"Future warfare! Lazor beams burn through any target, causing moderate damage to all enemies in its path."

Mark 1 Mark 2 Mark 3


  • The Lazor Beam is a Prototype Defense that is built in the Weapon Lab.
  • Like all Prototype Defenses, it will only last for a certain amount of time after it is placed on your base.
  • The Lazor Beam fires a red laser that hits all troops within its linear trajectory and extends beyond its own detection range within map boundaries.

Offensive Strategy

  • The Lazor Beam's main purpose is to invalidate strategies that involve frail backline units, such as Bombardiers. Zookas and Laser Rangers. If its damage is sufficiently boosted by Ice Statues, it can pose a threat to Riflemen, Warriors, Medics and Cryoneers. Conversely, more durable units like Tanks can almost ignore its presence.
  • Scorchers and Incinerators are good against Lazor Beams, as their tendency to wander around may draw the Lazor Beam's attacks away from DPS troops.
  • It is possible to confuse Lazor Beams with Smoke Screens, but this can be inconsistent. If even one target appears within its range, the defense will fire and hit all other troops that happen to be in its way, regardless if they are visible or not.
  • The laser is able to hit troops under Smoke Screen, provided if there is a target for it to attack.
  • Using Critters near the Lazor Beam can force it to target the Critters. Place them away from your troops, preferably to the side or behind, so the Lazor Beam does not hit your troops, but close enough so the Lazor Beam attacks the Critters in the first place.
  • If the Lazor Beam is placed behind the Headquarters or Power Core, some troops can actually outrange it. They should not be paired with troops that have lower range, as this will then enable the Lazor Beam to reach them.

Defensive Strategy

  • This defense is best for defeating Zookas, so place it away from other defenses that are best at dealing with Zookas such as Rocket Launchers.
  • A Lazor Beam may help some in defending from a Warrior attack, but generally, a Damage Amplifier, Shock Blaster, Hot Pot, or Microwav'r will help more.
  • If you are frequently attacked by the Smokey Heavy-Zooka attack strategy and the Lazor Beam just didn't work out against them, make sure it can cover all sides of the Headquarters.
    • Try to place the Lazor Beam where the Heavies will be between it and the Zookas in a Smokey Heavy-Zooka attack. This way, the attacker will have to use an extra Shock Bomb to disable the Lazor Beam because it is the only defense that Heavies cannot protect Zookas from.

Version Differences

  • At Mark I, the Lazor Beam is a circular stand with a pole on which a radial dish is present. There are 2 Power Rods propped up against it, and another one inside it. The interior power rod has 2 grey tubes connected to it, which are in turn connected to a small grey box.
  • At Mark II, the circular stand gains several structural supports in a ring around it. The Power Rods are replaced by a black box. The original box is now on the ground. The base's color gains a blue tint.
  • At Mark III, the framework gains heavy metal plating with yellow outlines. It gains a small yellow door with a ring on it. The black box propped up at the side of the Lazor Beam is removed.
