Determined II

The Determined II badge is the ultimate test of survival longevity, requiring you to reach the 500-day mark for the first time. Doubling the demand of its predecessor, it sits at the maximum 5-star difficulty while paying out 8 diamonds, the same reward as Determined I despite being far harder, which makes it a pure prestige objective.

Surviving 500 days means running a near-perfect, fully self-sustaining camp for an extraordinarily long time. By this point the early-game systems must be on autopilot: a constant food surplus, a heavily defended campfire, and stockpiles deep enough to absorb a bad night without collapsing. A single careless death this late erases enormous progress, so risk management becomes everything.

The winning mindset is defense and routine over ambition. Lock down a fortified base, keep redundant food and healing supplies, and resist the urge to explore dangerous areas for marginal loot. Playing with reliable teammates who can revive you adds a crucial safety net for such a long haul. Because there is no shortcut, this badge ultimately rewards discipline and consistency more than any single skill, completing it stands among the proudest achievements a 99 Nights player can claim.
