undead invasion

If you're into fast-paced  shooting games , you should definitely try Undead Invasion. It's a side-scrolling zombie shooter with pixel graphics that keeps you on your toes from the first wave. The shooting mechanics feel satisfying, and you get access to various firearms that you can upgrade between waves. Plus, the game adds tactical depth with melee combat and grenades for different situations.

The wave-based progression means the action never stops. Each day increases the zombie count and difficulty, so you're constantly testing your aim and reflexes. The game rewards precision shooting while also requiring strategic thinking—knowing when to use ranged attacks versus when to switch to melee can mean the difference between survival and starting over.

What makes this shooter stand out is the defense element. You're not just shooting; you're placing barricades and traps to create chokepoints and slow down the undead. This adds a strategic layer that many pure shooting games lack. The controls are responsive, the pixel art is well-done, and the difficulty curve keeps you coming back to beat your high score. It's completely free and runs smoothly in any browser—perfect for a quick gaming session or extended play.
