Most fun weapons in FPS multiplayer games?

[Losonti Tokash]

My favorites are Halo's sword, plasma grenades, and shotguns. I also loved the railgun from Perfect Dark, but Halo's shotguns have a special place, mostly because of the sheer carnage I can unleash when I grab one. Even more so because I normally despise shotguns in other shooters.

For those that remeber it...the cow launcher 2000 from South Park........ it launches a cow at the target. Cow lands on the target anus first...So you get to see your target running around with his head up a cows anus suffocating to death.

Let's see,

The original UT, GOTY edition:

The teleporter beacon.

Oh man, loads of fun, especially if you found a few on another team packed together...fire and teleport, fire and teleport, paint the walls.

The Gravity Vortex.

This one, on an open map, made for the most hilarious suicide-rushes, as I run in, activate the vortex, and sacrifice myself to it, listening happily to the many cries of 'Oh sh..."

The Relic of Vengeance.

Another of my favourite 'Oh shit' weapons. Don't even fire, simply rush a group of them and let them slaughter you. The best part is they have that half second of realization before the big skull floating over my corpse merrily explodes.

Half Life:

Snarks.

Great Cthulhu those things are so much fun. Watch a charge turn into a panicked retreat as the aggressors are repulsed by a half dozen, kitten-sized packets of explosive energy.

The Hive Hand.

Especially on corridor type maps, just keep one bend ahead of them and keep firing as you retreat. Half the time, they don't even notice their health has gotten so damn low until it's too late.

Just for the comic value anything from the South Park game, theres just something about death by yellow snow or one of the other great weapons thats so much fun.
