After testing dozens of repositories and cracking forums, here are the three most stable and feature-rich scripts currently available. Note: Always use a temporary or alt account, as scripts violate Roblox ToS.
Many top-tier cruise ship scripts borrow from the "Inf Yield" admin library. This allows you to:
class Attraction
float baseIncome
int level
float interval
float growthFactor
float getIncome()
return baseIncome * level * Global.multiplier
float getUpgradeCost()
return baseCost * pow(growthFactor, level)
void collect()
Player.balance += getIncome()
void upgrade()
cost = getUpgradeCost()
if (Player.balance >= cost)
Player.balance -= cost
level += 1
