1. Buff SDV storage by 100 (SDV is rarely used due to its slow speed, a small storage buff would make it more viable)
2. Add "Shark" quest/title for 100 underwater kills
3. Add rebreathers and diving goggles to rebel (we already have wetsuits)
4. Buff turtle spawn rate by 30-50% to make runs faster and less boring, reduce sell price accordingly
5. Buff strider storage by 10 (holds 2 more turtles)
6. Make watertight hull upgrade not useless for strider (increased speed in water)
