The strange technologies of the Heleus Cluster offer many outlaw and exile groups opportunity rather than scientific mystery. With access to black-market salvage, Remnant technology, and stolen gear from the Andromeda Initiative, some have crafted non-standard but highly effective battle mech suits nicknamed "Hydras."
Most Hydra units are armed with a chain gun and a devastating laser-guided RPG volley, pinning down enemies before bombarding them with heavy fire. Unapproved jumpjet designs and a mass-lowering element zero core assist in ground clearance or leaping at a target. The sheer weight and impact of the Hydra unit can crush enemies or force them to fall back. APEX officially classifies a Hydra unit as a Priority Zero threat, though unofficial communications often use the acronym "BFM."
