Beginner field guide

1. Learn the two-resource loop

Your base generates money and energy. Before buying rapidly, identify which actions consume each resource and which upgrade improves generation. Save enough to keep both loops moving.

2. Establish a dependable army

Roll soldiers to create a functional wave-clearing core. Do not assume rarity alone makes a unit best: watch its real performance against the current zombie wave.

3. Upgrade the failing part

If enemies reach the base, compare field damage and defenses. Strengthen the point that is actually causing the loss instead of spreading currency evenly.

4. Expand after stability

Base expansion adds room for growth, but an expanded weak base is still weak. Push outward when current waves are controlled and your income supports the next layer.

5. Treat heroes as focused investments

Heroes are confirmed roll rewards. Because no reliable public hero stats were available at verification time, test new heroes in your own runs before spending heavily.
