Not only is this achievement the most grindy in the game but it also has a tendancy to glitch (it appears to be a problem with the achievement tracker app) so here are some helpful tips to save you from having to do a 2nd playthrough:
- Stick to one suit at a time until it's fully levelled up (Max level is 8).
- Have the achievement tracker app snapped to the side of the game. Everytime you level up and glow green the app should increase 1% (sometimes 2%). If it does not go up at all then that level of the suit has glitched and you will need to do something about it.
What I did was everytime I levelled up I paused the game so that it wouldn't auto-save. If you notice that there was no percentage increase (it happened to me on my last level of the Scarlet Spider & Big Time suits) then hold the guide button and turn the console off straight away.
After restarting it should show the correct percentage but if it shows the wrong percentage then you will need to level up the suit again. You should be the level you were before the glitch occured.
- To help keep track of what percentage you should be at here is a list of what they should be when each suit is maxed out:
1st Suit: 7%
2nd Suit: 15%
3rd Suit: 23%
4th Suit: 30%
5th Suit: 38%
6th Suit: 46%
7th Suit: 53%
8th Suit: 61%
9th Suit: 69%
10th Suit: 76%
11th Suit: 84%
12th Suit: 92%
13th Suit: 100%
- Occasionally the achivement tracker app would, instead of going up, will go down a suits worth of progress (i.e. I would be at 69% and then it would drop to 46%, 23% and even once 0%). If this happens then pause and restart the console. It should fix itself.
That's about it; use the guide posted by Ecko3351 (it took me about 40 minutes per suit personally) to boost those levels and I wish you all good luck with this achievement.
