WWE 2K19

| Follow along from the start and you will get the achievement |

Head over to the “Creations” tile on the main menu, and tap down to “SHOW”. From here the only option you need to change is the “Screen Filter” option [right side, 3rd tile down]- Change this from “OFF” to the last option on the list, “CEL SHADING”. I’d advise you to also change the show name, IF you already have other shows created.
Once you’ve done that, press start to save the show.

Now head over to “PLAY” on the main menu and Select: One on One > Normal. From here, press to go into MATCH OPTIONS, and select MATCH RULES. Change the first option, ‘Pin or Submission’ , to “OFF”. Now scroll down to “Finisher Match (perform finisher to win)” and change that to “ON”. Next, press ‘ACCEPT’ twice to go into the 3rd options page, and you can give yourself finishers- change this to ‘3’.
Now press start, and go down 1 option to “SELECT ARENA”. From here, press to view your “created arenas” and select the show you just created (If you didn’t change the name it will be called “RAW”). Select this arena and choose AJ STYLES as your player and face BRAUN STROWMAN, then start the match.

Whilst you’re in the loading screen, click the thumbs up button on this solution

Walk up to BRAUN as soon as the match begins, and press to perform your finisher.(He might reverse if you’re on a higher difficulty)
The match will end as soon as it’s done, and your achievement will unlock when this happens.

Edited to add further detail due to feedback.

To unlock this achievement you need to win a match in an arena which has the 'Cel Shading' screen filter. Firstly, you need a show to play the match in. You can create your own show or download one from Community Creations. To create your own show, from the main menu go to WWE Creations, then choose Show, and New. You can leave everything default but you must change the 'Screen Filter' option to 'Cel Shading'. See Screenshot:

Alternatively, I have uploaded the show in the screenshot to Community Creations. You can find it under my gamertag and/or by searching for 'Jet Set Member'.

Just to emphasise, this needs to be a created show, not a created arena. To my knowledge you can't create an arena with the cel shading effect, it has be done in create a show.

Now for the match. I don't believe there are any difficulty restrictions, I unlocked this on Normal difficulty. From the main menu, go to 'Play' then 'One on one', then 'Normal'. (I would assume this will works with other match types but a 1v1 will likely be the quickest method of unlocking)

Choose your two wrestlers, I suggest using a wrestler with a high OVR and choosing a low OVR opponent to increase your chances of a squash match. I got this with Goldberg vs Gentleman Jack Gallagher.

Press to go to Match Options and go into the Select Arena. Press to go to Custom Arenas and press to choose your created/downloaded arena from there. Press to confirm your options then just play and win the match. Achievement should unlock at the end of the match once you've won.
