Better Submarine Upgrades - 更好的潜艇升级

Better Submarine Upgrades v1.1.0

Your submarine is so much more than this.

Tired of too few vanilla upgrades? Vanilla submarine upgrades are scarce, and every run feels the same—max hull, finish reactor, max turrets, and then nothing. Same routine, different submarine, same routine. This mod exists to break that cycle.

3 Submarine Types, 3 Completely Different Growth Paths

Attack, Transport, and Scout are no longer just name differences—their upgrade paths are completely different:

• Attack: Lower turret power consumption, faster turning, higher fire rate, more capacitor, and an exclusive [Pulse Laser Overload] upgrade. A pure firepower projection machine.
• Transport: Extremely thick hull, doubled pump efficiency, extremely fast repair, and extreme fuel efficiency. Makes survival a source of confidence.
• Scout: Strong engine thrust, extremely wide sonar range, very low noise, and long-lasting batteries. Detect the enemy first, retreat first.

Every level-up feels like a qualitative change, not just numbers going up.

40 Upgrades Covering Every Corner of the Submarine

From hull reinforcement, fabrication speed, and turret components, to reactor power, electrical systems, junction box fireproofing, noise reduction, and even independent door reinforcement—every detail can be upgraded. All upgrades have independent Tier unlock curves, gradually opening as the campaign progresses—you won't be invincible from the start, and every station visit brings new surprises.

Enemy Synchronization, Dynamic Gameplay

• Enemy Upgrade Sync (Lua): Your enemies no longer stagnate. Upgrades you purchase at stations are synced to enemy submarines (with different bonuses by category), so enemies grow stronger as you do, always bringing a challenge.
• AI Sight Link (Lua, affects both sides): Your AI crew's sight expands with your periscope upgrades, improving team coordination. But correspondingly, enemy AI sight also increases, making them harder to bypass with stealth and greatly deepening tactical gameplay.
• Plant & Mineral Scanning (Lua): The mineral scanner can now detect not only ore veins but also wild plant locations, so you no longer have to search blindly.

Global Sync Toggle (Experimental)

This mod supports manually toggling enemy upgrade sync via console commands, for testing or difficulty adjustment:

• bsusync — toggle state
• bsusync on — enable sync
• bsusync off — disable sync

Enabled by default.

Recommended Combination

• Recommended to use with Enhanced Pirates and Faction Bounty - Reconstructed 增强海盗与派系清剿_重构版 (optional, just a recommended combo)—the two work well together, letting your submarine upgrades be tested against smarter enemies.

More Recommendations

If you want to upgrade your submarine more comprehensively in other aspects, I recommend my other mod:

BaroCraftable Remake - Submarine Overhaul

Details Make Immersion

• A highly textured "tiered material system": hull reinforcement levels 1-2 use aluminum, while mid-to-late upgrades require titanium-aluminum alloy and even physicorium, fully immersing you in the world.
• Multi-dimensional defensive upgrades such as doors, blast resistance, fireproof coating, and overload protection make "survival" a tactical dimension that requires thought.
• Added a new oxygen generator category (not present in vanilla), supporting more specific life support needs.

Compatibility & Stability

• Joining mid-campaign with this mod inherits vanilla levels, but since vanilla per-level stats differ, stat caps may be higher or lower than this mod's.
• Fully standalone, no dependency on any vanilla override mods.
• Full Simplified Chinese + English support.
• Compatible with game version 1.13.4.0 (v1.1.0), tested.
