Definite approval for the aforementioned Wabbajack and Sheepinator. I'd say the hidden blade from AC, with the Gravity Gun from HL2 and Lava Whip from R&C2 close behind.

theres only one weapon that stands above the rest for me. the mighty REDEEMER, your personel tactical nuclear device lol.

I love the harpoon gun from Crackdown. Give them a good kick and shoot. You can peg them anywhere! And then you can shoot the body in a different place so the body ragdolls differently all the way down a wall. Nifty.

And who can forget the Hadoken? That's a fraking fireball doom weapon!

Fists
Feet
Knees
Elbows

The funnest and most personal weapons you can use. Never needs reloading and you always have them on you.

The coolest weapon ever was and is the machine gun from Gears of War. The one with the Chainsaw Bayonet. Chainsaw+Machine Gun=Awesome Violent Fun

I'm a fan of any sniper rifle, the landshark gun from Armed & Dangerous, the fuel air bomb from Mercenaries, and the goop gun from UT but...

My favorite weapon to use, hands down, is the sticky grenade in Halo 2.

I've been having fun with the syringe gun in TF2 lately. Arcing fire over obstacles or ledges to take out guys is amusing.

Although I still think "The World's Most Interesting Bomb" from MDK takes the win.

Oh, how could I forget to mention the nuke in Shadow Warrior.
Extremely fun in a death match.
You run around looking for your prey when you suddenly hear "3... 2.... 1... all systems ready."
Run, hide and pray!

mhm..

Red Faction flamethrower, oh man, shooting aint working.. "throws magazine as a fire grenade"
That red faction shoot through walls infrared sniper thing that raped the entire map.
Maulers from Halo 3, hands down favorite close combat weapons.
Strange Sword of Haste in Diablo one (i had a perfect one "muhahaha")
Any Grenade launcher/cannon in the Armored Core series, explosions deluxe!

now for super weapons..

Redeemer, BFG 9000, Ion/airstrike Painter, NUKES NUKES NUKES any nuke = good

And offcourse, the mega powerfist in Fallout 2 super sledge hammer too... and gauss rifle :D

The Sister Ray from FF7.

Vs Diamond Weapon
Vs Saphire Weapon

And the Dispersion Gun from TimeSplitters 3 (futuristic shotgun using energy instead of buckshot)

The Flak Cannon from the UT series. How can one not like the most vicious shotgun/grenade launcher combo ever created by mans desire to inflict pain on the the universe?.

MrCIA - Certified Flak Monkey.

Its funny that noone mentions the good old Mega Buster from Classic Megaman. After you beat your opponent with it, you get their power. Its funny how the simple things are usually the most effective.

the only part of megaman i like is the music ~~

I'd go for an axe, or a shotgun.

Or a shotgun the fires axes.

I like any type of olden rifle that makes a nice crack, a one-hit-kill, and has the lovely bolt-action sound. Like the ones in RE4, or WW2 games like Day of Defeat.

R.Y.N.O.

Rip Ya a New One.

The mini chainsaw AKA clownsaw from Dead Rising.

Beowulf gauntlets and boots from Devil May Cry 3 ^_^
Nothing beats gettings up close

For me, it has to be either the Smartgun from the AvP series, or the Lancer from Gears of War. I mean, the Smartgun is just so ludicrously awesome in its concept. And on top of that it makes that perfect sound, that singular gunshot noise that all games should aspire to have. The noise it makes just grinding through hordes of drones was just so...satisfying.

On the other hand you have the Lancer. The Lancer's not only a great ranged weapon, but theres just something so deliciously novel about charging out of cover in a screaming bayonet rush of Chainsaws. I mean for fuck's sake. Chainsaw bayonets. And then theres the blood spatter from that thing, holy shit.

Super Mario 64 Lightning Bolt
Cel Damage - Axe
Dead Rising- Shopping Cart
Final Fantasy (all of them) - Gunblade
Legend of Zelda's - The Cane of Byrna

The Death Star II in Empire at War: Forces of Corruption. Yeah, it's really cheap, but oh so satisfying.

The Air-Tazer in the original Syphon Filter. Anyone who's ever played knows that making low-poly terrorists burst into flames is always fun.

And Gears of War's chainsaw needed a mention.

The Ratchet and Clank series has always kept me entertained with a weapon that turns even the biggest adversary into a farmyard animal. One example is the Quack-O-Ray from the third game. While at first turning your opponent into a duckie, it upgrades to make the ducks lay explosive eggs, then making the ducks themselves explode, then making the ducks home-in, then making the first enemy you turn the ray on into a demon duck that follows you and attacks your enemies for you.

Oh jesus, the Air Tazer. I almost forgot about that beauty.

while not technically a weapon, more of a special move. i would have to say that babalities from MK:Trilogy take the cake. Turning your opponent into a baby to defeat them? awesome.

BZZZZZZZZZZZZZZZSSSSHHHROOOOOWWWWNNNNNNNNNNN

Given three choices I'd say:

1. The Shotgun from Halo:CE

2. The OICW from Far Cry

3. The wonderful Hunting Rifle from Stalker (not the Sawn-Off, I can't remeber the name.)

Each and every one is what they call "a twenty-four carat deathstick."

Lord_Sammael - Winner! Lightsabre clearly the most fun weapon to use in any game.

Modern/real weapon M4... Still not quite over my CS addiction.

Bladed weapons.... Well the old Gladius is a very cool sword.

Favourite BIG weapon - Tactical Nuke from World in Conflict

Favourite 'crazy' weapon too many to list.

The Serious Sam cannon.

It fires giant balls of rolling metal death that will explode on contact with any enemies that are too big for it to just crush instantly (Which makes it the SS equivalent of the Instagib rifle in UT2004 when it comes to PvP).

TheNecroswanson:
BFG 9000. Lord knows how it would function in reality, but it's still really cool. Loves it to death!

Yeah, any BFG. Even Quake III's.

Just because it's the BFG.

The chainsaw as well.

I spent hours on Star Wars Jedi Knight Killing people with the forces like Grip and Lightning, i used to love picking up the troopers and hurling them across the room or throwing them of cliff. This was before HL2's Gravity gun :) that was so awesome, i don't think i used another gun after i got that.

Let's see here: (Note: they're not in order, I just love them all)

a) Hidden Blade, Assassin's Creed: Put your hand on an enemy and "tsunk" he's deaaad.

b) 50. Caliber Sniping Rifle, Way too many games: You shoot on the head, you shoot on the leg, you shoot at a tank, you shoot at whatever you want, it dies.

c) Gravity Gun, HL: The enemmies are Half-Dead when you get this thing on your hands.

d) C4, BattleField 2: Throw 'em on a car, then ALLAAAAAAAAAAHH!!!!.......BUM!

e) Katana (Samurai Sword), Many games: The glorious, beautiful blade, hack,slash,stab!

I could get this list on and on, but I'll stop here.

~~Dante's fire gauntlets from the original Devil May Cry. Hand to hand has never felt more powerful to me in any game. Power 'em up, and you can literally explode your enemies with a single punch.

~~And there are few things in life as satisfying as a well-timed melee to the face in Halo 3.

*So* many to choose from! In no particular order:

- Grapple Gun (Quake CTF). Completely changed the geography of the maps. Worked quick and smooth and made for very interresting play.

- Trip Mines (Duke Nukem, multiplayer). Endless fun booby-trapping the powerup/health pickup points.

- The greatsword (Dungeons And Dragons Online). The first time you swing that into a pack of enemies after having dabbled with daggers and longswords is a big bunch of "Ooooh!"

- Gravity Gun (Half-Life 2). Comments superfluous.

- Oil Slick (Spy Hunter). And there he goooooeeeessss! *CRASH*

- P90 (Counter Strike). Nothing says "Get out of my friggin' way!" quite like putting a bullpup SMG in belly-height and letting a full 50-bullet clip rip right through a pack of enemies.

- JDAM-154 (Jane's F/A-18 Simulator). "Smart pigs". GPS-guided winged bombs. Come dashing in at tree-top level, pull up hard until you are in optimal toss angle, release and dart to the side. Bomb does a pretty parable and finishes the job for ya without you having to expose yourself.

- Fireball (Baldur's Gate Series). The ultimate room-cleanout. Caution: do not use in close quarter battle.

- .45 Pistol (Delta Force). Most fun moment ever: came up behind someone sniping with a Light 50 (Barret M82), completely oblivious to the fact I was standing at his feet. I pulled out the .45, triggered an audio emote saying "Hey, behind you!". Just after the thought "Oh shite, I'm getting screwed" flew through his mind, I let three bullets do the same.. then walked away with the most smug grin ever seen.

- Lynx (Buggy equipped with rocket launcher in UT2004). Perfectly balanced and easy to manouver despite having to control both vehicle and where you are looking. Could easilly have been cocked up and made an user-unfriendly nightmare... but instead they are just about right.

- Satchel charges (Operation Flashpoint). Totally unapprechiated... until I discovered that they can be set on a timer. Problem: covert-ops trying to take out three targets that are spread out + limited range on the radio detonator. If I take out one or two, the remaining one(s) get alerted and all hell breaks loose. Solution: I snuck in under each of the targets and set the timers so that they would all be blown up simultaneously. Snuck out and put myself on a hillside near my extraction point almost a kilometer away and quietly waited for the fireworks. Timers reached zero on the same second and BOOM! *sigh* It was beautiful.

- Spy (Civilization II). That klaxon reving up... followed by the marvelous, earth-shattering KABOOM... a *beautiful* mushroom cloud animation. Doesn't get much better.

Grenades from Quake 2 (twist and throw!) and both the Topsy-Turvy bomb and Shark-Gun from Armed and Dangerous.

GrowlersAtSea:
The Chestburster from Turok: Rage Wars.

The game itself was pretty bad. An arena style multiplayer game with a lot of generic aspects, and the game had an unfinished feel.

But the Chestburster was very cool. It was kind of slow, but if you could hit another player with it, they had around 12 seconds before they fell over and an serpentine creature rips out of their chest. Isn't a very original idea, alien ripping out of someone's chest, but it was just a very cool gun to have. The Turok series featured some very fun weapons overall, it's a shame the series kind of went down the drain by the third installment.

Also, the Snarks from Half-Life. Not really a gun, but it was just so fun to let three go in a room with some Marines then charge in once they start firing trying to stay them off. Some very nice animations too when you just had the Snark out and idled.

Yes, LOVE Turok Rage Wars, and even though the Chest Burster was one-hit kill, it was pretty much a hit-or miss weapon. The recharge was pretty slow and if you miss, you probably weren't getting another chance. It was a challenging weapon to master, but it was definitely awesome.

Also, the Inflator from Turok: Rage Wars is probably the most hilarious weapon ever created. I love it.
