The Street Fighter trophies consist of 26 offline achievements (21 bronze, 3 silver, 2 gold), and 19 online ones (14 bronze, 2 silver, 2 gold, 1 platinum).
The main thing you need to get the trophies is to just play. You will probably get achievements offline first. This is facilitated by the relative ease in passing Story mode.
The most difficult trophy here is gold back from hell. To do this, you need to defeat 100 enemies on the highest difficulty level.
The health bar can be restored after each completed stage, but it costs money, so you need to be careful when using it.
For the next really hard achievement, you need to play at least 300 Ranked Matches and Random Matches in total. You can also get lighter trophies in parallel, for example, for one of them you need to get 50 repetitions. Basically, such trophies only take time. Another example of such trophies is a challenge that requires reaching level 30 with a character or reaching player level 200.
The hardest part for you can be at the very end of the Grinding trophies from whole SFV trophy guide.
So, you are going to repeat final moves many times along with special moves and V-Moves to achieve some of the more time-consuming trophies the game has.
It's highly recommended that you work on all these trophies while you play Story Mode, Survival Mode, and Online Mode so the grind would take a little less time.
It is important to note that some Street Fighter V trophies may not appear if you are playing offline or without the latest patch installed. Therefore it is recommended to install the latest patch and always play with server connections.
It's important to take note that some Street Fighter 5 trophies may not pop if you are playing offline. You can suddenly lose connection to the servers and this may cause you to have to replay the same stage you were on after signing-in again, especially with the trophies regarding reaching level 5 with all characters.
We wish you good luck!
