About this game

Star Marines: War Invasion

Warning sirens blare. Hostile contacts detected! The enemy swarm is on approach! Get ready, Commander! On this distant outpost, you are the last line of defense for your vital Star Marine base. This isn't just a mission; it's an endless war against relentless alien swarms!

Dive into the intense action of this strategic idle tower defense TD experience. Your mission is clear: defend against unstoppable waves of diverse and terrifying enemies. Confront swarms of metallic beetles, buzzing drones, horrifying giant spiders, and other monstrous alien entities. Each enemy force is determined to breach your perimeter and overrun your stronghold.

But you are not alone! Command your elite Star Marine force, hardened veterans equipped with advanced weaponry and cutting-edge tech. Deploy your force strategically, positioning your units and defensive turrets to create an impenetrable defense strategy. Your Star Marines are the key to holding the line – they man the heavy weapons, build the fortifications, and stand their ground against the alien tide!

This is where the idle advantage kicks in. The battle for survival never truly stops. Even when you're offline, your dedicated Star Marine force continues the fight, holding back waves of xenos and gathering vital salvage and resources. Jump back in to reinforce your force, research powerful tech upgrades, unlock new units, and strengthen every aspect of your base defense.
This is your duty: a continuous fight to refine your strategy and push back the alien threat. Enhance your Star Marine force, customize their loadouts, and build the ultimate base defense against the encroaching swarm. The fight for survival is brutal, but victory earns crucial salvage needed to stand against the ever-increasing enemy force. Upgrade your fortress!

Are you ready to lead your elite Star Marine force into the heart of the war against the alien enemy force? Can your strategy hold against the endless waves of beetles, drones, spiders, and other monsters? Download Star Marines: War Invasion now and deploy your force in the ultimate TD battle! Your base's survival depends on the courage of your Marines and the strength of your defense!

great game, really. 5 stars easy..... except for the game restarting after watching an Ad. half way through the level and you watch an Ad, game switches over to Google play and boom, forces a game restart. and there is no continue option at all. at first I thought it to be a rare event. but sadly no. it's truly a Russian roulette.

Very bland and boring game. After completing first level, you basicaly saw everything what this game can offer. Phase is slow. Every unit has only few upgrades and they are unimpresive. You can unlock some, but it does not make the game more interesting. Animation is lacking. +1 star for good music and for not forcing ads. But it is a shame that music does not match the phase of the game itself.

After update game fails to load around 78% and goes to black screen. After uninstall reinstall game fails at third query asking for gameplay profile 53/54% and goes to home screen. Since G&G:TD loads fine which seems to be a reskin with the same similar load points and design it is disappointing when one works and the other doesn't. Disappointed as before it was ..."so far so good we'll have to see how the game progresses after level two."
