The Tau Cannon (2/12)

This unbelievably powerful energy weapon packs a surprising punch, with a recoil big enough to send you skyward. The Tau Cannon has two different firing modes: one that shoots yellow beams at a decent rate, and another that charges and unleashes one powerful shot. Better yet, the Tau Cannon doesn’t need to be reloaded, and will keep firing until you run out of ammo.

The Tau Cannon is one of our favorite Half-Life weapons because of its neat design, unique firing capabilities, and its overall power. With the charged shot, you can cut through enemies and walls alike, taking out multiple foes at once. You could also clean house with it in multiplayer deathmatch, thanks to its incredibly high damage output.
