Alien Zoo Tycoon

Welcome to Alien Zoo Tycoon, the idle tycoon game where your zoo floats in deep space. Build habitats on a drifting asteroid, fill them with strange and wonderful aliens, and watch astronaut visitors wander between the pens. Your zoo keeps earning even when you're not playing — come back to a hangar full of credits. COLLECT 50 ALIEN SPECIES Discover 25 alien species on Home Rock, then claim a second asteroid, Nova Isle, with 25 brand-new creatures of its own. Aquatic aliens swim, leap and splash around their own pools — and somewhere out there is the legendary Astral Dragon. UPGRADE YOUR ZOO Turn simple crate pens into fenced paddocks, stone enclosures and grand sanctuaries. Every upgrade changes how your zoo looks. Add food stands, gift shops and attractions to raise your star rating and attract more visitors. DESIGN YOUR LAYOUT Choose where every pen goes on your asteroid map. Long-press to move a pen, or drop it on another to swap them. HIRE KEEPERS Put zoo keepers in charge of your habitats to automate your income while you focus on growing your zoo. WARP TO NEW GALAXIES When you're ready, fire up the Warp Drive. Start fresh in a new galaxy with Dark Matter that permanently boosts your income and unlocks powerful perks. RIDE THE ZOO LINE Watch the maglev train glide between your asteroids, carrying visitors across the gap to explore.
