons as and when they are needed.
I essentialy did just as described to the first mecha i made like this. The hand can hold a variety of objects.
