That's like way more than getting 0 new maps!

A new update for Team Fortress 2 was released. Included in the update is the addition of 14 new community maps, the Summer 2023 Cosmetic Case with 25 new community-made items, six new community-made taunts, and 20 new community-created Unusual effects.

This update comes alongside the start of the Summer event, which will run until September 15, 2023. This update also includes several different fixes and updates to already existing maps.

Sure, the new maps aren't made by Valve, but 14 new maps being added to the game is still rather neat to see! The full changelog is below and at TeamFortress.com.
