The game uses a real-time control system that lets you control your character and use different types of attacks. Just like what happens in other modern-day MMOs, you can automate movement, so what will really take up your time is the micromanagement of resources in your inventory and random crafting.
You can choose between three different characters, which you can also customize with different skills and weaponry. You also have endless options to change the characters' physical appearance, although many of them require in-app purchases. That said, they're really all just optional superficial changes.
As you advance in the game, you can unlock new game modes and extras, like the possibility to join guilds, to set up your own shelter, improve your whole setup to get more bonuses, or even send zombies to attack other players' shelters.
