One of the biggest early-game decisions in Subnautica 2 is which vehicle to prioritize. The Seamoth is quick, nimble, and cheap. The Cyclops is massive, powerful, and... let's say "complicated." Let's break down exactly when to build each and why. Spoiler: you probably want both eventually, but here's how to decide which comes first.
Quick Summary
🏎️ Seamoth
The sports car of Subnautica 2. Fast, maneuverable, and perfect for quick trips.
- Best for: Speed, shallow-mid depth exploration
- Cost: Low
- Learning curve: Easy
🚢 Cyclops
The submarine base. Slow but powerful. Can carry vehicles and act as a mobile home.
- Best for: Deep exploration, carrying gear, mobile base
- Cost: High
- Learning curve: Steep
Speed Comparison
Look, the Seamoth isn't winning any races against actual fish, but compared to the Cyclops? It's like comparing a Ferrari to a school bus. The Seamoth will zip around the shallows and even mid-depths with ease. The Cyclops is more of a "set it and forget it" vehicle for long journeys.
Pro tip: Use the Seamoth as your "commuter vehicle" and the Cyclops as your "base on wheels" for extended expeditions. They complement each other perfectly!
Depth Rating
This is where things get interesting. The base Seamoth can handle depths up to 200m, but with hull upgrades, you can push that to 500m+ before it starts imploding. The Cyclops? Built like an absolute tank at 500m base depth, and it can go deeper with proper care.
Warning: Taking an unupgraded Seamoth below 200m is basically asking for a wet grave. Check your depth gauge!
Storage & Capacity
Here's where the Cyclops absolutely dominates. The Seamoth has limited inventory slots - enough for day trips but not much else. The Cyclops, on the other hand, can:
- Carry a fully equipped Prawn Suit in its docking bay
- Hold enough resources for multi-day expeditions
- Act as mobile storage (hello, base extension!)
- Accommodate multiple players in multiplayer mode
The Seamoth can't compete here. It's a scout vehicle, not a hauler.
Combat & Defense
Both vehicles can be equipped with defensive modules, but they serve different purposes:
Seamoth Defenses
- Torpedo bays (offensive)
- Hull reinforcement (damage resistance)
- Sonar module (threat detection)
Fast and evasive. Strike and scoot.
Cyclops Defenses
- Thermal torpedo bay
- Shield generator (energy shield)
- Sonar + decoy system
Heavy armor and energy shields. Face threats head-on.
Resource Cost Comparison
Seamoth Cost
- Titanium: 15
- Glass: 10
- Copper: 5
- Battery: 1
Total: Low investment
Cyclops Cost
- Titanium: 150+
- Glass: 60
- Lead: 40
- Copper: 60
- Lithium: 30
- And more...
Total: MAJOR investment
Building a Cyclops is a mid-to-late game project. Don't even think about it until you've got a solid resource gathering operation going.
Our Verdict
Build Order: Seamoth FIRST, Cyclops SECOND
Here's our recommendation based on dozens of playthroughs:
- Week 1: Build a Seamoth immediately. It's cheap, fast, and will revolutionize your exploration.
- Week 2-3: Upgrade your Seamoth with hull modules for deeper dives.
- Week 4+: Start gathering Cyclops materials. By this point, you'll have the resources and experience to handle it.
The Seamoth keeps you alive and mobile early game. The Cyclops becomes your endgame powerhouse once you're established.
