Personnel Files

39 confirmed entities, sorted by threat class. Read the wave preview before every stage and build accordingly — the building is counting on you.

Bug class

Small, numerous, cheap to kill one at a time — the danger is volume.

Bug Germ

Germ

“Escaped from the breakroom fridge.”

Bug Spider

Spider

“Lives behind the server rack.”

Bug Bee

Bee

“Read an email about synergy. Furious.”

Bug Gold Star

“The brand refresh nobody asked for.”

Bug Gnat

Gnat

“A single crumb summons two hundred more.”

Bug Roach

Roach

“Cheap, boxy, and there are always more behind it.”

Bug Kamikaze Mosquito

Kamikaze Mosquito

“Volunteered for this mission. Nobody asked it to.”

Fast class

Sprints past slow towers. Laser tracks them; splash damage usually lands too late.

Fast Rocket Intern

Rocket Intern

“An overcaffeinated intern.”

Fast Org Chart

Org Chart

“The org chart, visualized.”

Fast Reply-All Chain

Reply-All Chain

“Hit the wrong button. Now everyone knows, forever.”

Beast Layoff Crows

Beast Red Tape Dragon

“Hoards nothing but unread emails and unopened memos.”

Armored class

Shrugs off most damage. Save Electro and Laser towers for these.

Armored Filing Box

Filing Box

“A filing cabinet that gained sentience.”

Armored Snowman

Snowman

“The AC was set too low. Far too low.”

Armored Snail

Snail

“Approves expenses at its own pace.”

“Reports directly to a manager who reports to no one you've met.”

Ghost class

The Ghost tower is the only real answer — everything else barely scratches them.

Ghost Ghost

Ghost

“A former employee. Still attends meetings.”

Ghost Arcade Ghost

Arcade Ghost

“It haunts the arcade in the basement.”

Ghost Overtime Wraith

Overtime Wraith

“Still at the desk long after the lease expired.”

Ghost Melting Wraith

Melting Wraith

“Left the AC off over the long weekend. Never recovered.”

Ghost Deadline Past

Deadline Past

“It already passed. It's still coming.”

Special Behaviors

Any of the above can show up carrying one extra trait on a given wave — the job board flags it before the wave starts, and the enemy itself carries a visible tell.

Shield

Wrapped in a personal energy shield before its real health even starts taking damage. Burn through the shield first — Laser and Electro cut through it fastest.

Burn (Fire)

Already alight, taking damage over time on its own. Water towers douse it outright; leave it be and it may finish itself off before it reaches the exit.

Split

Bursts into three weaker copies on death, each a fresh chance to leak. Pop it somewhere your towers can clean up the spread, not right next to the exit — letting the original walk past whole costs as many hearts as itself plus all three children combined.

Fly

Ignores the maze entirely, flying in a straight line from portal to portal with a visible shadow underneath. Only Bug Spray, Laser, and SloMo can reach it — Bug Spray hits flying Bugs hardest, Laser hits every other flying class hardest, and SloMo's slow field reaches any of them regardless of class, though it deals no damage either way.

Kamikaze

Also flying, but it isn't headed for the exit — it beelines for the nearest Laser tower and destroys it on arrival, no refund. Shoot it down first if you can. If there's no Laser anywhere on the map, it just heads for the exit instead, same as any other flier.

Building a counter

Every stage's wave preview tells you what's coming and which class it belongs to. Cross-reference against the Equipment Locker — a maze built entirely of M1 Canons will struggle the moment a Ghost or Armored wave shows up.
