Publisher TARK and developer Lefto Studio announced on August 12 that the three-player co-op bomb defusal game BOMBANANA! will launch on Steam on September 2. The release time is not yet fixed, so it may become available in the early morning of September 3 Japan time. The game is built around the three wise monkeys motif: the blind monkey can touch the bomb but cannot see visual information, the mute monkey holds the defusal manual but cannot speak or use chat, and the deaf monkey can see everything but cannot hear. Players must build a communication chain through gestures and body language to defuse bombs before the timer runs out. The demo, released during Steam Next Fest June 2026, has been played by over 6 million people and added to more than 1 million wishlists. It also holds an Overwhelmingly Positive rating on Steam from over 5,000 reviews. The full game will include a free mode where players can design their own bombs. The price is undecided, and the game will support 15 languages including Japanese.
Lefto Studio is an indie studio based in Istanbul, Turkey, founded in 2025, and BOMBANANA! is its debut commercial title. The development team, led by founder and producer Ufuk Girit, includes staff who previously worked on similar party games such as Liars Bar and We Are So Cooked. Girit said, "I was confident the game would succeed based on its fun factor, but being number one at Steam Next Fest was a real surprise."
The game's asymmetric roles force players to rely on restricted communication. The mute monkey can only gesture, the blind monkey reads braille and touch, and the deaf monkey relays instructions. There is no fixed answer for how to build the communication chain, and the game includes role-limited voice chat. Bombs contain modules with different rules, and clearing stages unlocks higher difficulty levels. The free mode lets players design custom bombs to challenge friends.
For market expansion, TARK is working with publishing veterans Claire Barilla and Steve Stopps, who have experience with titles like Ranch Simulator and Still Wakes The Deep. The product version also updates the art style, using watercolor-style brushes on 3D models to create a hand-drawn look, and adds comic-style UI with mouth animations in the lobby so players can see who is speaking.
