The Protect the House from Monsters perks system is the backbone of progression in the game. By unlocking and upgrading perks across four main trees—Stamina & Survival, Weapon, Turret, and Resistance—players can build stronger characters, defend their base more effectively, and survive longer against waves of monsters and bosses. This guide breaks down every perk tree, highlights the best upgrades, and provides practical tips for both early-game farming and late-game defense.
Overview of the Perk System in Protect the House from Monsters
Perks are special upgrades that enhance your character’s abilities or boost turret performance. They are divided into four perk trees:
Stamina & Survival (blue + purple) – improves mobility, stamina, and survivability
Weapon (red) – focuses on damage, reloads, and critical attacks
Turret (green) – enhances base defenses with stronger and more reliable turrets
Resistance (mixed blue + purple) – adds durability, vision, and regeneration for boss fights
Each tree requires significant investment, so choosing the right path at the right time is critical for efficient progress.
Stamina & Survival Perks
Key Perks: Endurance, Sprinter, Vitality, Skybound
Endurance grants +10% stamina, helping with longer sprints.
Sprinter boosts sprint speed by +10%, useful for farming and dodging mobs.
Vitality adds +50% HP regeneration, keeping you alive during heavy fights.
Skybound unlocks double jump without consuming stamina. It speeds up air movement and makes you harder to hit, costing around $36,000.
Other options like Medic, Flashlight, and Helmet & Armor add to overall survivability.
Total Cost and Best Early Picks
Unlocking the full tree costs around $50,000. For beginners, prioritize Endurance, Sprinter, and Skybound to boost farming efficiency and avoid early deaths.
Weapon Perks
Best Damage Perks: Piercer and Strike
Piercer lets bullets penetrate enemies, hitting two targets at once. It’s one of the strongest farming perks and costs $60,000.
Strike increases weapon damage by +20% for both melee and guns, making it a reliable choice for overall DPS.
Critical and Efficiency Options
Critical doubles the damage on every fourth shot (with a bug that sometimes triggers more often). Cost: $30,000.
Efficiency and Quickdraw improve reload speed and fire rate, while Hitman reduces melee stamina usage.
For an early boost, Piercer is the most valuable, followed by Strike for raw damage.
Turret Perks
Engineer Upgrades
Engineer I–IV gradually increase the number of turrets you can place, setting the foundation for a strong defense.
Lock On and Overclock
Lock On ensures inaccurate turrets like Pulsar or Destroyer always hit, making it a must-have upgrade at $60,000.
Overclock I & II raise turret fire rate by 20%, drastically improving DPS.
Annihilator and Clone
Annihilator boosts Destroyer turret damage from 73 to 101, costing $66,000.
Clone allows deploying two of the same turret, such as dual Destroyers. Although it costs $200,000, it’s one of the most powerful late-game perks.
Must-have turret perks are Lock On for consistency and Clone for long-term scaling.
Resistance Perks
Vitality and Medic for Survival
Both perks keep your character alive through regeneration and healing, especially useful during boss phases.
Armor and Sight for Boss Fights
Helmet & Armor add extra protection.
Sight improves visibility in dark areas, making it easier to track enemies at night.
Combining regeneration with armor makes your character durable enough to withstand one-shot boss attacks.
Best Upgrade Order for Beginners
Start with Stamina & Survival: take Endurance, Sprinter, and Skybound first.
Move to Weapon: unlock Piercer early for farming efficiency.
Transition to Turret: prioritize Lock On, then save for Clone as a long-term goal.
Pick from Resistance when facing tough bosses, especially Vitality and Medic.
Recommended Perk Combinations
Stamina + Skybound: unmatched mobility for farming and survival.
Piercer + Strike: maximizes DPS and crowd control.
Lock On + Clone: turns your base into an unstoppable fortress.
Resistance perks: essential when preparing for boss encounters.
Tips for Farming and Surviving Boss Attacks
Unlock Skybound early to speed up farming and dodge attacks.
Use Piercer for efficient crowd clearing during coin runs.
Invest in Lock On to ensure your turrets consistently hit, especially with Destroyers.
Pair Vitality, Medic, and Armor to increase survival odds against late-game bosses.
Always prioritize perks based on your immediate needs: farming perks for early progress, turret perks for mid-game defense, and resistance perks for late-game survival.
