Kill Them All (v1.0.1)

Serenity Island is collapsing under an epidemic that turns its population into a violent, unpredictable threat, and the authorities lack the force needed to contain it. You play a hired mercenary sent into the quarantine zone to complete dangerous assignments while the situation deteriorates around you. Kill Them All frames its action with a bleak survival-horror mood: ammunition feels precious, infected crowds are relentless, and the job regularly demands more nerve than firepower. Its linear campaign keeps the pressure focused on pushing through hostile areas rather than wandering a vast open world.

Missions revolve around clearing infected, reaching objectives, escaping faster Runner enemies, and surviving encounters with tougher riot-infected opponents. Combat is built around managing firearms and magazines carefully, since blindly unloading ammunition can leave you exposed when another wave arrives. Successful operations earn money, while scavenged materials give you the means to craft supplies that are unavailable in the field. Between deployments, equipment upgrades and headquarters improvements provide a clear sense of progression, letting you tailor your chances against threats that steadily outclass your starting gear.

The strongest hook is its balance between direct, satisfying infected-slaying action and the caution imposed by limited resources. Rather than presenting the player as an unstoppable soldier, it makes retreat, preparation, and smart spending part of the mercenary fantasy; there is always a nastier enemy waiting beyond the next objective. Serenity Island’s outbreak premise is familiar, but the focus on upgrading a base, crafting essentials, and confronting several distinct infected types gives the campaign a practical survival edge. It suits players who enjoy compact action games with zombie-horror tension, especially those who prefer a mission-driven structure over the sprawling exploration of games like Dying Light or State of Decay.
