Opportunity Cost Analysis

What you give up by choosing eco over DPS:

Eco Choice

Buying Farm instead of Hacker

+$$$/wave after BEP - S-tier single-target DPS

DPS Choice

Buying Hacker instead of Farm

+ High burst damage - Delayed economy

Pro tip: The optimal strategy is to deploy minimum DPS to survive early waves, then funnel all excess cash into eco towers. By wave 20+, passive farm income eclipses combat yields.

Easy High — Farms scale fast Low
