Activision wants you to “beat the heat” by staying inside and playing more Call of Duty: WWII. Today marks the return of the Days of Summer event.

With heat waves hitting record levels in many parts of the world, summer presents the perfect opportunity to sit inside, enjoy the air conditioning, crack open a cold one and play your favorite video games. Activision is hoping it’ll be Call of Duty: WWII which kicked off its “Days of Summer” event.

As the name suggests, the limited time in-game event celebrates the dog days of summer. It runs from July 31 through August 28 and introduces new weapons, uniforms, cosmetics and the brand new Sandbox map that’ll make you feel like a toy soldier from Disney’s Toy Story.

Available for free, the Sandbox map is exactly what you think it would be – a new map that’s designed like an actual sandbox, complete with sandcastles and beach toys. To go along with the theme, you will play as small, plastic green soldiers that look like they were transported directly from the Pixar movie Toy Story. Sandbox will be available first on PlayStation 4, with no mention of when it will arrive on Xbox One.

Additionally, Days of Summer will make aerial combat available to all players in Dogfighting, a special mode that will see you take the skies above the Egyptian pyramids. Currently, aerial combat in WWII is limited to the War Mode mission Operation Husky, which was introduced in The War Machine DLC pack, so it’s cool that Activision is making this experience available to everyone. Here’s the description:

In Dogfighting, you and your team will take flight over Egyptian pyramids and across mountain ranges while trying to fend off enemy pilots. Shoot down enough bogeys, and you’ll be able to earn Flak Guns that can clear the skies and help secure air supremacy.

Other new additions Days of Summer include three new weapons: the Ribeyrolles submachine gun, the Automation rifle, and the deadly 3-Line Rifle. There will also be Days of Summer-themed uniforms for Master Prestige players, new undead types in Nazi Zombies and tons of new summer personalization options to choose from. This seems to be just the beginning also, as the trailer says more “summertime mayhem” will arrive next week.

Days of Summer isn’t the only thing Call of Duty fans have to be excited about. This Friday, Activision is kicking off a Private Multiplayer Beta for Black Ops 4 on PlayStation 4. Additionally, a beta for Black Ops 4‘s new battle royale mode, Blackout, is coming in September. As you can see, it’s going to be a busy summer for Call of Duty fans and this is only the start of it.
