The Indie Megabooth will make its fourth appearance at PAX Prime later this month, with a collection of more than 70 games from independent developers around the world, the booth's organizers announced today.

Must Read We Built a Booth

The booth will once again feature three different spaces — Megabooth, Minibooth and Tabletop — across a footprint of more than 5,500 square feet on the PAX Prime 2015 show floor. "Nearly half" of the games being exhibited are new to the Megabooth and some are making their public debuts at the convention, the Megabooth's organizers said in a press release.

One of the playable Megabooth games is That Dragon, Cancer, the adventure game about a family's struggle to come to terms with their young son's terminal cancer. Thank You for Playing, a documentary about the game's development, will be screened during PAX Prime at 8 p.m. on Aug. 30 in the Sasquatch Theatre. The screening is open to anyone with a Sunday or multi-day badge for the convention.

A preview of the PAX Prime Megabooth lineup is available in the video above, which is produced like an '80s music video. You can see the full list of games and developers coming to the Indie Megabooth at PAX Prime 2015 on the Megabooth's website.
