Structures

Structures are friendly units/objects that spawn in to help you survive the wave or kill the enemy aliens. Structures can be spawned by certain Items and Weapons as seen on the lists below.

Engineering Builds Engineering Stat.png are based around having turrets and/or Landmines around, which means a lot of structures.


Improved Tools.png Improved Tools has the ability to increase the spawn rate of Garden.png Garden's fruits and the spawn rate Landmines.png Landmines. It also increases the firing rate of turrets. The amount is equal to 50% of your Attack Speed.


The Engineer.png Engineer has an ability that makes Structures spawn together in a cluster, but it doesn't affect Landmines


The Streamer.png Streamer gains +2 armor for each structure you have, granted by weapon and items you have. So even Wandering Bot.png Wandering Bot grants armor. However with Landmines.png Landmines the +2 armor doesn't depend on the amount of mines on the field, but rather just on the amount of weapons and items you have that spawns mines. The same logic applies to the Advanced Technology Achievement.


You can have a maximum of 50 Structures out on the map at once. If more spawns, random structures of yours are destroyed. Trees are not Structures. Each individual landmine counts towards this limit.

Scaling & Effects

Turrets and Landmines do not scale with Primary Primary Stats except Engineering, but do scale with Secondary Stats and other effects provided by Items.

Turrets Fire Rate

The base Fire rates of the different turrets are listed below.

You can increase the fire rate of the turrets with the Improved Tools.png Improved Tools item which makes the turrets scale with 50% of your attack speed.

Turrets spawned by Wrench.png Wrench are the same as the turrets spawns by their respective items.

The attack speed of turrets is slightly randomised between each shot to between 70% and 130% of the attack speed. So the Attack Speeds shown here are just the averages.
