Battlesuits are some of the most advanced pieces of precursor military technology that have been discovered as of now. The ancient machine features an organic closed-circuit, an atmospheric filter, extra-human sensory perception and sensor fusion, nigh-indestructible plasteel alloy armour, autonomous power in the form a miniaturised fusion reactor, and two integrated plasma weapons; one mounted above the shoulder launches bolts of unstable, low-speed plasma which can melt through armour and burn enemies in a large radius around its area of impact; the other, mounted below the left arm, is an fast-firing automatic weapon which launches small bolts of superstable plasma over decently long distances.
However, because precursor anatomy was not the same as human anatomy, it is somewhat uncomfortable to wear. The user interface is also in undeciferable runes.
Some say this piece of equipment is nothing but a myth...
