I just got the platinum on ps3. I was able to do 90 challenges against AI and I boosted the remaining 10, although I think all are doable offline. Below I will post the challenges I recommend to be boosted as they are a bit annoying against AI or notably faster online. Platinum on ps3 is a bit longer since now you only have 100 challenges and some are quite long but easy nonetheless. A fair estimate would be 20h for PSV and 25h for ps3 version, considering that you boost the challenges below. Boosting other challenges doesn't really make a difference as they are easy against an AI but if you have an extra copy it doesn't hurt to boost them too.
Challenges I recommend that you boost are (boost takes like an hour per person):
- Wrestling#7 & kickbox#7 & savate#5
150/200 step strikes, it's just too annoying to perform against any AI, boosting solution is below (Mauy thai #6).
- Judo#4 & Karate#3 & savate#2
Interrupt 10/15 attacks. Press down+tringle, and then quickly press up+triangle with alt
Break their legs. Just hold down and keep pressing triangle every second, then for the last few hits activate adrenalin.
Character Mastery. The most annoying one, do 10 standing hits/kicks, 3 clinch strikes, 3 ground strikes, 1 successful submission attempt, 2 throws, have a 70% hit rate, and finish with highlight KO. This one is a bit buggy so keep trying. One thing that worked for me on vita especially was finishing an opponent with a highlight submission.
- Muay thai#6
15 step strikes in one match. For step strikes hold R1 and press forward twice+triangle/square
- Muay thai#7
1 minute in Muay thai clinch. This one was annoying to figure out, press up+X so you get in Muay thai clinch. Now stay there the whole time, have your alt/boosting buddy slowly press square every few seconds, hold up to block, and throw a few punches in between.
- Muay thai#10
Character Mastery. Press up+X (Muay thai clinch) and then attack slowly with a square for the whole game in the same position, finish the opponent while using adrenalin, and the same attack (square).
I also have a few tips for challenges you can do offline, some were quite tricky to figure out as all guides out there are very vague or don't even contain the required information. I'm not posting this in ps3 version forum because it applies to the PSV as well and I don't want to start another topic just for that.
Note: When I say pick boxer as an opponent I mean "Jens Pulver" he is much better than the other boxer. He is great for grinding challenges so use it for almost all of them.
- Boxer #10
Spam down+square against St. John or Boxer.
- Kickboxer #10
Fight against a boxer, always block up, wait for him to do his attack, and then quickly press square twice, repeat
- karate #10
Pick boxer as an opponent, always block up, wait on him to finish the attack, then quickly stop holding up and press square 3 times, the opponent will fall on the
ground, go close and press square again to attack him while he is on the ground, then start blocking and repeat. Keep in mind that you need a 70% hit ratio so
don't waste punches and you will be fine.
Pick boxer as an opponent and block up, wait that he attacks, and then do 2 up kicks, start blocking and repeat. Finish the opponent with up kicks while using
- jiujitsu #10
Put the enemy on the ground, stay there for the whole fight and try to be in a position where you can do arm submission(both turned in the same direction), just
spam submissions, for the first few wait a little bit in submission hold so you don't do a lot of damage with it but you injure his arm instead, then once his arms are injured (red in the top corner) finish him off with another arm submission while using adrenalin. Keep in mind that you are not allowed to do any other attacks.
- Ground transition blocks, press down a couple of times so you are on his back, then lock on screen, and when you see X on-screen press is to block
- For X parries or counters just pick boxer as an opponent and always hold up and then press circle to parry(and square/triangle to counter)
- For counter blocks, I played against boxer too, just attack with square and once he parries spam circle
- For farming throws play against a boxer as well
- Beat all fighters with highlight KO is easy, I recommend that you put an enemy on the ground and you smash their head, also keep a list of names of fighters you
already highlight KO-d.
- 60 standing strikes, fight against a boxer, always block up, wait for him to do his attack, and then quickly press square twice, repeat
- 15 minutes in the down position, just throw the enemy and spam up/down till the end of the match
- For 15 grapple strikes, this one is a bit buggy but basically press down+X and then up/down/left/right+X, switch it up a little bit, that seemed to trigger it for me
- The fastest way to win matches is to put an enemy on the ground and spam submissions, if the fighter can't do that get in clinch position (down+X) and spam
square/triangle and repeat.
- 100 buckets of blood. For this play against "Demian Reis", if you play as Savate class put him on the ground with 3 punches, press down+X, once you are on top of
him smash his face until there is blood everywhere. This one can take a while. For MMA class it's way faster and you can put an opponent down with a throw.
- 100 kicks in the down position. This one is a bitch both online and offline. I played against the boxer and spammed the square, he eventually countered my attack
and smashed me to the ground, from there I pressed the square and did the attack in the down position, then I did that 99 more times. If the enemy isn't countering,
try going a few steps back and press square a bit slower.
For other challenges, you can look up my PSV version checklist but the rest are quite self-explanatory. For other #10 challenges, you can use this guide too: https://bit.ly/36b3YhV
Only the ones above didn't work with the strategy from the Xbox guide. That's it, if you have some tips yourself don't hesitate to post them, good luck to anyone attempting this! I found the game quite fun for the most part and way easier than rarity suggests.
