What's new

## Copper Lung 1.1.0

**Submarine**
- Oxygen tank (O2 on the strip): lasts about 8 minutes underwater, refills at the surface or dock; an alarm sounds at 75%, 50%, 25% and empty
- Crush depth: 60 blocks (80 with Reinforced Hull Plating) – stay below it and the hull starts to give
- Hull noises in the deep
- Sea chart (M): a paper chart of the sea floor, drawn by your sonar as you explore
- Upgrades rebalanced so a fully upgraded sub still has to respect the eels

**Blood Eels**
- Take five flashes to drive off; only overcharged flashes stop their approach
- Attack more often, carry charges through flashes, and fight back if chased
- Drops go straight to your inventory

**Contracts**
- New: Depth Sounding, Eel Deterrence, Wreck Documentation, Seabed Survey
- Wreck contracts always find a sunken submarine

**The infection**
- A Blood Eel jump scare at 80% and a visitation at 90%
- Terminal stage turns the skin blood-red, visible on every player

**Other**
- Whispers in the deep, and strange lights in some photos
- /copperlung commands for testing
- New logo, cracked glass on hull breaches, many fixes
