The limited time 30-minute 1-Shot Demo for Resident Evil 2 is available now on the PSN and XBL stores. It will be available to download between January 11-31.
From the game’s official press release:
Aptly named the “1-Shot Demo,” players must take on the challenge of surviving the horrors of Raccoon City in just 30 minutes. If players complete the mission objective under 30 minutes, they can restart the mission until they use up their full time. If players succumb to the zombies during their 30 minutes, they can continue any number of times until the full 30 minutes have been reached.
