As we previously reported, Petco underwent some construction changes — but that’s not the only thing that’s changing at Petco, as several of this year’s offsites being held inside the convention are also shaking things up.

We’ve confirmed that Nerdist Industries will be using the Main Concourse along Left Field and the 3rd Base sideline sections, used in previous years by The Nerd Machine and Nerd HQ. Although at this year’s WonderCon, Chris Hardwick announced they’d be using the entire lower level, there was some question as to exactly which area this referred to.

There’s no word yet on what Nerdist has planned for the space, but last year’s Nerdist event was held on the top level of Petco Park, where they teamed up with 2K and Gearbox Software to hold a Borderlands themed laser tag area.

Also making larger use of Petco this year is Walker Stalker Fan Fest, which will be using the Right Field side of the park for the Fest and for The Walking Dead Escape, which will be shorter than previous years but more immersive in the world of The Walking Dead. The Fest will also be using seating along the 1st base side for panels Friday and Saturday of Comic-Con, and also for concerts, including an Emily “Beth” Kinney in concert on Friday, July 10.

During opening week for the San Diego Padres, we were able to explore the construction changes made to Petco Park leading up to the new baseball season. The primary change was the installation of a new, massive, scoreboard:

Nerd HQ attendees are familiar with the area underneath the new scoreboard, Section 130, as the Nerd HQ Main Stage in 2013 and 2014. The section underwent construction in the off-season and had several rows removed to add in bar seating, which was possibly in factor in Nerd HQ’s decision to move away from this particular space.

More information about Walker Stalker Fan Fest can be found at walkerstalkerfanfest.com and you can also enter our contest to win passes (open until May 4). Tickets are also on sale now for The Walking Dead Escape at thewalkingdeadescape.com.
