Have you ever wondered what Curious Expedition would be like as a massively multiplayer game? Make sure to play the new RIVALS mode we launched today to find out!

Here are some of the things you can expect from RIVALS:
Explore worlds that are up to 10,000 times larger than in the original game.
Discover new regions and have your name and portrait remembered for all other players to see.
Acquire prestigious badges with every golden pyramid you discover.
Equip your trek with over 140 Expedition Crates to customize your playstyle and experiment with different strategies.
