The Aquanauts Quad Blaster is a high-powered and fast underwater vehicle. It lacks mobility, but is made up for by it's high speeds and powerful lasers. It is often used to defend Aquanauts bases against the Aquasharks's invasions.
Design Notes: I was fooling around with those octagonal cockpit parts and I just wanted to make Aquanauts. I also used those beam pieces which WON'T STAY ATTACHED! (very bad "sticking" power...), and it worked decently.
