Hydra — About this game
Hydra hires its armed boat to deliver secret cargo through defended waterways. Fuel and boost crystals sustain the route, while the boost can launch the craft into the air. The gun handles ordinary attacks, with selected special weapons providing other responses to enemy patrols. Cash from deliveries and bonus sections pays for weapons and additional fuel. Keeping the cargo and reserves intact helps reach the next delivery rather than merely winning an uninterrupted race.
