NWars:Plains

Plains is a type of terrain in all installments of the Nintendo Wars series.

Purpose
Plains are commonplace on most land maps, since Roads wouldn't be everywhere. Tanks are indiscriminate between the two terrain in terms of Movement. Of course, Plains don't provide much terrain assistance.

In Famicom Wars and Game Boy Wars 1/2/Turbo, Plains and Roads have the same movement costs. This isn't the case in any of the later Nintendo Wars games; units that move on Tires are slowed down in Super Famicom Wars and the Advance Wars series. In Game Boy Wars 3, all unarmored land units except the Battle Car move more slowly.

Plains is one of the two types of terrain that gives a stronger defense boost to foot soldiers than vehicles. The other one is the Forest terrain.

The Constructor can use Establishment to make Forest or Wasteland into Plains, or Pave a Road over Plains. A Simple Airport can also be created in place. However, Bombing will turn the Plains into Wasteland.
