'''Walls''' provide basic damage protection against [[enemies]]. They are used to protect fragile targets from advancing enemy forces, and extend the amount of time defensive structures like [[turret]]s have to kill the enemy.
'''Walls''' are a defensive structure that prevents both the player and [[enemies]] from passing. They are primarily used to shield [[turret]]s so they will be able to fight enemies longer without being destroyed, and can be used to protect parts of the factory from enemies.

Walls do not block projectiles, however, allowing both the player and enemies to shoot over the walls at nearby targets. Ensure that all walls built are far enough away from precious machines so they cannot be damaged over the walls. Due to projectiles' ability to fly over walls, [[turret]]s built behind walls will be able to shoot at enemies. This is optimal, as it allows turrets to avoid damage from melee fighters, which must break through the wall to attack targets behind it. Although, care should be taken as the game progresses and enemies evolve because [[Enemies#Biters|big and behemoth biters]] can attack 2 tiles away, meaning they can hit structures directly behind a single layer of walls. To prevent this, structures can be moved further back from the walls or a second layer of walls can be added.

Walls are a defensive structure that prevents both the player and enemies from passing. They are primarily used to shield turrets so they will be able to fight enemies longer without being destroyed, and can be used to protect parts of the factory from enemies. Although walls have less health than most defensive structures, their high damage resistance means it will take longer for enemies to destroy them.

Gates can be constructed to allow the player to pass through walls. Gates share the same health and resistances as walls and automatically close for enemies if not connected to the circuit network, so no defensive power is lost.

Walls only block melee attacks, projectile attacks go over them. However, big and behemoth biters can attack 2 tiles away, meaning they can hit structures directly behind a single layer of walls. To prevent this, structures can be moved further back from the walls or a second layer of walls can be added.

Despite their applications as a defensive measure, walls are not considered a military unit and structure; this is important for understanding the behavior of enemies regarding walls. If they are attempting to attack something and the wall obstructs their path, they will attack the wall to destroy it and clear the way. However, if they have already been aggro'd by a turret or the player, enemies will more actively pursue their aggressor and not necessarily attack walls between them. This allows the player to stall enemies more efficiently by building walls in a manner that disrupts their pathing without entirely obstructing it. A common means to achieve this is a pattern of walls in a cross-shape, arranged so enemies must navigate between them.

Note that this does not mean enemies will entirely ignore walls - if their pathing is disrupted significantly enough, they will simply attack the wall itself. This means that building mazes of walls or long sections of wall with a gap between them will not be effective. Such usage of walls is not a reliable substitute for walling off turrets, and sufficiently large groups of enemies will inevitably get through the network of walls due to sheer numbers.

Placing walls in four adjacent tiles forming a square will cause the inner space to be filled. This is only a visual property, the health and the rest of the properties of the walls are not affected.

History

  • 0.15.0:
    • Doubled stack size of walls, to 100.
    • Walls with gates now can accept any signal type.
  • 0.13.5:
    • Increased the collision box of walls slightly.
  • 0.10.2:
    • Repair speed is twice as fast.
  • 0.10.0:
    • Changed collision box logic. It is possible to walk between diagonal walls now, but not when connected.
  • 0.7.5:
    • Doubled the stack size of walls.
  • 0.7.1:
    • Walls now leave remnants when destroyed.
  • 0.7.0:
    • Increased wall health from 200 to 350.
  • 0.4.0:
    • Added textures for a single piece of wall.
