Knock Knock: Room Defense – How to Master Stage 67 Soul Swapped

Stage 67 in Knock Knock: Room Defense serves as a significant hurdle for players due to the "Soul Swapped" mechanic. This stage introduces increased pressure on your room's defenses, requiring a shift in your standard resource management and door reinforcement strategy to survive the onslaught.

Understanding the Soul Swapped Mechanic

In Stage 67, the ghosts become significantly more persistent, and the "Soul Swapped" condition increases the frequency of damage to your door. Unlike earlier stages where you might be able to afford a slower build-up, this level demands an immediate focus on structural integrity and gold efficiency.

Core Survival Strategies for Stage 67

1. Prioritize Door Reinforcement Early

The most common cause of failure in Stage 67 is neglecting the door's HP. Because the ghost intensity ramps up quickly, you cannot rely solely on passive income.

Early Game: Focus your initial gold generation entirely on bed upgrades to maximize income.
Mid-Game: As soon as you hear the first knock, divert your remaining gold into reinforcing the door. Do not wait until the door is flashing red to start your upgrades.

2. Strategic Placement of Defensive Turrets

Since the ghosts in this stage are particularly aggressive, you need to ensure your defensive turrets are positioned to provide maximum coverage.

Spread your turrets: Avoid clustering all items in one area. By spreading them out, you ensure that even if one turret is temporarily disabled or bypassed, you have secondary fire covering your entrance.
Upgrade priority: Focus on one high-damage turret before building multiple low-level ones. A single maxed-out turret is often more effective than three level-one turrets during the Soul Swapped phase.

3. Resource Management Table

Use this priority list to allocate your gold during the heat of the match:

Priority Level	Item Category	Action
High	Bed	Upgrade immediately to increase gold flow.
High	Door	Reinforce if your HP drops below 70%.
Medium	Turret	Place at least two basic turrets early.
Low	Tech/Utility	Only purchase after stabilizing door and bed.

Tips for Surviving the Soul Swapped Waves

Don't Panic on Knocking: The knocking sound creates artificial urgency. Keep your rhythm consistent. If you react too quickly and dump all your gold into a minor door repair when it wasn't necessary, you might stall your bed upgrade progress.
Monitor the Ghost Progress Bar: Watch the intensity bar at the top of the screen. When it begins to fill rapidly, stop all non-essential building and pour everything into your door’s durability.
Persistence: If you fail, evaluate which resource was lacking. If you ran out of gold, focus more on your bed; if your door broke too early, focus on your defensive turret placement.

By balancing your income growth with reactive door maintenance, you can overcome the unique challenges of Stage 67 and move forward in Knock Knock: Room Defense.
