Alien Invasion Tower DefenseDefend your base from waves of aliens: place four weapon types along a fixed path and upgrade them as the invasion gets tougher round by round.
Alien Invasion Tower Defense
Alien Invasion Tower Defense is a fast, tactical browser strategy game: aliens push down a set path toward your base, and you have to stop them before they get through. Rounds ramp up quickly, so the challenge is less about grinding and more about reading each wave and reacting to it before it’s already at your door.
You only get four kinds of weapons and defensive structures to work with, so where you build matters more than how much you build. Killing aliens earns resources, which you feed back into upgrading the defenses already on the field rather than constantly adding new ones — a session is a steady loop of placing early, watching what the next wave throws at you, and upgrading to match it.
Controls
Click an open spot along the path to build one of the four defenses, and click an existing one to upgrade it. On a touchscreen, tapping does the same job.
It’s a tight, session-sized pick for anyone who likes classic path-based tower defense without a huge tech tree to manage — built by developer Guy Hazi.
