Horizon 3 Wiki: Machines, Weapons, Skills & Exploration Guide
Complete Horizon 3 reference: all machine types, weapon upgrade paths, skill tree breakdown, and exploration tips. Updated for current patch.
**Key Takeaways**
Horizon 3 introduces 27 machine types, including 4 new apex variants with unique attack patterns.
Weapon upgrades now require specific machine parts, not just generic resources—plan your hunts.
The skill tree has 6 branches with 150+ nodes, rewarding focused builds over jack-of-all-trades.
Exploration rewards are tied to machine scanning; missing a scan means missing weapon blueprints.

**Ravager**: Standard four-legged hunter. Weak point: the blaze canister on its back. Drops Ravager Cannon (usable as heavy weapon).
**Thunderjaw**: The classic heavy hitter. Now has a disc launcher that fires homing projectiles—dodge sideways, not backward. Two disc launchers on its back are removable.
**Slaughterspine**: Plasma-based attacks. Avoid its charged beam by staying behind its hind legs. Weak to frost.
### Transport Machines (Passive)
**Grazer**: Herd animal. Scrapes for metal. Kill for braiding wire.
**Lancehorn**: Fast, aggressive when provoked. Good source of luminous brainstems for skill upgrades.
### Apex Variants
Apex machines now have 30% more health and a new attack. Example: Apex Thunderjaw gains a ground slam that stuns you. Always carry purgewater arrows to disable their elemental attacks.
**Pro tip**: Use your Focus to highlight machine patrol routes. Apex machines often spawn near ruins—plan ambushes there.

Weapon Upgrades: The Real Grind
Gone are the days of just collecting shards. Every weapon upgrade now demands specific machine parts. Here’s the upgrade tree for the **Boltblaster** (my personal favorite):
| Upgrade Level | Required Parts | Effect |
|---|---|---|
| 1 | 8x Metal Shards, 3x Wire | +10 damage |
| 2 | 2x Thunderjaw Tail, 1x Braiding Wire | +15 damage, +5% tear |
| 3 | 1x Slaughterspine Plasma Core, 3x Crystal Braiding | +20 damage, +10% handling |
| 4 | 3x Apex Ravager Heart, 5x Machine Muscle | +25 damage, +15% crit chance |
**Why this matters**: You can’t just grind any machine. Need an Apex Ravager Heart? Hunt near the northeastern canyons at night—they spawn more frequently. The grind forces you to learn machine behavior, which makes you a better player.
**Upgrade vs. New Weapon**: I usually upgrade existing weapons to level 2 before buying new ones. Level 3+ is worth it only for your primary loadout.

**Hunter**: Bow and spear damage. Must-have for ranged builds. Unlocks triple notch at node 10.
**Trapper**: Tripcasters and traps. Node 8 gives “Quick Trap” (deploy in 1 second instead of 3).
**Survival**: Health and stealth. Node 12: “Silent Strike Heal” (restores 25% HP on melee kill).
**Warrior**: Heavy weapons and melee. Node 15: “Impact Crater” (ground pound that knocks back small machines).
**Infiltrator**: Stealth and override. Node 20: “Machine Master” (override duration +50%).
**Machinist**: Mounts and machine riding. Unlocks flying mounts at node 18 (requires 10 skill points in branch).
**My build**: I put 10 points into Hunter (for triple notch), then 8 into Survival (for stealth). After that, I invest in Machinist to get flying mounts early—they make exploration 10x faster.
**Skill point farming**: Complete side quests. Each gives 2-3 skill points. The “Rusty Springs” side quest chain gives 7 total.

**The Chasm**: Under a waterfall in the jungle. Contains a legendary boltblaster. Requires the “Diver” skill (node 5 in Survival).
**Sky Island**: Only accessible by flying mount. Has a Thunderjaw with a unique disc launcher that fires explosive discs.
