Greatest Video Game Weapon ever?

[MattyDienhoff]

With a strong basis in reality: The M21 in the first Operation Flashpoint.

A 7.62 battle rifle with a 20 round mag and adjustable scope that can and usually does kill with one shot to the torso? Hell yes. Since the game has proper ballistics you have to lead moving targets and adjust for drop over long distances, and there's nothing quite as satisfying as carefully lining up a shot on a moving target, firing, and watching the target drop like a sack of potatoes.

Fictional: Easily Half-Life's Gravity Gun (or "Zero Point Energy Field Manipulator"). It's just a multi-purpose ass-kicking tool that's a riot of fun to use.
