This morning the news that the Dead Rising demo had gone up on Xbox Live Marketplace was quickly spreading through the internet.
The demo lets you play for fifteen minutes in Paradise Plaza and gives you full access to all the stores therein. You won't see all the weapons, not even all the coolest weapons, but all the same there's plenty of stuff to play with.
After fifteen minutes or if you try to leave the area, you're going to be presented with the game over screen.
The demo is just over a gigabyte in size, so those of you with hard drives crammed full will need to clear up a little space.
