This is "Maelstrom's" choice vehicle, the Helisub. It is a helicopter that can travel under water so now "Maelstrom" can go airborne. It has a very small weapons system to the eye, but this has a laser cannon, two anchor clamps, and when "Maelstrom" attaches himself to a rock formation, he can switch his Helisub into Helicopter mode and cause a maelstrom! It is camouflaged to hide in the deep waters to make great sneak attacks.
"Maelstrom" is the Water member of the terrorist team Doom. For more information, click here.
Behind the Scenes Trivia: I felt like a helicopter and a submarine would make an interesting ship, and it works very nicely. The helisub has top and side propellars, and three rear propellars so depending on what terrain the Helisub is in, it has a practical way of movement, unlike Magma Skis or what have you.
