Madness Hydraulic

Madness Hydraulic, a arena-based shooting game that is an integral part of the Madness series of games. The game features as many insanity weapons as the other games in the series, however, it also comes with an exclusive feature: arenas that are hydraulic. You must get through waves of enemies by killing every enemy that appears by any methods necessary, such as with their own weapons and all the while engaging in an open arena that occasionally shifts due to hydraulic mechanics.
