You may know exactly which cards your co-op partner should play next in Duo Quest, but do you know their favorite food? What music they listen to? Or which answer they’re going to pick when you’re both put on the spot?
Developed by Malaysian indie studio 1+1 Studios, Duo Quest launches later today after two years in development. The two-player roguelite deckbuilder mixes turn-based battles and card building with more than 1,000 questions covering over 20 different themes.
Matching your answers can give you an advantage in battle, so knowing the person sitting beside you could turn out to be just as useful as knowing what’s in their deck.
The Demon King Has a Bondbreaker
There’s a story behind all those questions. You and your co-op partner take control of two adventurers on a journey to defeat the Demon King, who has been causing trouble across the kingdom using something called the Bondbreaker. Fighting back means making use of Duo Energy, a power tied to the bond between its two users.
During special enemy phases, both players are given questions about each other. These can cover food, music, hobbies, and more personal subjects, with matching answers allowing you to fuse powerful cards together.
There are more than 1,000 questions in total, so remembering your friend’s favorite pizza topping probably isn’t going to be enough to carry you all the way to the Demon King. It might get you through one fight, though.
Two Players, Two Decks
Outside those questions, there’s plenty of deckbuilding to get on with. Both players have their own deck during turn-based battles, working together to take down enemies while building around each other’s strengths. Hundreds of cards can be unlocked as you play, along with five different classes that each come with their own card sets.
Artifacts add more effects to work into your builds, while procedurally generated levels mean you won’t be following exactly the same route every time you play. You’ll get to choose where to head next as you move through each area, deciding which path looks most useful before eventually making your way toward the boss.
Heading back into previously visited areas can uncover secrets and additional cards too, giving you more to find across repeated runs. Just don’t forget you’re supposed to be working together.
Local or Long Distance
Duo Quest was originally built around local two-player co-op, but you no longer need to get both players onto the same sofa. Online multiplayer was added to the demo earlier this month following player feedback and is included in today’s full release. Local co-op and Remote Play Together are also supported, giving you several ways to find out how much your chosen partner actually knows about you.
The turn-based combat should also make things a little easier if the person joining you doesn’t spend quite as much time playing games. There’s no need to keep up with fast-paced combat, and both players have time to think about their cards and decide what to do next.
Whether they’ll have enough time to remember your birthday is another matter.
Two Years Later, Duo Quest Is Ready
Today’s Steam launch comes after two years of development for 1+1 Studios. During that time, Duo Quest was selected for the SEASian Games Showcase 2026 and became a Best Multiplayer finalist at the BIG Festival during Gamescom LATAM. It also previously picked up a Waverider Award at Gamescom Asia.
Next up is Tokyo Game Show, where the full game will be playable from September 17th, just one day after its Steam release.
There’s only one thing left to sort out…Who are you taking with you?
