Structures

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

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

The Engineer has an ability that makes Turrets spawn together in a cluster, but it doesn't affect other structures.

The Streamer gains +2 armor for each structure weapon and items you have. So even Wandering Bot grants armor. However with 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.

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 item which makes the turrets scale with 50% of your attack speed.

Turrets spawned by 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.

Turret	Atk. Speed
Turret	0.73s
Incendiary Turret	0.28s
Medical Turret	2.2s
Laser Turret	0.87s
Explosive Turret	0.87s
