YORG.io is a tower of defense game like no other. Your goal is to defend your base at night from zombie attacks. Using a string a of supply chains, you must create towers that provide crystals and iron to build both defensive and offensive towers. You can play with your friends to see who builds the better base. YORG.io is a strategy game that requires a connection between its towers in order to provide goods to each other. In the beginning, you must focus on building crystal mines because crystals are your form of currency in the game. Use crystals to purchase buildings and upgrade them. From there, you can form a connection to create iron to use to create cannons and other defensive towers. If you’ve never played before, make sure to select the tutorial which gives a detailed description on how to play the game and use its tools to your benefit. The zombies only attack at night, so take the day to build up your defense. You have a mini-map in the corner to help you see where the zombies will be coming from. On the upper-right hand, you’ll see a scoreboard to see how well your friends are doing. On top of defending your base, Yorg.io gives you the chance to beat out other opponents that have joined in on the same server. Game Instructions: Use your mouse to place the towers on the map. Press shift to upgrade several towers at the same time.
