GUNDAM VERSUS

In Gundam Versus, the Player's level is accumulated by the total level of all mobile suits combined e.g. if you have one mobile suit that's level 20, one that's level 10 and another that's level 15, the total player level in this regard will be 45. To view your total player level, go into Battle Record (found under "Briefing Room") and select Player Records. An example of this can be seen in the following screenshot:

Thankfully, unlike the trophies you can unlock by levelling up your mobile suit level to at least level 20, you can use DLC mobile suits to help with this trophy and any of the other trophies above it. For more information on levelling up your mobile suits, as well as a method to easily grind them, please refer to those found in the description for Blazing in the Heavens.
