BetterSewerKeys
BetterSewerKeys transforms the sewer key system from a single-use master key into a strategic per-entrance unlocking system. Instead of one key unlocking all sewer entrances, each entrance now requires its own key.
What Changed?
Vanilla Behavior
- Using a single sewer key unlocks all sewer entrances globally
- One key = access to the entire sewer network
With BetterSewerKeys
- Each sewer entrance requires its own key
- Keys unlock only one entrance at a time
- You must strategically choose which entrances to unlock
- Multiple methods to obtain keys: buying, pickpocketing, or finding them in the world
Features
Per-Entrance Unlocking
- Each sewer entrance has its own unique key
- Keys are consumed when used and unlock only the specific entrance you interact with
- Once an entrance is unlocked, it remains open permanently (no key needed for future access)
Multiple Key Acquisition Methods
1. Buying from Jen
- Purchase keys from Jen (NPC) if you have sufficient relationship status
- Each purchase gives you a key for the next locked entrance
- Keys can be bought sequentially until all entrances are unlocked
2. Pickpocketing
- Random NPCs are assigned as key possessors for different entrances
- Use your pickpocketing skills to steal keys from these NPCs
3. World Pickups
- Random sewer keys spawn at various locations throughout the world
- Keys relocate to new positions each day
- The pickup system continues until all entrances are unlocked
Save System Integration
- Full integration with the game's save system via S1API
- Unlock states persist across saves
- Automatic migration from vanilla saves (if you had previously unlocked sewers, all entrances will be unlocked in the migrated save)
- Key distribution and pickup locations are tracked per save
Installation
- Ensure you have MelonLoader installed for Schedule I
- Place the
BetterSewerKeys_Il2cpp.dllorBetterSewerKeys_Mono.dllfile in yourMods/folder - Launch the game - the mod will automatically initialize
Requirements
- Schedule I (ScheduleOne)
- MelonLoader
- S1API (for save system integration)
Notes
- The mod uses the same sewer key item as vanilla - the difference is how they're consumed (one entrance vs. all)
- Once an entrance is unlocked, you can access it freely without needing another key
- All entrances must be unlocked individually - there's no "master key" anymore
- The random world key pickup will continue spawning until all entrances are unlocked
