Comments on Space STG 3 for Android

★★★★★ James Oss · Nov 18, 2025
This game is awesome, so long I have come across planets very realistic if this was real. Hoping the developers are just getting started
★★★★★ Benjamin Makengo · Mar 12, 2026
​Really appreciate the effort put into Space STG 3. The improvements over the previous games are fantastic. Thanks for the great updates!
★★★★★ Andrew Saunders · Sep 26, 2025
Solid old game that I have played for over a decade and stil enjoy. Lost count how many times I have played through all the missions over the years.
★★★★★ J Landry · Apr 3, 2026
I keep coming back to this game, and It's still very hard to our down. The strategic map is well done, missions feel challenging without being too hard at first. The tactical battle layer is where this really shines. Turn based, and tech advances feel like they make a difference. The ship types feel different, learning what a class does well and capitalizing on that makes a large difference. I'd recommend this to anyone. You have option of watching videos but fantastic free to play.
★★☆☆☆ Sarel Greeff · Sep 6, 2025
It's a good game lots of good stuff inside if you like space games this is for you.
★☆☆☆☆ V-T L · Mar 30, 2026
Horrible garbage. Tutorial is 60 seconds. Battles are ridiculous. 1/5 of screen is blocked by ad that doesn't go away. I bet there are way better space strategy games out there.
★★☆☆☆ Henry Songkit · Jun 3, 2025
Need a new update, bug the app quit automatically.
