About game

Our planet is in peril, surrounded by UFOs, aggressive drones, and lethal comets. As humanity's final shield, you must construct a powerful war machine piece by piece. Each component you choose defines your approach to the battle: install protective shields and robust armor to withstand the onslaught, equip your arsenal with pistols, bazookas, and lasers, add economic modules to generate income during the fight, and enhance your rig with upgrade blocks to increase damage output, firing speed, and reload times. In Sentinels of Earth, each level tests your mettle with 10 relentless survival stages and escalating enemy waves. Between stages, you can purchase new parts and merge duplicates to enhance their power and unlock advanced configurations. Adapt your strategy to the unique challenges of each arena and demonstrate your ability to safeguard Earth!

How to play

The controls are simple, but the gameplay is deep: * Navigate left or right to avoid enemy attacks and meteor showers. * On mobile, slide or press your finger on the screen to move; your weapons will shoot automatically as long as your finger is on the screen. Here's how a level plays out in Sentinels of Earth: * Each level consists of 10 stages. Survive and clear each wave. * Between stages, visit the shop to purchase new parts for your machine. * Combine identical parts to upgrade them and significantly increase your power. * Adapt your strategy to each arena: focus on defense, boost your economy, or maximize firepower to find the most effective combination.
