What Alien Invasion Tower Defense is
This is an action tower defense game from developer Guy Hazi, first released in November 2016. Aliens advance in waves and your job is to stop them by building weapons and objects in their way. You only get four build types, so the game leans on smart placement rather than a big shop of towers. Every level throws harder enemies at you, which keeps the pressure on right to the end.
Building and placing your defenses
You set your weapons and objects directly on the map. Where you put them is the whole game.
| Action | How it works |
|---|---|
| Build | Pick one of four weapons or objects |
| Place | Set it where aliens pass close and linger in range |
| Upgrade | Unlock upgrades on a placement as you progress |
| Hold the level | Stop the wave before any alien breaks through |
Your four build options
The game gives you a tight set of four weapons and objects to work with, so you cover early and late waves by mixing them rather than stacking one type.
| Build type | Role |
|---|---|
| Weapon 1 | Direct damage on aliens that pass by |
| Weapon 2 | A different range or angle of attack |
| Object 1 | Shapes or slows how enemies approach |
| Object 2 | A fourth option to fill gaps in your line |
Tips for clearing tougher waves
A few habits help once the aliens get harder.
- Place along the path so enemies stay in range as long as possible.
- Upgrade your best-placed weapons before adding new ones.
- Use all four build types instead of repeating one.
- Fix the section where aliens broke through before the next wave starts.
