ESN TOWERS
Hold the line. Twenty waves. Two bosses. Three maps.
Pick a tower on the bottom bar, then click or tap an empty tile to build it. On a phone, tap once to preview the range and tap the same tile again to build.
Tap a tower to upgrade it (twice), change who it aims at, or sell it. Selling before the next wave starts gives every coin back.
Start Wave sends the next wave. Every kill and every cleared wave pays coins. Do not let enemies reach the core.
