About Castle Must Be Mine

Castle Must Be Mine immerses players in a VR tower‑defense experience where you construct and upgrade towers to protect a castle from invading monsters. By directing a hero, using special skills, and managing resources earned from defeated foes, you shape each battle’s outcome.

The game offers a variety of environments—forests, deserts, and ice fields—and supports cooperative play between two heroes on endless maps. Controllers let you launch fireballs, tornadoes, ice balls, and other attacks, while a world leaderboard tracks scores after each level.

01 / THE GUIDE

Building and Upgrading Towers

Players place defense towers on designated building points, then upgrade them using money earned from enemy kills. Strategic placement influences how effectively enemies are stopped. Upgrades improve tower performance, which helps manage larger waves of monsters.

  • Consider spacing towers to cover overlapping enemy paths.
  • Upgrade towers after a few kills to maximize early earnings.

02 / THE GUIDE

Commanding the Hero

The hero can be directed to attack enemies, gaining experience points that lead to level‑ups. Higher levels enhance the hero’s combat effectiveness. Using the hero’s special skills in conjunction with towers creates a layered defense against both land and flying monsters.

  • Use the hero to target fast‑moving flyers that towers may miss.
  • Balance hero attacks with tower fire to keep enemy numbers low.

Monsters and Enemy Types

The game features over 30 distinct monsters, including both land‑based and flying varieties. Each type may require different defensive tactics. Understanding monster behavior helps decide which towers or hero abilities to prioritize during a wave.

  • Prioritize defenses against flying monsters early when they appear.
  • Observe monster patterns to adjust tower placement on the fly.

04 / THE GUIDE

Map Environments

Players can battle across 5 forest‑style maps, 4 desert‑style maps, and 3 ice‑field maps. Each environment presents unique visual themes and layout challenges. Endless maps also support cooperation between two heroes, extending gameplay beyond single‑player scenarios.

  • Try different map styles to discover which tower layouts work best.
  • Co‑op mode can ease tougher waves by sharing hero abilities.

05 / THE GUIDE

Controller‑Based Attacks

Using tracked controllers, players can throw fireballs, tornadoes, ice balls, and boulders from the castle wall to damage or block enemies. Additional actions include firing a cannon and casting spike traps. These gestures add a physical layer to combat, letting you target specific enemy groups directly.

  • Aim throws at clustered enemies for maximum impact.
  • Combine cannon fire with spike traps to create choke points.
