Pipes are terrain over which no unit may cross (with the exception of Piperunners). This changes the dynamics of a particular front in the same way mountains and rivers shape land combat; only, this applies to all units. In addition, pipes serve as obstacles for air units. This prevents air units from locking other production facilities or reaching the front too soon.

Pipes also have a unique property in AWBW where they are visible at all times to all players during Fog of War. Any unit on a Pipe or Pipe Seam can be seen by everyone - this normally includes only Piperunners, but can also apply for some predeployed units on the map placed on Pipes. Broken Seams will have this vision removed.

Pipe Seams have the same characteristics as Pipe, but they may be broken by units. Each has 99 hit points. Often, Pipe Seams are used as a gate to a front providing either an alternate route or access to bonus/key properties. Once broken, the Seam turns into a Broken Seam, which serves as a Plains tile. When a Seam is broken, a Piperunner may not traverse it, but any other land/air unit may. For design purposes, a map revolving around a Pipe Seam is likely to be chokey, possibly resulting in stalemate.

Pipe Seams have 99 hit points and the same defensive value as a 100/100 Neotank on 0 star terrain. Luck damage does not affect them, though any CO attack bonuses and owned Comm Towers still will. Below is a list of the base damage (no attack boosts) that each unit does to a Pipe Seam:

5	40	20	50	90	1	45	15	115	55	50	1	50	60	15

Artillery are the most cost-efficient method for destroying early Pipe Seams, able to do so in at most 3 hits - COs that are capable of gaining a 25% attack boost or higher, such as Lash or Kindle on a property, are able to do so in just 2 hits. In the late game, Bombers are the most efficient way to destroy pipe seams for most COs, only needing a single Comm Tower boost to destroy the Seam in one attack, though Md. Tanks and Neotanks remain reasonable choices without sacrificing too much momentum.
