Link & Lock - Sem Saída

Link & Lock - Sem Saída is a cooperative horror game built around voice interaction: using your microphone helps you navigate the derelict Santa Margarida Sanatorium but also risks attracting its audio-sensitive antagonist. In this two-player experience you and a partner must restore power, find four hidden key cards and use a voice seal mechanic to open the exit while managing noise, sanity and scarce resources. The description below explains the gameplay, controls, progression and technical considerations to help you decide whether this development test build fits your setup.

Core gameplay and mechanics

The core mechanic in Link & Lock - Sem Saída turns communication into gameplay risk. Players speak to coordinate tasks such as exploring rooms, solving simple environmental puzzles and performing lockpicking or item interactions; any vocalization, from whispers to loud shouts or heavy breathing, can be detected by enemies and change their behavior. Procedural generation creates varied floorplans on every run, and a sanity system modifies visual clarity and flashlight stability as stress increases. Enemies are audio-reactive: they hunt by sound, remember investigated locations and respond to environmental triggers like slamming doors or sudden light changes.

Controls and interaction

Designed for PC controls in its current test build, Link & Lock - Sem Saída uses standard movement and interaction inputs alongside the microphone as a gameplay resource. Movement and camera control are typically handled with keyboard and mouse, interactions include picking up items, using a taser or melee weapon and activating the in-game voice seal at the exit. There are limited melee and stun options—examples in the build include an iron bar, a machete and a taser—which provide short windows to evade or stall an enemy, but combat is deliberately constrained to preserve tension. Use the F8 key in-game to report issues during testing; this generates a log and screenshot to help the development team diagnose problems.

Progression, challenge systems and replay value

Each run in Link & Lock - Sem Saída is compact and focused, targeted at roughly 20 minutes of play. Progression is session-based rather than persistent: players learn through repeated runs, discovering map patterns, audio cues and effective communication tactics. The procedural maps, combined with reactive AI and randomized item placement, create high replayability and emergent moments that differ each session. Challenge scales through map variety, enemy memory and the sanity mechanic, encouraging players to balance exploration speed with careful noise management. Because this is a development build, expect tuning changes and varying difficulty as the team iterates.

Level structure and visual style

Levels are composed of modular rooms—cells, morgue, operating theatre, archives and similar spaces—assembled into different floorplans each run. The visual approach blends moody, atmospheric lighting with practical, utilitarian set dressing to support environmental storytelling: notes, posters and graffiti provide fragments of the 1963 incident that led to the sanatorium's downfall. Lighting is used as both ambiance and gameplay signal, with flickering fixtures and intermittent power influencing route choices and danger assessment. A reduced-flash option is included for players sensitive to rapid light changes.

Customization and user experience

While the current test build focuses on core mechanics rather than deep cosmetic customization, there are useful in-game options to tailor audio sensitivity, microphone input levels and visual comfort settings. Players can adjust sound thresholds to reduce false detections and enable accessibility features that stabilize the HUD and flashlight behavior. The interface emphasizes clarity during short runs, with concise objectives and a simple inventory display to avoid unnecessary distraction from cooperative tactics and atmosphere.

Accessibility, offline play and technical notes

Link & Lock - Sem Saída requires a working microphone for full functionality; silent play is not supported because voice use is central to progression. Local offline cooperative play is not available in this test build: online play requires an internet connection to reach dedicated servers. The build targets Windows 10/11 64-bit systems and a dedicated graphics card is recommended for a stable frame rate. There is a photosensitivity warning and an option to reduce flashing effects for players who need it. As a test release, the team welcomes bug reports and feedback to improve accessibility and performance.

Known limitations and reporting

This release is a development test build: players may encounter bugs, performance variability and balancing issues. Please use the F8 reporting function to capture logs and screenshots and use the in-game diagnostics option to submit reports if available in your pause menu. The developers are actively iterating on enemy behavior, sanity effects and procedural generation parameters based on player feedback. If you enjoy communication-driven tension, emergent scares and replayable short sessions, Link & Lock - Sem Saída offers a focused cooperative horror experience that emphasizes sound, stealth and teamwork during each run.
