Fires a laser beam that passes through entire map and causes damage to first enemy hit. It has an infinite attack distance, but a finite detection range.

Unique Characteristics

Laser has Batteries capacity as its Unique Characteristic.

Batteries capacity - the duration (in seconds) each laser beam lasts for. Levelling the tower increases Batteries capacity.

Batteries Capacity: 2.5 + 0.1/Tower Experience Level

Other Characteristics

Laser does not have attack speed stat, instead it has a "Charging speed" characteristic which is not affected by attack speed bonuses. The Charging Speed is the rate in % at which the Laser charges up to fire a laser beam. Once it reaches 100%, the Laser will aim and fire its laser beam when an enemy is in its range.

The time needed to fire the laser is as follows: Reload Time = 100 / Charging Speed %/s

The laser beam itself depends on the Battery Capacity stat, with each point of this stat indication how many seconds the beam lasts. Enemies that are hit by the laser beam take 105% of the tower's Damage stat per second.

Laser fires a laser beam that damages the first enemy it comes in contact with. The beam length covers from the tower's center point to where the beam hits its target. With High frequency, the beam can penetrate through multiple enemies, extending to the limits of the map if its pierce cap is not reached. It is possible for the beam to damage enemies that are beyond the Laser tower's attack range, though Laser will only fire laser beams if enemies are in its Attack Range.

While the Laser beam is fired, the Laser Tower normally can't rotate. Large batteries allows for some rotation once the beam has been fired, though the rotation speed is also reduced.

Abilities:

Ability	Description
High frequency	When batteries deplete, ignites X enemies in straight line fore X s. Fire deals X% * Damage * Batteries capacity damage per second
Mirrors system	Split into 3 beams, x0.45 damage each
Large batteries	Beam lasts x1.4, damage x0.85, can rotate with 10% rotation speed while shooting
Ionization	50% faster charging, each tower that stands close reduces bonus by 10% (unlocks at 10th level)
Ultimate	Every killed enemy increases the damage of the tower by 2.5% for 12s, stacks
Powerful	PWR x1.1

High Frequency decreases Laser Damage stat by 60%, turns laser beam blue, and allows the beam to hit up to six targets at a time. If the pierce cap is not met, the remaining beam continues to travel to the end of the map. Hitting the cap of enemies stops the beam at the last hit enemy. (outdated information, please update to 1.9.)

Mirrors System decreases Laser Damage stat by 55% and will fire two additional lasers. The additional lasers create a 35° angle (can be decreased with Research). Both lasers behave similar to the primary laser, applying the ability modifiers of High Frequency if it is used.

Large Batteries increases Battery Capacity characteristics by 40%, extending the duration of the beam. It also decreases the damage of the beam by 15%, as well as allowing the beam to be slowly rotated once it begins firing.

Ionization increases Charging Speed stat by 50% however any tower within 1 tile range from laser loses 10% of that bonus. Note that bonus cannot go be negative so 8 towers near laser tower does not decrease Charging Speed overall.

Strategy:

Laser Tower serves as a high single-target damage source at its base, similarly to the Sniper or Minigun towers. To vary usage between these three, the Laser changes out an aiming or acceleration mechanic for a single focused beam of damage which has a charging interval between shots. The beam itself stays in one location initially, and extends to the first enemy it hits or the level boundary if nothing else obstructs it.

These qualities allow a Laser to output a high amount of damage as long as it keeps enemies in its beam, making long lines of the track a great asset to ensure enemies are always hit once the beam is set. Changing Target priority to Last is optimal, as it makes the Laser target the furthest enemy in range, allowing it to line the shot more accurately.

Best tile placement: Damage

Damage directly increases Laser's damage output, making it the optimal choice. Range is very situational, as it allows Laser to fire earlier and more accurately, but can also make it target wrong enemies and waste a lot of potential damage.

Optimal 2 Abilities: Large Batteries, Mirrors System(required Shooting Angle Research Lv.3)

Large Batteries provides a small damage loss from the base attack, providing several situational bonuses which can make up that penalty. Extending the battery capacity allows the Laser tower to be firing off for longer, allowing it to improve its damage output by reducing how frequently it needs to stop attacking and recharge.

High Frequency sacrifices the single-target damage of the Laser tower in exchange for hitting multiple targets at once. While the damage penalty may seem bad at first, the potential benefit of multiplying damage output by up to six targets completely makes up for the initial reduction in most cases. Having a focus on multiple targets also makes the positioning of the Laser tower even more crucial, where straight lines of oncoming enemies maximizes the amount of targets hit every shot.

The second bonus is being able to continuously aim the beam at targets, which can allow a beam to remain on a single enemy for longer and increase overall damage. For strategies with High Frequency however, following a target as it possibly moves away from the corridor poses an issue, making pairing with that ability precarious.

Mirrors System makes the tower fire 3 laser beams with 45% damage each, potentially granting a 35% damage increase with all three beams connecting to targets. The issue is that those added beams are fired off away from the target, making aim and contact with enemies too cumbersome to make the 2 additional beams useful.

There is notable conflict with High Frequency, as aiming down a long track fires the added beams off to hit nothing, serving to reduce the overall damage output of the tower. The only potential use of Mirror Systems is when not using High Frequency, where hitting three targets in a corner is much more feasible.

Ionization reduces the time needed to charge the next shot by 50%. This bonus is reduced down to a minimum of 0% if adjacent towers are placed, making a lone Laser at the end of a track or isolated away from the rest of the defensive line more desirable. Boosters are not considered for this ability, making separation of towers to make the best use of boosters is doubly helpful for Laser towers.

Advinas Dialogue

5.7

Advinas: The finale is near, and I have something very powerful for you - the Laser.
Advinas: The main great advantage of this tower is that the beam crosses the entire map and causes damage to all enemies through which it passes.
Advinas: It can cause really huge damage, not comparable to the damage of any other tower, but still it is not perfect
Advinas: This tower has a small rotation speed and it cannot turn while the laser is active.

Trivia

• Along with Flamethrower, Gauss, and Crusher, Laser is one of the four towers not present in the first Infinitode game.
• Before the 1.8 Update, the Laser tower behaved radically differently than its current version.
  • Its laser beam originally dealt less damage, but penetrated a seemingly infinite amount of enemies at a time, doing so without any abilities required.
  • High Frequency originally gave the Laser tower 300% damage in exchange for hitting only one enemy at a time.
