Yorg IO 3 is a multi-tower-defense game that focuses on a player building a base and maintaining a supply chain of ammunition to protect towers during a zombie apocalypse. Gameplay includes mine placement and building and management of factories. Players also unlock tower secrets.
When a player clicks or taps the "Play" button, a home screen load that displays various menu icons. Before playing in Singleplayer or Multiplayer mode, they should tap the gear at the bottom right corner to access the Settings menu to adjust graphics, language and game settings. On this screen, they should turn on the tutorial feature and keyboard shortcut notifications. They can also set alerts so that the game tells them the locations of zombies and if they're attempting to build in a location that has limited resources.
On the main screen, the player should familiarize themselves with other menus. By tapping "Skins & Store," they see goodies made available after they save enough in-game money known as "Coins." "Account" allows the player to create a name and account with an email address. "Leaderboard" displays a screen that shows all player rankings. "Achievements" takes them to a screen that shows in-game goals, including "secret" achievements. Players earn Coins when they reach achievements. Lastly, "Mods" leads to information about available modifications, such as increasing the size of maps or displaying the health of buildings. Keep in mind that some of these modifications reduce game functionality in other areas.
When the player is ready to begin, they click or tap "Singleplayer" or "Multiplayer." If they select "Singleplayer," then they're given access to the beginner Forest environment and Easy mode. The player must earn Coins to unlock additional maps and levels. If the player selects "Multiplayer," they can create a lobby and play against a friend in the "Solo" mode or with a friend against other friends or strangers in the "Duo" mode.
No matter the selection, the game isn't difficult to play. With the Tutorial turned on, the game walks the player through every step using onscreen popup boxes and arrows. Yorg IO 3 starts with a story about how all of humanity has been infected with a zombie virus. The player must open mines to gather resources, build factories to make new resources, defend towers against zombies and explore the map. To perform these tasks, they click or tap icons that represent items and drag and drop the items to locations on the map as directed by the tutorial.
The first goal is install a "Crystal Mine" to create resources. After the player places the mine, they're given the next task with onscreen hints. As the player proceeds with constructing their base, the top right corner of the screen displays their progress with mining and collecting crystals, stones and other resources. It also shows the number of earned Coins. If they need a closer or clearer view of the map, they can click the "-" or "+" symbols at the corner of a black box at the top right corner of the screen to zoom in and out.
