Determined I

The Determined I badge is an endurance milestone that asks you to reach the 250-day mark for the first time. Surviving that deep into a run is no small feat, which is why it carries a demanding 4-star difficulty, though the 8-diamond reward makes the long haul worthwhile.

Reaching day 250 is far beyond the standard 99-night arc, so it tests your ability to run a sustainable, self-sufficient camp rather than just surviving early raids. Food production, a defended campfire, and reliable healing all matter more the longer you push. Each day the threats escalate, so a camp that snowballs resources is what keeps you alive late.

The smart strategy is to invest heavily in food and defense infrastructure early so the mid-game runs itself, then play cautiously rather than chasing risky loot. Keeping a teammate or two alive shares the survival burden and the workload of fending off night attacks. Avoid unnecessary fights, keep everyone fed, and treat every night as a checkpoint. It is largely a patience-and-stability badge, but clearing it also sets you up perfectly for its harder sequel, Determined II at day 500.
