Final Fortress Idle Survival
Final Fortress: Idle Survival is an insanely addicting, base building, zombie apocalypse survival game where you must build and manage a zombie proof fortress in order to survive. Gas is now the currency and, as your fortress grows, your income of gas does as well! Use your currency to expand your fortress, hire managers and upgrade each floor! Kill the zombies as they near your fortress for extra currency and toolboxes that you can open only after building your 9th floor! Do you have what it takes to survive the zombie apocalypse and build the best zombie fortress?
