About
Download 99Day Survival Guide Free for PC (Windows). Lock, load, and band together in this frantic, fast-paced cooperative zombie survival action shooter. Dropped straight into the epicenter of a relentless undead outbreak, you and your squad must fight tooth and nail across 99 escalating days of infected onslaughts to secure an extraction route and escape alive.
Cut down waves of mutated zombies using a diverse arsenal of firearms, melee weapons, and tactical gear. As you clear hordes and survive each grueling wave, draft randomized power-ups and experimental mutations to forge devastating character builds and cross-team combat synergies. Coordinate defensive positions, revive fallen teammates under fire, adapt to unpredictable boss mutations, and push forward together until the final rescue chopper touches down.
