Decision Legacy Collection

Visit the unforgiving world of the Decision Series, where survival isn’t guaranteed, and every decision counts. The Decision Legacy Collection brings together all four iconic entries in the classic franchise for the first time on Steam. Experience the series that defined action-strategy and city defense in the Flash era, now available in this 4-pack bundle.

Decision 3
Humanity’s survival rests on more than just firepower in Decision 3. Build alliances, recruit and train soldiers, and restore society from the ashes of the apocalypse. With larger maps, human allies, and an evolving zombie threat, this installment pushes you to think beyond the battlefield. It’s not just about survival anymore. It’s about rebuilding the world.

Decision
In Decision the city has fallen to the undead. Reclaim it block by block. Navigate treacherous streets crawling with zombies, uncover hidden resources, and fortify key locations. With every district you liberate, the stakes rise, forcing you to balance brute force and careful planning. This is survival at its most intense. Are you ready to face the zombie horde?

Decision Medieval
Finally, Decision Medieval takes the franchise in a new direction, swapping firearms for swordplay. Defend a kingdom overrun by mythical monsters, storm enemy fortresses, and master medieval combat in a brutal, fantasy-driven twist on the series. With siege weapons, castle defense, and a rich dark-fantasy setting, this game offers a new take on the series.

Decision 2: New City
Expanding the fight to a larger map with deadlier threats, Decision 2: New City really turns things up a notch. New enemies, advanced weaponry, and an evolved challenge await as you battle to secure a sprawling urban battlefield. Defend against increasingly aggressive zombie hordes while managing resources and militia to hold the line. And guns. Lots of guns.

The Decision Legacy Collection preserves the original gameplay of these cult classics, giving fans both old and new the chance to experience the series in its purest form. Whether you're reliving the thrill, or discovering the franchise for the first time, prepare for a journey into the heart of survival, strategy, and relentless action.
