Unblocked Games: Endless Survival Challenge - Alien Onslaught

Dive into the thrilling world of our unblocked games collection with an adrenaline-pumping io game, exclusively brought to you by Unblocked Games 76, 77, and 6. In this premium, free HTML5 game, you're not just surviving; you're enduring the relentless alien onslaught with one arm against an ever-growing horde of extraterrestrial menaces. How long can you outlast the invaders?

The premise is simple yet gripping: you're a lone survivor, with only one arm and limited ammo, charged with repelling wave after wave of alien monsters. Each new assault brings tougher, nastier adversaries, testing your skills and strategic thinking.

The gameplay is as addictive as it is challenging. Your primary goal? Stay alive, obviously. But to do that, you'll need to manage your ammo and health bar judiciously. Run, hide, or fight, the choice is yours. But remember, every bullet counts!

Now, here's where it gets exciting. Every animal monster you fell leaves behind a coin. Collect these coins to upgrade your critical stats - bullet damage, health points, and movement speed. This escalating power-up system keeps you on your toes, pushing you to improve and adapt in tandem with the alien invaders.
