TwinLock

Two-player co-op

TwinLock is a PC co-op puzzle adventure for exactly two players. Two paranormal investigators from the Echo agency enter Castle Verathorne to investigate disappearances, but the abandoned gothic castle separates them. There’s no single-player mode or bots: each player needs a working microphone and an internet connection.

Puzzles across the walls

You and your partner never see the same room at the same time. You communicate by walkie-talkie, describing what you see rather than sharing a screen or pointing. Each of the eight puzzles divides its answer between you: one player might have levers while the other has symbols, or one might see a chessboard while the other has to cross it. You’ll need to explain shapes and clues clearly to make progress.
