About SHALTER-03
SHALTER-03 is a first-person co-op puzzle game where each chapter and characters introduces its own unique mechanics. Taking control of three characters who lack the senses of sight, hearing, and speech, players must work together to overcome these limitations and find the correct solution, all while racing against time to solve each puzzle as efficiently as possible.
Different Puzzles, Different Rules
Every level comes with its own mechanics and rules. Solutions from previous puzzles may not apply to the next. The game is designed to push players to adapt quickly and rethink their approach in every scenario.

Buff and Nerf Systems
Players can use various temporary buffs and nerfs that directly affect how puzzles and the environment behave. Using the right effect at the right moment can make a critical difference when racing against the clock.

First-Person Perspective
The first-person camera creates a direct connection with the environment. Perspective, distance, and timing are essential for both solving puzzles and managing time efficiently.
Race Against Time
Each level has a time limit. Fast thinking, precise decisions, and effective use of mechanics are key. Mistakes cost time, while mastery leads to better performance.
