(Europe server only) play the SHAPE BLAST game (upstairs) in the Presentation space (gamescon going on right now) to win the Shape Blast trophy (VERY cool - best trophy yet). NOTE: the game consists of shooting cannons at red hoops - it is not easy at first. Took me about 10 times to get the trophy.
This game will sometimes freeze, to prevent this, use the 6th cannon first (closest to the start point). You must exit the Presentation Podium and come back to refresh to avoid crashing if you don't beat it right away.
