Drag anywhere on the battlefield and your whole squad moves with your finger across the three lanes. The soldiers aim and fire on their own, so positioning is the skill — line them up on the lane that needs them and away from what is about to hit.
A zombie horde in many forms — fast runners, heavy brutes, exploders, shielded walkers and toxic spitters — plus a boss at the end of every level. There are six boss types (laser, siege, summoner, charger, shield plate and howler) and ten chapter warlords; each has an attack you can read and step out of.
During a battle: shoot gates to charge them (more soldiers or stronger shots), grab power-ups and pick one of three Field Upgrade cards after every wave. Between battles: spend coins on permanent upgrades and wood and steel on your five buildings (Headquarters, Barracks, Refinery, Tech Lab, Armory). Commander Rank, Weekly Operations and daily rewards add more.
Each permanently strengthens your army. Headquarters raises base health, Barracks gives you more starting soldiers, and the others improve your resources and stats. Your camp grows visibly as you upgrade them.
An endless mode you unlock as you progress: a boss every 5 waves, a warlord every 10 and a Field Upgrade after every wave. Your best wave is saved, and each run pays coins and materials.
A defeat still banks part of the coins and materials you collected, and the defeat card tells you what got through and what to upgrade first. Spend on that upgrade, then try again — after two defeats on the same level two extra rookies join your squad for the next try.
