WHAT? Damn. You can't even max it out replaying missions either?
Edit: Also... you were still able to get 1000 / Platinum weren't you? Now that I look at it, I don't see an achievement for maxing out your Triad level.
Psst...
Ultimate Fighter
Unlock ten Triad Upgrades.
That means earn enough XP to reach Triad Level 10, cause 10 locked upgrades get unlocked
Same goes for Super Cop, but it's easier
I told ya to buy in-game store items
It's in the city area (Central?) store starts with an A, its located right near a ramp to the highway, it's the same store where you pick up your suits for the Wedding (mission)
The Mountaineer set, it adds 15% bonus if you wear the whole set (shirt/pants/boots)
You can replay all the Triad missions with that set on, increase your overall score to boost your XP
Thing is once you start filling those 3 Red Triangles and your score isn't way higher like +500 than the last time you played the mission, yu will gain minimal xp, and you will get assed out of cheev
Then you really need to buy DLC, 2 versions a Silver or Gold Pack, pricey shitty DLC
Funny enough if you had pre-ordered @ Gamestop, you earned a bonus mission, where you go back to the monks temple, you can play that infinitely and get rewarded handsomely in Triad XP
The clothes appear roughly 35% into storyline, so buy ASAP, play missions with it on
Then when finished (see which missions you did horrible, like half to a 1 full triangle filled, replay those, score high (hopefully you have unlocked all combo moves and wei is wei'd the fuck out)
Never repeat combos, always do something else
Doing the same arm break move will get you less and less points
