The Games4Green – Cloud Invaders is a fast-paced arcade shooter designed to raise awareness about air pollution. Players control a planet that must defend itself from waves of toxic pollution clouds. These clouds drop harmful bombs, and the player must shoot them down before pollution overwhelms the planet.
Unlike traditional shooter games, Cloud Invaders replaces alien invasions with pollution as the enemy, reinforcing the dangers of airborne contaminants. Players move the planet left and right while firing at the pollution clouds, aiming to destroy as many as possible before the atmosphere becomes too polluted. As time progresses, the clouds attack more aggressively, making the game increasingly challenging.
The game mechanics reflect real-world environmental concerns, such as industrial emissions, vehicle exhaust, and climate change. The rising difficulty represents how pollution worsens over time if not addressed. Players experience firsthand the urgency of environmental protection, as delaying action leads to overwhelming pollution.
Technically, Cloud Invaders is built using Phaser.io, a JavaScript-based game engine. The game includes animations for clouds, enemy shooting mechanics, and collision detection. Players fire bullets using keyboard or mouse controls, while enemies launch randomized pollution attacks. The game ends when pollution reaches a critical level, symbolizing the real-world impact of unchecked pollution.
Beyond entertainment, Cloud Invaders serves as an educational tool, encouraging players to consider how small actions, like reducing emissions and supporting green policies, can help fight pollution. The game combines fast-paced action with an environmental message, making learning about air pollution interactive and engaging.
