Alien Invasion Tower Defense — Play Free Online

Jump & Platform

Play Alien Invasion Tower Defense free in your browser: a strategy game where you aim, place and defend against waves of invaders. No download needed.

Alien Invasion Tower Defense is a browser strategy game built around a familiar idea: something hostile is coming, and you stop it by deciding what to place and where. The catalogue files it under Jump & Platform, but the title tells you what a session looks like. It is a tower defense game, closer in spirit to Bloons Tower Defense 2 than to the climbing and bouncing games it sits beside.

That makes it a change of pace for anyone who came to the site for Doodle Jump. Instead of reacting in fractions of a second, you get a calmer, more planned kind of play. You watch what the invaders do, think about where your defences should go, and adjust. It loads in the browser with nothing to install.

How to play

The game lists these controls: use the arrow keys or WASD to move, and the mouse to aim and select. On a phone or tablet, tap and swipe instead. The mouse handles choosing and aiming, while the keys handle movement, so the two work together rather than being alternatives.

Start with the first level and use it to learn the interface before worrying about a high score. Pay attention to how the invaders approach, because their route decides where your defences are most useful.

Tips

Take the opening level slowly. Spend it learning what each control does and how the enemies move.
Use the fullscreen button under the game for a bigger view, which helps when you are aiming with the mouse.
If the game stalls, reload the page. It restarts cleanly.
