Laser turret

Laser turrets are an advanced defense building with longer range than the gun turret, laser damage, and use electricity to operate instead of ammo (and a smaller amount of energy when idle). Each shot costs 800kJ of energy; as the shooting speed increases through upgrades, so does the power required to keep firing.

Using laser turrets to ward off attacks can cause electricity usage spikes, these can be offset by using accumulators (or steam storage and excess steam turbines).

On space platforms, lasers can be effective against small asteroids, which have only 20% laser resistance and 100 health. Other asteroids have laser resistance of 90% or more, making lasers relatively useless against them. Large groups of high quality lasers (which have extended range, not damage) can be useful against medium asteroids if they also have enough damage upgrades.

Pentapods on Gleba have high laser resistance (50% for wrigglers, strafers, and egg rafts, 80% for stompers) so laser turrets are ineffective against them.

The demolishers on Vulcanus have 100% laser resistance.
