Comments on Planet Defense: Space TD for Android

★★★★★ Vishal Chauhan · Jun 24, 2026

This game is the absolute king of tower defense games! Save your planet from aliens, set up turrets, and make upgrades. The waves get progressively harder, but the fun is packed. The graphics are spotless, and the controls are easy. Build your strategy, place the turrets in the right spots, and completely wreck the aliens. It runs offline too, making it perfect for passing time

★★★★☆ Noah Peng · May 30, 2026

I enjoy the gameplay, but it needs to be easier to earn coins. The biggest bottleneck to progressing in this game is the fact that you get so little coins per run that it takes 10+ runs to get one upgrade (obviously, so you spend money to buy coins). I normally do not mind slow progression systems like this, but the problem with this game is that you're going to be stuck failing the same level for DAYS while you collect coins. It gets stale after a while, which is a turn-off.

★☆☆☆☆ James Buell · Jun 23, 2026

Soon as you hit stage 9 and up you gotta pay lots of money to get anywhere or get stronger. Looks pretty but it's trash.

★☆☆☆☆ AnDy Shenk · Jun 21, 2026

Shield capacitors.!!! Where/how to use.!!! NOT Satellite Force Field. NOT Shield Designs... says to upgrade force shield which I assume is the planetary shield, but can not find where to use. Not in the chip/module screen, the missile upgrade screen. I must have over 200 & can buy them in the shop but Does not have a place to use. Tried emailing. Tried wiki & videos. Tried stupid AI. Besides the slow level progression & the Shield Capacitors.!! decent game. No customer service to speak of

★☆☆☆☆ Jordan Paschke · Jun 11, 2026

Incredibly low paywall for a poorly developed game. Blueprints are required to upgrade weapons, but three of the weapons stop earning blueprints after hitting level six. All weapons and the planetary mines do nothing for level seventeen waves, same with Binary Planet level 16. This game ONLY wants you to spend money to unlock things that won't even help you progress beyond level seventeen. NOT WORTH DOWNLOADING
