CastleMiner Z (Z is for Zombies) is a Indie Game for Xbox 360. It is the sequel to the game CastleMiner and each can be purchased for 80 MP (equivalent to $1), 240 MP originally. The difference between the two games is that this game has weapons, which you use to kill zombies, skeletons, and dragons, while gathering materials to build structures or craft new items.

There are a total of five game modes: Endurance, Survival, Free Build, Dragon Endurance, and Creative.

Endurance

Endurance's objective is to get as far in the world as you can while fighting enemies. Building shelter isn't the objective of the game, but is advised, as fighting enemies at night isn't an easy task. Killing the undead dragon unlocks the game mode Dragon Endurance. Dying online will make the player wait twenty seconds before they can respawn. This mode is the only mode available in the trial.

Survival

Survival's objective is to find resources, build a shelter and fight enemies. Building a shelter immediately is key to survival, since the night is when the horde of zombies come. Fighting enemies at night is not easy, especially on hard difficulty. It is recommended that the first rare resources you come across (except for Iron and Diamonds) should be used for your shelter's exterior, because dragons can destroy rock on hard difficulty. Don't run around at night unless you have some weapons, like Diamond weapons, or Bloodstone weapons.

There is also a new Hardcore mode in Survival. In hardcore, you cannot teleport. Also, when you die, you lose all your items and get the default items you start out with.

Free Build

Free Build is a game mode that lets you build and craft what you want without the undead bothering you. You can save your world and take it on survival mode at the Main Menu after you selected either Online or Offline play.
Dragon Endurance

Dragon Endurance's objective is to fight wave after wave of dragons, going up in difficulty as you progress. Building weapons is your priority, as killing a dragon with the default pistol is nearly impossible.

Creative

This mode is has Unlimited Resources and they can also decide to have enemies in their game or not but it can only be played after you have purchased the promo code from the First Castleminer Game (can be found on the bottom of the screen in the main menu).

Due to the addition of enemy A.I., CastleMiner Z has significantly less block types and can only support up to four players online as opposed to 16 player support in CastleMiner.
