Bricks from Timesplitters. But seriously, Timesplitters and Perfect Dark has some crazy fun weapons. Playing a flare gun only in Timesplitters 3 is absolute madness!

This look really cool. What game is it from?

Remote mines in GoldenEye have always been my favorite. There's no feeling like setting one, watching someone walk up to it, hitting the button, and then... Kablooey!

Yes, so much fun. I was actually considering the Golden Gun for my opening example but I couldn't find a good picture. I had so much fun on Facility with both.

The golden gun is another good one.  One shot.  One kill. 

But if you miss, you have to reload...

Definitely my favorite weapon in the game. I used to duel my friends in the bathroom on Facility (the spawn was under the urinal if memory serves). Shame the movie sucked.

Hehe.  You didn't like GoldenEye?  I thought that it was pretty good if you got rid of Pierce Brosnan...  Actually the movie GoldenEye was more faithful to Ian Fleming's novel Moonraker than that movie with Roger Moore in space was.

In order to get this thread back on track I will list another weapon.

The BFG from Doom.

Whoops, I was actually referring to The Man With the Golden Gun. I thought Goldeneye was a pretty good movie, but Casino Royale was such a better introduction for a new Bond that it's fallen a bit in my eyes.

Oh, and yes, the BFG was awesome too.

The Auger. Resistance games.

Its from Singularity.  Its really more of a multi purpose tool than a traditional "weapon", but since i can turn people to ash at the flick of a wrist, i think it fits here.  The game is really quite amazing, would highly recommend it.
