Tsunamis.io is a multiplayer browser game that combines survival mechanics with resource collection and base management. The player enters a shared 3D map where natural disasters occur at regular intervals, forcing constant movement and decision-making. The main objective is to gather resources, return them to a safe area, and convert them into long-term income while avoiding large tsunami waves.

Environment And Risk System

The game takes place in an open map divided into safe and dangerous zones. Areas close to the starting point contain basic resources, while more valuable items are located further away. Moving deeper into the map increases potential rewards but also raises the risk of losing progress due to incoming waves.

Tsunamis act as the primary hazard. They appear without long delays and can reset progress if the player is caught in the open. This creates a constant need to evaluate distance, timing, and return paths. The environment remains active, and players must continuously adjust their position.

Core Gameplay Loop

The main loop is built around collecting, securing, and upgrading resources while managing risk.

• Exploring the map to find valuable items
• Carrying collected resources back to a base
• Converting items into passive income
• Avoiding tsunami waves and hazards
• Repeating runs to improve efficiency

These actions are repeated throughout each session. The player advances by optimizing routes and minimizing losses during collection cycles.

Multiplayer Interaction

The game includes a competitive multiplayer system where players share the same environment. Interaction is indirect but constant, as others can influence resource availability and safety. In some cases, players can interfere with each other by targeting unsecured resources.

This creates a dynamic environment where strategy depends not only on map awareness but also on observing other players. Decisions such as when to return to base or which route to take are affected by the behavior of others in the session.

Progression And Upgrades

Progression is based on accumulating currency and investing it into upgrades. These upgrades improve movement speed, carrying capacity, and overall efficiency. Over time, the player can access systems that allow resetting progress in exchange for long-term bonuses, increasing future gains.

There are no fixed levels or missions. Advancement is defined by how effectively the player manages risk and improves their collection strategy. Each run contributes to gradual development.
