What's the most overpowered attack, weapon or ability in a game?

[Robert632]

Shotguns in ME1, I could kill a geth from 30 metres away while not even aiming at it, in one shot.

Y'know, I never found shotguns in any ME to be particularly OP. Even point-blank and getting every hit I could get out of it, I rarely ever got anything below a two-three hit kill.

It could just be Insanity's bullet sponge enemies nature though.

O.T: Poison ion FFX. It tends to deal massive amounts of damage( I think around 25% of max health).

In X-Com the Psi Amp. You can win any mission by having your Skyranger full psi amps users, find one alien mind control it then use the vision of a mind controlled alien to find other aliens and mind control them. End result is a chain of aliens watching each other so you can control them every turn. Also the game didn't let aliens pick up weapons from the ground so you can make them drop there weapons and "pacify" them.

The rocket launchers in RE5 are worth mentioning, especially when you get unlimited ammo. My friend and I went through the entire game using them and we finished in less than 2 hours. Seriously, that giant boss you kill with the space laser? That sucker died after 2 hits with the rocket launcher.

Final Fantasy 7 : Knights of the Round. Powerful my itself, but you can pair it with other materia to make it insane. I went with MB Absorb - a devastating attack that gives you back way more mana that you spent to cast it ...

I remember binding knights of the round to MP absorb and HP Absorb. it would give about 1024 mana and 10500 or so health. I didn't even know the game could display the regeneration of more than 9999 HP and 999 mana in a single ability but it could for that ability.

That is nothing. Knights of the round paired with Quadra Summon. Every other materia slot? Mime + Counter. Now every time you are attacked, you will respond with Knights of the Round 6 times.

THAT'S BROKEN.

That's also six minutes of your time. I never used Knights of the Round except on Sephiroth, simply because I didn't feel like wasting an entire minute watching the animation.

Skies of Arcadia: Prophecy.

Technically, I don't think they even tell you about it in the game unless you meet the conditions in battle (and you still might not know what it is). However, if you know to save up for it, it's rather easy to get late game, owns almost everything, and acts as a free turn. The requisites of "you have to have max SP" and "No status ailments" are ridiculously easy by then, so the drawback is negligible.

 

[Metalix Knightmare]

Experimental MIRV.

Why Nuke something once when you can Nuke it eight times.

I'd say the MIRV is balanced out by the fact it REALLY sucks down the rather limited and hard to stockpile ammo it uses.

No, you want overpowered? Try ANY of the RYNOs from Ratchet and Clank. Any one of those suckers makes life a breeze.

Blacksmithing and Enchanting in Skyrim. You either need to turn the difficulty up or take off the gear you made.

This. I noticed that Blacksmithing doesn't have diminishing returns for leveling (so that making a dagger will give the same skill-bonus-to-level at Blacksmithing 10 as on Blacksmithing 90), thus I leveled from 5 to 22 just after I left Riverwood. Only time I stopped blacksmithing was when I ran out fo money to buy supplies. One sidequest later, and I leveled another few levels by simply creating daggers. At lvl 22, I had a full set of Ebon-armor, Ebon-greatsword, and I hadn't killed my first dragon. I think I four-shotted it when I finally bothered to do the mainquest.
Then I leveld Enchanting, enchanted all my gear (now I had Deadric, self-crafted) with magic-resistance, went out, killed shit, and stopped playing. There was no challenge.

 

[bluegate]

Alchemist/Death knight or w/e combos in FFX-2. Two of them to mash that aoe and one to spam mega potions, NO SKILL NEEDED LOL BAI.

Also Yojimbo in FFX

As for FFX-2, how about Catnip & Yuna's TriggerHappy ?
I remember that being quite the gamebreaker.

FFXIII
Poison, although not many bosses were susceptible to it, if you found a boss that was, it was almost instant win.

MMX
Hadouken, although you would only be able to do this move if you had max health, it would one shot anything it hit, boss or mob.

MMX4
Black armor X's Novastrike, would deal massive damage on anything it hit, killing almost all mobs with one hit and most bosses in two or three. Also, if I remember correctly, you would be invincible during this move.

Shotguns in ME1, I could kill a geth from 30 metres away while not even aiming at it, in one shot.

True that, wondered why I chose Infiltrator on my first run through after starting again.

Seems like in the inFamous series the Ionic/Lightning Storm was crazy OP; in the first you just recharged and used it again and in the sequel the ionic cores were a dime a dozen so you could use it very frequently. Couple that with massive damage over a wide area and suddenly the game becomes easy.

And of course any of the grapple/throw moves from Soul Calibur IV lets you beat any story mode difficulty with insane ease.

While it's not really an attack per se, Vivian's hide ability in Paper Mario: The Thousand Year Door. What's more, the game encourages its use! The final boss fight practically begs you to use it when Big Baddie uses its ridic damaging attack.

 

[GonzoGamer]

Warhammer 40k - Exterminatus litteraly cracks and destroys planets
Virus Bombs turns every biological thing on a planet into slime

Do you ever get to use that in a game? That would pretty much end any match, in Dawn of War or on the table.

I would have to say the Borderlands Hellfire smg. After my siren got her grubby hands on one she would hardly use anything else.
"Get a Maliwan and set some people on fire."

 

[Gatx]

Shotguns in ME1, I could kill a geth from 30 metres away while not even aiming at it, in one shot.

Psh, try Biotics. Between myself and Liara, no enemy ever spent more than a few seconds not flopping around the room as a ragdoll.

 

[Idocreating]

Mass Effect's Cloak. Just the ability to pull attention off you to find a good hiding spot can be enough to turn any hopeless fight around, and in ME2/3 the cloak lasts a decent length of time and has very little cooldown before you can use it again.

 

[Angelblaze]

Holy Cross on a Paladin in Final Fantasy Tactics Advance. You get them to a high enough level and honestly....you wonder why the 'attack' command is still there.

Falcon Punch- In SSB and in life. I don't even think I need to explain this more. You know the meme.

Convenent Prophet's Beam in Halo Wars- I wrecked so much with this beams. its not even funny. The enemy can't even get to you fast enough 1/2 the time to stop you from destroying 1/2 their army before they take a step. Especially if you bring more units then just him....

Evie's Thread snap attack in Vindictus - The clutch of the scythe users, and very powerful X.x hurts like hell.

 

[GartarkMusik]

The Explosion finisher in Kingdom Hearts Birth by Sleep. It's even MORE overpowered than the one in KHII. Enemies can't damage you once you start using it, and it does massive damage. I was playing as Aqua when I got this, and I basically became a battle tank. Time Splicer is up there too.

 

[Kopikatsu]

Wish I could remember the name of it, but the super gravity cannon in Super Robot Wars Alpha. That thing would kill everything in it's path. (And I do mean everything...better move your army WAAAAAY off to the sidelines) And it had infinite range with massive spread. It could even one shot the final boss...

 

[Raimies]

The Chicago Typewriter in Resident Evil 4.

 

[TheLastSamurai14]

R-Type Final's Giga Wave Cannon. Everything just dies...

Heartless Angel from Final Fantasy VII, Kingdom Hearts, and other works that Sephiroth appears in. Your MP is completely drained and your HP is reduced to 1. Better hope you have some Megalixers on hand.

The Master-level lightning-elemental Destruction spell from Skyrim. Basically, it's a Kamehameha Wave that burns through any living creature.

 

[Yellowbeard]

Telekinesis in Bioshock.

Uses barely any EVE, and throwing just about anything is a one-hit-kill on a splicer (at least on Medium difficulty).

You can throw corpses, and it doesn't need to be upgraded, so it's basically like having the supercharged Half Life 2 gravity gun for the entire game.
