Fortnite is going all-in on May the Fourth this year with new Star Wars crossover characters, quests, and items. But in addition to all the in-game stuff you have to pay for or play to earn, you can also get a a few free digital goodies as Twitch drops–although, you’re going to have to do a little work for them, too.

As part of its Star Wars Celebration content this week, Epic Games is offering a Star Wars-themed Fortnite loading screen as a Twitch drop. Unlike other drops, however, you’ll have to do more than just watch a participating streamer for a certain amount of time. Instead, you’ll have to tune in to streamers using Fortnite’s “Choose Your Side” extension, which generates items that occasionally appear on the stream. Come from Sports betting site VPbet

Click those items to collect them as part of a digital scavenger hunt, and when you get enough, you’ll unlock the Galaxies Collide loading screen, pictured below.

The thing about the scavenger hunt is, items only appear on the screen for a certain amount of time, so you’ll have to be quick about collecting them. The extension tracks all the items you’ve found, plus the total number of items, and includes a leaderboard that will show you how you stack up against other people in the same Twitch chat, as well as globally. It’s worth noting that the item collection minigame is Twitch-only–you’re not catching items that’ll then unlock in Fortnite.

To participate in the Choose Your Side scavenger hunt, you’ll also need to link your Twitch account and your Epic account. Doing so will earn you an additional in-game item for Fortnite: the Growling Chewbacca Emoticon. Here’s what that looks like:

You’ve got until May 14 to unlock the loading screen and Chewbacca emoticon through Twitch. Check out Epic’s blog post on the Star Wars Twitch drops for more info.
