Zoned areas offer different things for visitors like artist competitions, speed runners going head-to-head in gaming pods and the latest Sonic titles "are available for fans to try".
Publisher SEGA has also confirmed that the San Diego Comic Convention will host the Sonic Boom event on July 13th, which requires no SDCC credentials to enter.
"SoS is an all-day event that celebrates all aspects of the Sonic franchise. 'Zoned' areas offer a range of different activities - budding artists can sit down at the fan art tables and compete in competitions, speed runners can challenge each other at the retro gaming pods, and the latest Sonic titles are available for fans to try before they're even released."
Both venues should have Sonic 4: Episode II on-hand to play.
