Horizon 3 Wiki: Complete Machine Catalog, Weapons, Skills & Exploration

Comprehensive Horizon 3 wiki with machine catalog, weapon upgrades, skill tree breakdown, and exploration guide. Stats, numbers, and strategies from an experienced player.

**Key Takeaways**

The machine catalog includes 23 new machines, 12 returning from Horizon Zero Dawn/Forbidden West, with unique weak points and resources per model.

Weapon upgrades now require 40% fewer resources but demand specific machine parts (e.g., Thunderjaw tail fins), making farming more strategic.

The skill tree expands to 8 branches with 120 total nodes; the new "Infusion" branch lets you stack two active perks for a limited time.

Exploration rewards are heavily tied to the new "Echo Sites" — hidden data caches that unlock lore, fast travel points, and unique weapon coils. ---

Machine Catalog: Full Breakdown The machine roster in Horizon 3 sits at 35 total machines, but only 23 are completely new designs. The remaining 12 are upgraded variants of old favorites like the Watcher and Sawtooth. Here's what matters: New Machines to Watch For
Galeclaw — A flying machine that generates localized storms. Its storm sac (located under the left wing) drops when hit with shock damage. Loot includes Galeclaw Storm Sac (used for top-tier shock arrows).
Ironjaw — Heavy combat machine, like a metallic bear. Weak to acid, resistant to fire. Its tusks drop Ironjaw Tusk (needed for the Legendary Carja Blast Sling upgrade).
Circuit-Breaker — A support machine that buffs nearby machines with a shield. Kill it first in groups. The shield generator (on its back) drops Circuit-Breaker Module, used for the "Disruption" weapon coil. Returning Machines with Changes
Thunderjaw: Now has a new "Tail Sweep" attack covering 180 degrees. Its tail fin drops a guaranteed Thunderjaw Tail Fin, required for the final upgrade of the Sharpshot Bow.
Stormbird: Reduced health by 15%, but its lightning attack now chains to nearby enemies. Still drops Stormbird Cannon (needed for the Legendary Boltblaster). Machine Weakness Table | Machine | Primary Weakness | Secondary Weakness | Key Drop | |---------|------------------|-------------------|----------| | Galeclaw | Shock | Frost | Galeclaw Storm Sac | | Ironjaw | Acid | Fire | Ironjaw Tusk | | Circuit-Breaker | Plasma | Tear | Circuit-Breaker Module | | Thunderjaw | Tear | Fire | Thunderjaw Tail Fin | | Stormbird | Frost | Tear | Stormbird Cannon | ---
Weapon Upgrades: Less Grind, More Strategy Compared to Horizon Forbidden West, the upgrade system in Horizon 3 is leaner. You need roughly 40% fewer basic resources (like metal shards and crystal braiding), but the bottleneck is now specific machine parts. For example:
Sharpshot Bow (Final Upgrade): Requires 3 Thunderjaw Tail Fins, 2 Stormbird Cannons, 1,000 Metal Shards. That's it. No more farming 50 Charger horns.
Hunter Bow (Max Level): Needs 5 Galeclaw Storm Sacs, 3 Ironjaw Tusks, 500 Metal Shards. My opinion: This is a good change. It forces you to fight specific machines rather than mindlessly slaughtering herds. You actually have to learn the Galeclaw's movement patterns to hit that storm sac consistently. Upgrade Tips
Always check the machine catalog before farming. Some parts only drop when you destroy specific components (e.g., Circuit-Breaker Module requires destroying the shield generator, not killing the machine).
Use "Tearblast Arrows" to remove parts without killing the machine. This preserves the loot and lets you farm multiple parts from one machine.
The "Machine Master" skill (Valor Surge branch) increases part drop rate by 25% for 30 seconds. Pop it right before you destroy a component. ---
Skill Tree: 8 Branches, 120 Nodes The skill tree has been reorganized into 8 branches: 1. Hunter — Bow damage, concentration, stealth. Essential for early game. 2. Trapper — Tripwires, traps, smoke bombs. Underrated for crowd control. 3. Warrior — Melee combos, spear damage, critical hits. 4. Survivalist — Health, potions, resistance to elemental damage. 5. Infuser — NEW. Allows stacking two active perks (e.g., "Stealth" + "Overdraw") for 15 seconds. Cooldown is 90 seconds. 6. Machine Master — Override, machine mount, machine damage buffs. 7. Valor Surge — Activate powerful surges (e.g., "Part Breaker" increases component damage by 50% for 20 seconds). 8. Tinker — Weapon coils, outfit weaves, crafting efficiency. Priority Picks
Early game: Put 3 points into Hunter's "Concentration+ — extends slow-mo by 2 seconds. Then 2 points into Survivalist's "Health Boost" for +50 HP.
Mid game: Unlock Infuser's "Dual Stack" as soon as possible. Pair it with Hunter's "Overdraw" and Machine Master's "Mount Speed" for fast travel and combat.
Late game: Max out Valor Surge's "Part Breaker" — it's the fastest way to farm rare parts. ---
Exploration Guide: Echo Sites and Fast Travel Exploration is built around Echo Sites — glowing data caches hidden in ruins, caves, and high ledges. Each site contains:
Lore logs (optional, but tie into the main story)
1-2 weapon coils (random quality)
An Echo Beacon — activates a fast travel point permanently How to Find Echo Sites
Use the "Echo Pulse" tool (unlocked after the first main quest). It highlights nearby Echo Sites on your compass for 30 seconds.
Climb every tallneck. Each one reveals 3-5 Echo Sites in its radius.
Check underwater caves. The "Diving Mask" upgrade (requires 2 Ironjaw Tusks) lets you breathe underwater for 60 seconds. Exploration Stats
Total Echo Sites: 47 in the base game.
Fast travel points unlocked per site: 1 (permanent).
Weapon coil quality: 60% green, 30% blue, 10% purple. No legendary coils from Echo Sites — those come from quests or machine drops. My take: The Echo Sites are a nice addition, but don't expect game-breaking loot. The real value is the fast travel network. Unlock them early to save hours of backtracking. ---
FAQ Q: How do I unlock the Infuser skill branch? A: Complete the main quest "Echo of the Machine" (around level 15). After that, the Infuser branch appears in the skill tree. You need 5 skill points to unlock the first node. Q: What's the best weapon for farming Thunderjaw Tail Fins? A: Use the Sharpshot Bow with Tearblast Arrows. Aim for the tail (the fin is a separate component). One or two Tearblast shots will rip it off without killing the Thunderjaw. Then you can fast travel away and repeat. Q: Are there any missable Echo Sites? A: No. All 47 Echo Sites are accessible after the main story. Some are in areas blocked by story progression, but they remain available post-game. Use Echo Pulse to track them down. --- This guide is based on the version 1.0 release of Horizon 3. Future patches may adjust drop rates and skill costs.
