If you read the headline carefully enough, you'll notice that there is more than one demo coming out for the upcoming PSP Half-Minute Hero. However, the first demo will be available on the PlayStation Store tomorrow. It's quite possibly the zaniest game to hit the platform in a long time, forcing players to vanquish evil in 30 second bursts (seriously!). Hero mode is just one of four different modes hidden in the full game.
It's hard to effectively describe the frantic gameplay through words. Thankfully, you can completely ignore our opinions and just give the demo a spin.
