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

[Extragorey]

Final Judgment in Venetica.
What does it do, you ask?
Insta-kill any enemy, regardless of health or resistances. They just die.

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.

Don't forget W-Summon and Mime. After that I breezed through the final fights.

Slow Time/Gravity Spell or w/e it is via Force Mage skills from DA2 before they patched it, it permanently froze any enemy if you centered the spell on them exactly.

What else... well if you had enough ammo, Vengenace the gatling lazer from FO3. did about 230-250 damage per round and firing at like 30 rounds a second with 100 Energy Weapons. Oh and the Experimental MIRV of course! Whats better than firing 1 miniature nuclear tactical missle?! EIGHT MINIATURE NUCLEAR TACTICAL MISSLES!

Hm... again in FO3 the Gauss Rifle was pretty sick.

If you did the correct Alchemy/Enchanting combo for bows/swords in Skyrim you could do 400+ damage with either weapon.


pffh... all the games ive played and im having trouble thinking...

 

[Clive Howlitzer]

The Farsight in Perfect Dark comes to mind. One hit kill through walls?

Oh man i just remembered Beserk in Fable...ah... loltimes.

In D&D, there is a magic item called a Rod of Rulership that gives the user complete control over the target if it fails a Will save, but if the target has an Intelligence score of less than 12, it doesn't get a save. The toughest monster in D&D is the Tarrasque, it is literally impossible to kill without casting Wish, a ninth-level spell, and it has an Intelligence score of 3. Lastly, there is a Psionic power called True Mind Switch that will permanently switch the minds of the caster and the target. The subjects get all of the physical capabilities of their new bodies while retaining the mental abilities that they already had, such as psionics, for example. While the target of this ability gets a Will save and can apply any Spell Resistance it has, the target can choose to forgo the saving throw and/or lower its Spell Resistance.

When one combines these very interesting facts, the result is an immensely powerful Psion in a virtually unkillable body.

I was gonna say the Redeemer in Unreal Tournament games, but then it does have a drawback (for me anyways), in such that every time I use it I tend to get myself killed as well.

A real game killer is the foam finger unlock in Deadspace 2, but I guess that's the whole idea of it, plus you have to finish the game on max difficulty first before you get to use it so I guess that just means you can best anything the game can throw at you anyhow.

[Trippy Turtle]

Banshee bomb in Halo. Well, that in combination with the back flip. It turns the banshee into an indestructible death machine unless you can convince your team that a DMR actually does damage it.

 

[apprentice150]

Gears of War 3 sawed-off shotgun, just ridiculously strong and too easy to be killed by it.

 

[VoidWanderer]

Most OP ability? Chameleon from Oblivion, especially at 101%. You cannot be seen by anything.

 

[Yeager942]

The Catalyst.

A device so powerful, it single handedly destroys entire franchises, invalidating not only the current playthrough, but every single one in past games. Side effects may include shitty endings.

 

[Portal Operater]

For Pokemon related stuff,

In the Gen I Sabrina was pretty overpowered due to being 15 Levels higher than the last gym, and having psychic Pokemon which pretty much were near unstoppable.

In Gen I the move wrap was a nightmare. Nothing like playing yellow for nostalgic reasons after a very long time and seeing an foe use wrap. Thinking to myself; yep that move sucks... only seconds later remembering that it's unstoppable and my Charmeleon that is like five levels higher than that the foe Bellsprout is pretty much doomed.

 

[albinoterrorist]

G36 in Stalker: Call of Pripyat with third tier upgrades; no recoil, no drift, high rate of fire, pinpoint accuracy in automatic fire and the ammunition is plentiful. Even without upgrades it bests most of the guns in the game. Basically once you get it, its the only gun you need except for a single sniping mission and maybe when killing pseudogiants and chimeras on harder difficulties.

Hmm.
Maybe, but from STALKER I was thinking more along the lines of

Spoiler

the mystical quicksave key

because, honestly, you don't need much else.

 

[notred360]

1.sand attack from pokemon
step 1: use sand attack about 3-4 times
step 2: win!

2.BF3 USAS-12 with frag rounds, anyone who uses it can just go hang

3. smithing in Kingdoms of Amalur reckoning, max that out and anything you make becomes overpowered, turning you into a death machine with gear way past your level.

[kommando367]

I'm going with the Halo Array on this one because it is designed to kill all sentient life in the motherfucking galaxy.

I know it's not technically a video game, but I want to be different so I will choose the D&D 3.5 feat called Vow of Poverty on a Monk. It makes it so that you cannot use any weapons or armor (no big deal for a monk), but gives you really good bonuses every level.

4th Exalted Strike +1 (magic), Bonus exalted feat

I completely destroyed my old DM's campaign with it. Especially since he decided to start using demons against us. Once I fully immobilized a decently powerful demon by reducing his DEX to 0... with my fists... One punch and we were able to just walk up and coup de grace his boss fight.
