About Alien Invasion Tower Defense
Alien Invasion Tower Defense is a 3D strategy game where you defend against waves of alien enemies by placing and upgrading towers, commanding heroes with unique abilities, and adapting your tactics to 15 different enemy types across campaign, endless, and PVP modes. The standout feature is the custom level builder that lets you create and share your own maps with the community, plus real-time multiplayer battles where you earn currency to send tougher enemies at your opponents.

Alien Invasion Tower Defense
Alien Invasion TD is a new strategy 3D game with an exciting new design, campaign mode, endless mode, players custom-built levels and PVP online multiplayer.
The aim is to defend against waves of approaching enemies by placing and upgrading your defense towers, recruiting units and using special attacks and boosts. You will be challenged to reconsider your tactics and use different towers and heroes to complete the mission. Each mission has three levels of difficulty and two special modes with player handicap.
Towers
Building and upgrading towers to attack enemies – each tower with its own unique advantages and upgrades – will enable you to overpower the waves of enemies.
The following towers are available:
- Tesla Tower - electricity bounce
- Cannon Tower - AOE
- Plasma Tower - freeze effect rate
- Soldier Tower - recruit soldiers
Each tower has nine different types of upgrades and improvements.
Heroes
There are a total of four heroes to unlock, each with its own unique skills which will aid you in different circumstances. At each level you can use up to two heroes. Different heroes are superior at different levels – select the right ones or you will face staggering defeat.
- Willy - fast speed and high damage, he can place mines to stop the alien swarm.
- Kristy - armed with her rocket launcher, she is able to inflict substantial AOE damage and has a special freeze missile.
- Thunder - equipped with a sniper rifle and a jetpack, he has a deadly long-range attack.
- Dave - high health and armor combined with a lethal shotgun and a grenade-launcher to block enemies.
Enemies
The aliens won't show you any mercy so you better watch out! There are 15 unique enemies with different traits which will make you reconsider your tactics at each level. The awesome stuff they can do includes teleporting, speed-boosting, sniping, freezing and destroying towers and more.

Online Multiplayer PVP
The game has a real-time multiplayer mode in which you need to both attack and defend.
You earn a special currency throughout the battle which can be used to send more enemies to your opponent when you see a hole in his defense.

What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
This tower defense game offers simple, budget-friendly gameplay that some find engaging and challenging later on, but most players criticize its slow early pacing, limited tower variety, and clunky mechanics like mandatory click-heavy tower upgrades and freezing effects that disrupt gameplay. The game suffers from feeling like a stripped-down mobile port with dated graphics and excessive grinding requirements, though a few players appreciate it as a cheap timewaster with decent late-game difficulty.
this game was fun until the idiotic freezing effect from certain mobs then it became a clicker and you cant upgrade your towers because you have to click on every tower 4 times to break the ice. also you cant choose targets with your towers decent for the price but annoying mechanics ruin it late in the game.4 found this helpful
A pretty standard tower defense with hero units. Heroes are pretty much mobile turrets that upgrade with a separate currency. Pretty simple graphics, no story, the UI is designed for mobile/touchscreen. Two out-of-battle currencies, diamonds and coins. Diamonds are used to permanently upgrade hero units while coins unlock upgrade tiers for towers (you spend in-battle currency to upgrade towers). Eventually (with my skill level) it got to the point where a lot of grinding was required to beat the level (I needed more diamonds/coins to upgrade stuff to not be overwhelmed by the waves). I did it for a little while but didn't really care enough to keep playing long after that point. Worth a look if you want a timewaster/grindy simple TD game. However, it's less polished and requires more grinding than other hero TDs (like Kingdom Rush or PixelJunk Monsters Ultimate). Other thoughts:[list] [*] Would be better if you play on a touchscreen. Seemingly no keyboard controls (not even esc for the pause menu). I would have liked to at least be able to scroll the map with WASD/arrow keys but you're forced to click and drag the map. I also found myself wanting to click and drag (box) to sele…2 found this helpful
https://youtu.be/NYYYZp7RbgE Out of the gate the action is far to slow to challenge players. The even slower drip of new upgrades and options don't provide motivation to invest in this game.1 found this helpful
Its a fun game but I have run into a snag where I cannot move around with my mouse, the game does not scroll in reponse to my mouse movements It is simple and fun and cheap, sorta like twiddling your thumbs, I highly recommmend1 found this helpful
This is just a crappy mobile game with only 4 tower types and dreadful graphics. It's bad even for a mobile TD, let alone compared to some free TD games you can play on PC (like Cursed Treasure).
After the first few levels, I thought this might turn out to be a cutsie, easy game - I was wrong! A lot of thought is needed. Great bang per buck game.
