How to Play Office Knight 3D: Castle Defense

The mission is brutal. Defend the castle through endless waves of monsters. Each night gets harder. Kill enemies. Collect coins. Buy upgrades. Level up to heal and boost your stats. Survive until morning. That's it.

Combat & Movement

Move with WASD. Attack with LEFT MOUSE BUTTON. Space to jump over enemies. Left Shift sprints—use it to kite tough mobs or dodge swarms. Q swaps weapons mid-fight. Position matters. Enemies spawn in waves, so rotate around the castle walls to avoid getting surrounded.

Progression & Economy

Earn experience per kill. Level up restores health and grants permanent damage/stamina boosts. Coins drop from corpses. Walk to the shop. Press E to enter. Decision time: save for powerful weapons or buy quick health/speed upgrades. Dynamic difficulty means each wave brings more enemies with buffed stats. Spending smart is survival.

Arsenal & Strategy

Start with a club. Upgrade to the Hammer—unleashes area lightning strikes on crowds. Save for the Golden Sword—engulfs you in flames for bonus burn damage. Swap weapons with Q based on enemy type. Swarms? Hammer. Tanks? Golden Sword. Rush speed upgrades early. Kiting is life. Don't tank hits—dodge, sprint, strike.
