#5 Leech Gun- Prey - [ Xbox 360 ]
Melding alien technology with human weaponry yielded some strange but sinister weaponry in Prey. The best of the bunch was the Leech Gun, which could make use of various types of ammunition located at reloading stations. You start off with Plasma and Ice ammo, which give you your standard flamethrower and freezegun capabilities. Later on, you can make use of Lightning and Sun ammo which allow you to shoot powerful beams (Lightning has short rifle-like shots, Sun is a steady "Hammer of Dawn" style beam) that can obliterate your enemy with ease. With a weapon that versatile, you might just forget about the rest of Prey's impressive cadre. Please don't.
