A new Fortnite demo was shown live on state at the Apple Worldwide Developers Conference (WWDC) earlier this month, and the team at Epic Games released it to YouTube just yesterday.
The in-game demo shows off a cuddly, brightly colored world where purple stormclouds fling waves of gruesome enemies against small groups of players.
"If you've ever built a pillow fort or battled imaginary monsters with your friends you already know how to play Fortnite," said Billy Bramer, lead gameplay programmer on Fortnite. "This is the end of the world scenario you've been training for since you were a kid."
The demo shows off the game's third-person perspective, as well as an unusual set of weapons including a broom and an acoustic guitar. Players venture out into the world to gather resources by wailing away at things like cars and trees, then bring them back to their base to build fortifications.
Fortnite is in closed alpha right now, and Bramer said the beta will start this fall. For more on Polygon's hands-on time with the game, check our our article here.
