The second tier of Hydra units designed were the Hydra Mechs. They were autonomous soldiers and needed to be one level above a soldier but not as advanced as a higher tiered Mech that was to be determined in the future. They needed to be bulky and less refined.
The Riot Sleeper had giant fists and hydraulic pistons to smash their enemies with extreme force.
The Ranged Sleepers had shoulder mounted rocket launchers and a canon arm.
