Connect recruitment to the boundary enemies must not cross.
The objective has a visible boundary
MineWar Soldiers vs Zombies describes positioning soldiers and preventing zombies from crossing the defensive line. That line gives purchases and placements a concrete purpose. Before adding another unit, identify which part of the approach is insufficiently covered in the actual scene. More units in an already comfortable area may leave the important gap unchanged.
Read a unit’s role before selecting it
The source distinguishes soldiers with different skills, including shooting and fighting. It does not supply a reliable counter table or range statistics. Read the offered unit information and connect it to the pressure near the boundary. This makes a recruitment choice easier to evaluate than selecting purely by appearance or assuming that a more expensive option addresses every threat.
Include collection in the defensive plan
The description says defeated enemies leave coins and diamonds that fund further soldiers. If the running game requires an action to collect them, consider how that action fits the immediate defense rather than looking away from the line indiscriminately. Verify the listed right-click or touch behavior in the interface. This note supplies no tested deployment order, income formula or guaranteed wave solution. It uses the stated boundary to make one local defensive decision clearer.
