Choose one card, then tap a grid tile. The other four become blockers.

TECHWAY DEFENSE

Build the circuit maze. Each build phase gives you five cards. Every card shows a tower and an enemy type. Place exactly one tower to commit that enemy to the next wave; the four unchosen cards become inert tower blanks. Creeps must always have a route through the waypoints, but they will reroute around anything you build.

Every wave contains one enemy type. Survive all 100 by shaping the maze, choosing the right tower, and reacting to the enemy shown on your card.

FIELD MANUAL

Build: Each of the five cards pairs a randomized tower with a randomized enemy type. Choose the tower/enemy tradeoff you want, place that tower, then place the other four cards as blank blockers.

Maze: Ground enemies travel from the input port through three waypoint gates to the core. You may redirect them, but never seal every valid route. Air units ignore your maze.

Upgrade: Select a tower and upgrade it five times. When upgrading from level 3 to level 4, choose one of two permanent TECH PATHS. Hover a path to see its exact effect. Choosing one permanently removes the other.

BUILD HAND

OBJECTIVE
Protect the core through wave 100.

Ground units must touch each glowing gate in order. Flying units take a direct route.

CARD PHASE
Each card = one tower + one visible incoming enemy. Choose one; the other four become blanks.

Pulse Shooter, Smart Missile, Tri-Shooter, EMP Tower, and Sky Salvo can engage Flyers.

TECH PATHS
The L3 → L4 upgrade forces one of two permanent specializations. Hover either choice for its exact effect.
