Comments on Space STG 3 for Android

★★★★★ 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.
★★★★★ 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
★★★★★ Ezra · Dec 22, 2025
Great way to pass time. What ever happened to online gameplay? Love this game, looking forward to space stg 4 if it ever comes. This game is very fun and surprisingly well-developed. The game is a good mix of challenging yet simple. Although, sometimes it's difficult to obtain resources for ship upgrades. other than that I have no complaints, fun game
★☆☆☆☆ 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.
★☆☆☆☆ Jim · May 24, 2026
Great game, bonus levels are ridiculous, game engine launches missiles without sounds like every other level as if it's cheating....and game engine can come up with bonus weapons it shouldn't have thus making bonus levels unbeatable
