Not sure about 5pb.'s original Xbox 360 shooter Bullet Soul? While the game is available for purchase as of April 7, those who'd like to try before they buy can do so now via a demo. Xbox Live Gold members have access to the Xbox Live Marketplace demo starting today. Silver Members will have to wait until the 18th.
Those who took part in the national "caravan" score attack tournament for the game will be familiar with the demo, as it features the same two stages.
