We’re delighted to announce that we’re teaming up with Re-Logic for some exciting crossover activity. Core Keeper and Terraria are both sandbox games with a focus on exploration and adventure, and we’ve been in discussion with Re-Logic for a little while now about ways that we could come together to celebrate both games with our respective communities.

Make Way for King Slime in Core Keeper

We can now reveal that, from the 26th of September, you’ll be able to summon a creature you’ll recognise as one of Terraria’s (pre-hardmode) heavy-damage dealers. That’s right, say hello to King Slime.

This giant, royal blob doesn’t just spawn randomly, however. In fact, he’s a little bit like Omoroth in that you’ll need to summon him forth when you want to battle. “How do we summon him?” you ask. Well, that’s for us to know, and you to find out!

Battling King Slime may be a challenge, but it could definitely be worth your while. Rumour has it that defeating King Slime will score you some pretty interesting loot that will make you the envy of your fellow explorers

Domesticate a Caveling in Terraria

Cavelings are usually very hostile creatures, especially towards adventurers. That being said, there are one or two Cavelings that have proven friendly in the past (like the Caveling Merchants). It’s safe to say that Cavelings can be good company, in the right conditions, and it looks like you’re going to be able to make friends with one in Terraria.

Introducing the Caveling Pet, a friendly Caveling Farmer that’ll follow your character around looking cute and offering a little moral support wherever you go. You’ll be able to summon this uncharacteristically docile Caveling in Terraria using a special item that you’ll also recognise from Core Keeper. We think it’ll be more fun for you to figure this one out yourselves, so we’ll say no more on the matter!

While we’ve done timed events in the past, we’re pleased to report that the Core Keeper and Terraria crossover is permanent! This means you’ll be able to summon King Slime and/or make friends with a Caveling at your leisure. This crossover comes as part of a much bigger update for Terraria too, and we hope you’ll join us in wishing the developers a huge congratulations on the update.

We’re still hard at work on our next major content update, The Desert Biome. While we haven’t released any details on this yet, make sure you keep an eye on our Steam news page, Twitter, and Discord for announcements. Until then, we hope you have fun tackling King Slime in Core Keeper, and we hope you enjoy your new Caveling pal in Terraria.
