Gundam Breaker 2′s demo is now available to download on the Japanese PlayStation Store for PS Vita.
With the demo, players are not only allowed to play with other players who have the demo, but with those who own the retail version as well. Just like the retail version you can play together through ad-hoc or online multiplayer. If you decide to purchase the full game afterward, your save data from the demo will be compatible.
You can download the 1.5GB demo here.
