Comments on Alien Shooter TD for Android

★★★★★ Sultana Arju · Jan 17, 2026

Very fun game I like it, I love tower defense games

★★★★☆ Mark Billy · Apr 19, 2025

This game is really cool. It just needs a bit of rebalancing for resources and some extremely powerful aliens early ame is just a tad bit too hard to bring down. You run out of ammo fighting with no resources to keep fighting. Increase the resources per alien killed and probably power up some weapons as it does nothing to some aliens that come in droves. That will fix the game for better fun. It will also balance the warfare between human and aliens.

★★★★★ Christian · Dec 22, 2025

Overall great tower defense game, maybe add some almanac about soldiers and aliens that can be read outside of combat.

★★★★★ M DEY · May 28, 2025

The alien shooter TD game is very cool in childhood and now it is amazing. Huge crowds of alien and troops new types of guns. The story line of game is kind of thing. But I not fully satisfied of game level up skill only in level 4 it takes time 45 min, 1 hour like this it takes a long time for training the game should not take a long time!!! By the way the graphic is clear and so many amazing chest... and I like TD (tower diffence) game. Sigma company should fix those problems. Coolest game...

It's impossible to pass lvl 15, been stuck at that level and all hard lvls before that for a month...

★★☆☆☆ Juan Ramirez · Jan 16, 2025

Just too many things going on and not enough explanation of how to take advantage of all of them. No explanation of how to utilize the objects and options that are available. Nice graphics and it looks like they've created a good game, but really just impossible to understand what's going on. Uninstalled. Sorry guys - it really does look like a nice game you've created, just unplayable.

★☆☆☆☆ Adnan Elbzazy · Jun 1, 2025

It takes 14 hours to train at which time we can not use the solder. Make it so we can play with troops even when training them.
