It is very common for online games in Japan to team up with popular animes, and Phantasy Star Online 2 will be doing so again by having a collaboration with Attack on Titan. Later this month, players will get to purchase cool new costumes and hairstyles to match those of the main characters’.
If you are wondering, the weapon skin is actually for an existing weapon, the twin sabers. The main lobby for Phantasy Star Online 2 will also be decorated with a Titan, along with several other images/ posters. Seems really cool, and this will definitely not be the last anime to appear in the game this year.
