Original: They range from Duke's "Mighty Foot", a basic melee attack, to a pistol, a Chain gun (similar in design to the Nordenfelt gun), pipe bombs, freeze- and shrink-rays, laser trip mines and even a very powerful rapid fire rocket launcher called the "Devastator".
Simplified: They range from Duke's foot for kicking, a pistol, a "Chain gun" (similar in design to the Nordenfelt gun), pipe bombs, freeze- and shrink-rays, and laser-trip-mines.
