Earth Invaders is a classic fixed-shooter arcade game where you control the last line of defense against a descending alien fleet. This HTML5 browser game challenges you to pilot a cannon at the bottom of the screen, firing upwards to destroy waves of extraterrestrial threats.
It's a straightforward skill-based shooter reminiscent of titles like Space Invaders, perfect for players looking for a dose of retro action.
The core gameplay of Earth Invaders revolves around surviving and eliminating all hostiles on the screen. You must move your cannon left and right to dodge enemy fire while strategically shooting down the organized rows of invaders.
The entire alien formation marches back and forth, dropping down a step each time it reaches the edge of the screen.
As you destroy more invaders, the remaining ones increase their speed, making them harder to hit and their descent more rapid. Your goal is to clear the entire wave before they can reach the bottom of the play area.
The game features five levels, with each presenting a full new formation to defeat.
You aren't just shooting at static targets. The invaders will fire their own projectiles down at you. You start with a limited number of lives, and you'll lose one if your cannon is hit or if a single invader touches the ground.
To help you survive, there are four destructible shields positioned above your cannon.
These barriers can absorb both your shots and enemy fire, but they degrade with each impact. Using them wisely is key to surviving the later stages of a wave when the enemy fire becomes more intense.
You must balance offense and defense to become the hero Earth needs.
You can play Earth Invaders for free directly in your web browser. There's no need for any downloads or installations.
Because it's an HTML5 game, it runs on most modern devices and can be accessed on networks at school or work, letting you jump straight into defending the planet whenever you have a spare moment.
The main objective in Earth Invaders is to destroy every single alien invader in each of the five levels to defend the planet. You must clear the entire formation before any of them reach the ground.
Control your defensive cannon using the left and right arrow keys to move horizontally along the bottom of the screen. Press the spacebar to fire your laser upwards at the alien fleet.
You have a limited number of lives. You will lose a life if your cannon is hit by an enemy projectile or if an invader successfully lands on the ground. The game ends when you run out of lives.
Use the four protective shields to block enemy fire, but be aware that they will be destroyed after taking several hits.
Stay on the Move - Don't remain in one spot for too long. Constant movement makes you a much harder target for the invaders' shots. Use Shields Strategically - Try to shoot through the gaps in your shields to preserve them.
Save them for when the last few invaders are moving very quickly and firing rapidly. Clear the Edges - Eliminating the invaders on the far left or right first can give you more time before the fleet reverses direction and drops down.
Focus Fire - It's often better to clear an entire vertical column of aliens. This creates a safe channel where you can momentarily avoid enemy fire. Time Your Shots - You can only have one of your lasers on the screen at a time.
Wait for your shot to hit a target or go off-screen before firing again to maximize your rate of fire.
