Walls

Overview
A Wall is a researchable feature that carries over from the original game, The Conquerors. It needs at least one Engineer and two Wall Columns to be built, you can place up to 16 Wall Columns. Its main purpose is to defend important buildings or make huge, well-protected, bases. Just like Landmines, walls have their own capacity limit rather than adding up to the building cap. Walls can only obstruct ground units, thus, aerial units can easily bypass them. (Assuming that the wall is built on ground-level)

Usage
Walls have other uses rather than just stopping the enemy or protecting your base, they can be used as a distraction for your base or to claim certain territories, although, they're way more useful when used as a defensive building, walls can hold the enemy units while HQs, CCs or even Forts kill them.

If one wants to make walls, they'll have to complete the following steps:
 * After researching walls, place two Wall Columns(that can be found in the Building Tab) down, leave a gap between them.
 * Move an engineer to somewhere near the two columns, if there are more columns connected, the engineer will probably make multiple walls, also, the more engineers you have the faster the walls will build.
 * Your wall should be done by now, what you can do is just sell the two columns used to make the wall, as they don't have much health, your wall will still the same, as selling columns doesn't do anything.
 * After all these, you can make a Gate, they cost 30$ to make and can be enabled/disabled, everything gates do is make it so units can pass through it, useful if you want to cover your whole base with walls.

Strategy

 * If you want your wall to last longer, especially in Survival matches, you can always put buildings in front of them, like Bunkers, so the troops don't focus their fire right on the wall.
 * Having a repairman army repair the bunkers makes this strategy more effective.
 * Walls can be utilized in various defensive ways, other than being an added layer of protection for a base, they can also be used for stalling, especially on chokepoints, or to blockade off an enemy path.
 * Walls built on high ledges can prevent planes from reaching your base.

Trivia

 * Walls were also in The Conquerors, The Conquerors 2, and The Conquerors Mark 2.
 * The Wall Column has the lowest health out of all buildings in the game.
