SOS MAR is a digital game whose focus is to playfully engage the player in the process of environmental preservation. In a scenario that simulates the bottom of the sea, with all its diversity, the player's mission is to navigate the ocean aboard a submarine, collecting garbage and other debris thrown into the sea by polluting ships.

The goal is to collect as much waste as possible, avoiding the accumulation on the seabed. But the player needs to be careful about sudden shark attacks and the submarine's oxygen level, triggering refueling when necessary. The player will also have an extra strength from the mascot of the Sustainable Development Plan of the Municipality of Rio de Janeiro.
