The sequel to the real-time strategy classic Alien Tribe 2, which reached the Top 10 in more than 25 countries. Explore a distant galaxy. Colonize new worlds. Research ancient technologies. Connect entire star systems into a unique energy network. It all started with one unforgettable night: After escaping Maloc territory, the Fifo threw the biggest party in their history aboard their ark ship – and, for obvious reasons, didn't invite the autopilot. Big mistake. The autopilot, a hopelessly outdated shipboard AI that had served the Fifo faithfully for centuries, finally had enough. Before sunrise, it beamed the entire tribe onto an unknown planet in a distant galaxy. The Fifo woke up with no ship, no way home – and one legendary hangover. And things only got worse: The ruthless Maloc have picked up their trail again – presumably tipped off by the autopilot out of revenge. And the new galaxy is home to the Kytar: cute to look at, but anything but harmless. The autopilot has given the Fifo a nearly impossible task: Colonize every star system and connect them all into one energy network – then it will return. Provided they promise to invite it to the next party. Now it's up to you. EXPLORE A DISTANT GALAXY Send research ships into unknown star systems. Discover anomalies, investigate ancient wrecks, and uncover resource-rich asteroids. Every game takes place across newly generated star systems – no two are alike. BUILD YOUR ENERGY NETWORK Your energy network is at the heart of Alien Tribe 3. Connect solar power plants, planets, and defensive installations into a galactic power grid – the backbone of your entire infrastructure. If a connection breaks, everything downstream loses power. Plan carefully and defend every link. EXPAND YOUR EMPIRE Colonize planets, build mining stations, research centers, repair stations, and defensive installations. Secure resources and create an economy that can keep running even under constant pressure. RESEARCH AND ADAPT Expand your capabilities with a dynamic, card-based research system featuring around 25 technologies. Every decision comes at a cost: Will you focus on military strength, science, or your economy? Every game plays out differently. COMMAND YOUR FLEET Command harvesters, construction ships, research vessels, colony ships, and combat ships in real time. Each ship class has its own role. FACE THE MALOC Maloc attack waves strike from different directions and grow stronger over time. Build defense platforms, secure chokepoints, and decide when expansion matters more than defense. PREMIUM, OFFLINE, FAIR Buy once. Play forever. No ads. No in-app purchases. No pay-to-win. Fully playable offline – on a plane, on a train, or from your couch. FEATURES • Real-time strategy with 4X elements: exploration, expansion, research, and combat • A galactic energy network at the heart of every strategic decision • Card-based research system with around 25 technologies • Procedurally generated star systems – every game is different • More than 15 buildable stations and ships for economy, research, and defense • Specialized ship classes with distinct roles • Premium game: fully offline, no ads, no in-app purchases • Optimized for iPhone and iPad The galaxy is waiting.
