In Command & Conquer 3, it would be the Planetary Assault Carrier for most.

In Jedi Knight II: Outcast and Jedi Academy, jumping high and then Force Pulling enemies from the ground.

"It's raining men! Hallelujah! It's raining men..."

Also, it's raining men and pieces of men if you have cheats on.

IDKFA/IDDQD

Oh, and crossbow sighting in Half Life and the Clone Vats in Alpha Centurai.

In Red Alert 2, building a wall round the barracks when you have a cloning vat so men are free.

The whole of Mercenaries two, and by favourite I mean I hate it with all of my heart

Firing the charged laser at the edges of the map/level instead of targeting specific enemies. 500 kills per level? That'll do nicely...

The Missingno cheat on Pokemon Red/Blue.
Happy, cheaty times...

I was actually REALLY SCARED of that thing =/ Oh God, and if you were foolish enough to capture one (like me) ... the things... the horrible, horrible things...

ty for all the rare candys though Mr. Missingno...

Any EA football game and the tight end quick slant over the middle for the cheapest seven yards in gaming.

Come to think of it the TE quick slant is one of the oldest tricks in the book considering there was an unstoppable play in Tecmo Super Bowl that worked on the same principle---even when the computer called it and blitzed, you could still flick your fingers over A-B and salvage seven to ten yards out of it.

Not a glitch or anything, but in FF7: Crisis Core you can max out the ATK (attack) stats on a Materia by endlessly fusing the Coffin Keys item (Found in the shinra mansion basement). The two materias that you fuse have to not change the one you want to max out though. ie:

- Death Twister: Atk + 20
- Atk+: Atk + 1

That will just keep the original materia in-tact, "Death Twister: Atk + 20". fuse it with 4 Coffin Keys though, and it becomes "Death Twister: Atk + 24" you can keep doing this so long as you have enough SP to fuse, and you can also only obtain 4 coffin keys at a time. I've got mine up to about Atk + 90 at the moment.

Using noclip to enter into the active-render skybox environments in any game using the Source Engine.
Yeah.

Yeah.

I've never played TF2, but... what's the cheat? You use noclip to run outside the boundaries of the map... so... please explain?

That got patched pretty damn quick though.

The Tag! perk glitch in Fallout 2. Save your skill points throughout your levels until you get to level 12 with 99 points. Then spend them all on an untagged skill. Tag! said skill, then you can subtract points from it and distribute them to your other skills. You'll end up with more points than what you put in to the skill originally.

In Oblivion where you pucnh or shoot and arrow as you're dropping a soul gem and getting a gazillion of them.

Getting Mew in pokemon red and blue.

Fuck me, thats a blast from the past. Didnt you have to swim up and down an island like 50 times and then fly to a cave? I'd love to meet the person who discovered that if they ever leave the house.

That reminds me of the way to unlock master hand in the first super smash brothers. You had to rotate the analog stick like a hundred times or something insane, and you could unlock him (it?) and it was found out by someone who was probably just sitting at home, rotating the analog stick out of boredom. Just ... what the hell, dude at Nintendo that created that. XD

I personally like the fact in KH1 you can throw a crate at Goofy and he'll yelp and it'll break. XD;;
