I went into Gamestop yesterday and they had many copies of Monster Hunter Tri demo that they were giving out. The demo comes with a map of controls for each class. This is a heads up to demo collectors, and people that want to check out the game early.
Essentially the game demo lets you check out the different classes in the game and play a timed amount of time.
This is easily my most anticipated game this year, and one that I am getting day one.
