In Circuit Keep, your towers don't block anything.
A wave spawns. Enemies pathfind straight across the grid toward your
CORE
. They walk over every module you placed. The only thing that makes them change direction is a wall. So you build the maze, line it with firepower, and force every wave down a path you chose.
Then they start pushing back.
INTRUSIONS THAT FIGHT BACK
Each intrusion breaks your defenses a different way.
PHASE
turns intangible mid-wave and slides straight through your walls.
HOPPER
vaults over walls and air gaps entirely.
SCRAMBLER
drags down the fire rate of every module near it.
PARASITE
skips your CORE and drains your CHARGE NODES instead.
BREAKER
exists to eat your walls.
KERNEL
, a boss, forks child intrusions to overwhelm you from multiple angles at once.
No two waves play the same way.
TOOLS TO FIGHT BACK
FOCUS FIRE
: Mark any intrusion with a crosshair and every module in range locks onto it immediately.
OVERDRIVE
: Permanently boost the damage of an entire module family.
OVERCLOCK
: Speed up your economy, cooldowns, and modules for a short window when you need it most.
BUILD YOUR MAZE
Place
FIREWALLS
to reroute intrusions exactly where you want them. Your modules run on power, so placement matters as much as firepower. Every wall, every turn, every module position is a decision.
THREE ACTS. 40+ LEVELS. ENDLESS MODE.
A hand-crafted campaign introduces each module and intrusion one at a time across three acts. Struggling? Spend permanent upgrades on the
RESEARCH GRAPH
. Want more? Switch any level to
HARD
mode. Want to go as far as you can? Enter
ENDLESS
mode with everything unlocked.
WHAT IS IN THE BOX
12 module families with branching upgrade paths. Two paths per module, each with its own payoff: crit, knockback, extra targets, and more. Switch paths any time.
Four damage types:
KINETIC
,
THERMAL
,
ELECTRIC
, and
CORRUPTIVE
, each with status effects that stack and combine.
12 intrusion families, 7 elites, and 3 bosses.
No fixed loadouts. No RNG drafting. Every module you have unlocked is available every wave.
