How to unlock the Invincible man achievement in WWE 2K14 - Definitive Guide
Here is what I found to be by far the easiest way and will only take you JUST A FEW MINUTES and Will not even require you to adjust the sliders!
Go to Options > Gameplay > Match Options > In-Game Options
Change the difficulty to Hard or Legend
Now go back to the Main Menu and go to: Play > One on One > Normal Match.
Pick a wrestler with a Standing Finisher Rock, CM Punk etc. (not off top ropes etc.)
When you hit "A" to select your wrestler an option box comes up that says "Attire and Finishers" go to Finishers and change it to "Infinite" with the D-Pad.
Select any opponent and leave their Finishers at "None"
When you get to the match-up screen goto "Match Creator" go to Win Condition and go to "Finisher Match" and change it to on.
When the match starts simply walk to your opponent and hit "Y" ....MATCH OVER!
When the final screen comes up just hit "Rematch". You don't even need to leave the match! Your achieve will pop up on the final ring of the bell following your 20th victory. Should take you no longer than 10 minutes. Hit start to skip replays for added efficiency. Any questions please message me. If you vote negaitvely please explain why and give me a chance to adjust it.
I went into Play mode, and I chose my Custom Superstar. I made all matches Hard, and I changed all the matches to Finisher Matches.
After that, I would make me have infinite finishers, and just leave your opponent.
If you have Mr. McMahon, it's pretty easy, especially if your finisher is a running spear.
Now, as for how to set this up to do this:
Difficulty: Options > Gameplay > Match Options > In-Game Options
Setting up Match: Play > One on One > Any match type ( I chose Extreme Rules, just because )
Setting up finisher settings: Select your person, change your starting finisher amount to infinite.
Hit Your Finisher right away. ( I used a running spear. Just saying. )
And that is 1 down, 19 to go. Just rinse and repeat.
Make sure the match difficulty is set to hard or higher, and win 20 times. I suggest giving the Superstar you play as infinite finishers, as well as turning the K.O. option on. After 4-5 finishers your opponent should be knocked out. Hit rematch until you've reached your goal.
Tip: Use Big Show as he has the Knock Out Punch. It makes things a bit easier. See this video if you're having trouble (credit to DANALL3N for the video):
Years of WrestleMania or go to options and change difficulty to Hard, then create a 1 on 1 match and change your wrestler's finishers to infinite. Select match rules and change to win by finisher. When the match starts hit your finisher which will result in a win by KO. Hit rematch. Rinse and repeat 20 times.
