Top-down zombie horde survival

The camera looks down on the survivor and the fight. On desktop, WASD moves, Shift sprints, and the mouse aims and fires. You can move in one direction while pointing the rifle in another, which matters when zombies approach from different sides. Sprinting creates space, but it is slower while firing, so choose when to reposition and when to plant your feet for a shot.

On touch screens, a left stick handles movement and the FIRE control shoots. Holding FIRE aims at the nearest living zombie automatically. That keeps the controls manageable on a phone while preserving the central survival decision: do you keep moving around the crowd, or spend a moment firing into the nearest threat?

Kills earn experience during a run. In a campaign deployment, each level-up offers two battle cards and one shelter investment. The battle cards can improve the rifle: Hair Trigger fires faster; Heavy Rounds adds damage and knockback; Split Shot adds two rays per rank. Other options increase magazine size or range, create an impact burst, or let shots ricochet from solid surfaces. If the weapon perk pool is exhausted, battle cards can instead restore health or add reserve ammunition.

Only the battle cards change this run’s combat. Faster shots increase output but still use ammunition. A larger magazine means fewer reload interruptions, while Split Shot spreads rays and can help cover a wider approach. Impact bursts reward hits near clustered enemies, but walls and cover can block the blast. The separate shelter card alternates with level: one banks research and scrap permanently, the other boosts passive shelter production for a limited time. No single pick removes the need to move, aim, and reload at the right time.

Sector battles have a clear finish: survive three waves to secure the operation and advance the campaign. Each wave sends a growing group of zombies into the arena. Clearing a wave brings a short pause before the next one and restores some reserve ammunition. Take that gap to read your health, current build, and space around you before the next crowd arrives.

Scavenge is the open-ended option. It has no final victory wave and no extraction timer; you decide how long to keep going. Enemy numbers and combat pressure rise with each wave. The active enemy population has a 70-zombie cap, but that limit does not stop enemy strength from increasing. Cleared waves contribute food, ammunition, energy, and scrap to the recovery bundle when the run ends.

Battle cards shape the current fight and reset when the deployment ends. The third card at a campaign level-up is a shelter investment, not another weapon perk. These alternate by level: Recover Field Supplies banks research and scrap in shelter storage, while Overclock the Shelter boosts passive production for 30 minutes in a sector run (10 minutes in Scavenge). The timed boost can extend to a two-hour cap. The campaign also carries lasting progress between deployments through equipped weapons, research, modules, shelter technology, and provisions.

Between fights, shelter management gives the campaign a reason to revisit sectors and try another build. A failed deployment does not erase shelter upgrades or residents, though a sector defeat can levy some stored supplies. Scavenge provides a separate recovery route: supplies earned per cleared wave are awarded when the run settles, whether it ends through defeat or retreat.
