Stamina management in GTFO plays a critical role in determining how effectively you can move, fight, and survive the complex. From sprinting speed to melee charge times, your stamina directly impacts your performance. In this comprehensive guide, we’ll explore how the stamina and heart rate systems work, break down the mechanics in detail, and provide tips for managing stamina effectively during missions.

How the Heart Rate Monitor Works

The heart rate monitor in GTFO displays a range from 60 to 180 BPM, scaling directly with your remaining stamina:

• 60 BPM: Indicates 100% stamina.
• 180 BPM: Indicates 0% stamina.

Stamina Caps in Different States

• In Combat: Maximum stamina is capped at 75%, which means your BPM cannot drop below 90.
• Out of Combat: Stamina cannot drop below 40%, capping the maximum BPM at 132.

Combat Definition:

• You are considered “in combat” if enemies are awake or if there are active alarms, even if all enemies are currently dead.

Actions That Consume Stamina

Stamina affects three main actions:

1. Sprinting Speed: Reduced as stamina decreases.
2. Melee Charge Speed: Slows down when stamina is low.
3. Recovery After Melee Shove: Becomes longer with less stamina.

Actions That Drain Stamina

• Sprinting: Consumes 1.666% (2 BPM) in combat, 0.666% (0.8 BPM) out of combat.
• Jumping: Uses 5% stamina (6 BPM) regardless of combat state.
• Charged Melee and Shoves:
  • Hammer/Spear: 5% (6 BPM) per full charge.
  • Bat: 2.5% (3 BPM) per charge.
  • Knife: No stamina cost.

Stamina Recovery Rates

Stamina begins to regenerate 2.5 seconds after the last action that consumed it.

• In Combat: 15% (18 BPM) per second.
• Out of Combat: 25% (30 BPM) per second.

Tip: To fully recover to 75% stamina in combat, wait approximately 5.5 seconds.

Speed Reduction Based on Stamina

The default player speed is 6 units per second, which can drop to 4 units per second based on stamina loss:

• 0% Stamina: 6 units/second.
• 30% Stamina (144 BPM): Midpoint, speed reduction becomes more noticeable.
• 0% Stamina (180 BPM): 4 units/second.

Calculating BPM Based on Stamina

Use this formula:

• BPM = (Percent of Stamina Lost x 1.2) + 60
  • Example: At 60% stamina, you have lost 40%. Thus, BPM = (40 x 1.2) + 60 = 108 BPM.

Pro Tips for Managing Stamina

1. Sliding:
   • No longer increases speed but conserves stamina during sprints.
2. Avoid 30% Stamina Threshold:
   • If you drop below 144 BPM, speed and action penalties become severe.
   • Wait 5.5 seconds to recover if possible.
3. Combat Stamina Management:
   • Limit charged melee attacks to emergencies only.
   • Sprint conservatively to avoid burnout during extended fights.

Conclusion

Effective stamina management in GTFO requires a balance of movement, attack timing, and strategic pauses to recover. By understanding the mechanics of the heart rate monitor and stamina usage, you can optimize your actions to maintain speed and combat readiness.

Whether you’re a new player or aiming to master the complex, these tips should help you make the most of your stamina and heart rate management. Good luck!
