Engineer

Overview
The Engineer is a unit that carries over from the original game, The Conquerors. It's considered a support unit and is produced in the barracks. The Engineer's sole ability is to construct walls between wall columns. Engineers are particularly useful when making megabases, as walls can temporarily stop or trap land units as defensive buildings attack them. Engineers cannot be produced until the player has finished researching walls.

Usage
Though the Engineer unit has one ability, it's use is versatile. Engineers are mainly used in the Survival game mode. Some players will construct walls around their buildings to avoid them being bombarded by the AI units. Others partake in a collaborative effort to make layers of walls on the AI path to stop them from reaching the center. Engineers and walls are less commonly used in conquest, but are sometimes used as base defense or to lead land units to or from certain base areas.

Strategies

 * When using Engineers, you are allowed to experiment with the length of your walls. Making a wall with many different wall pieces is far more effective than making a wall made out of just a few pieces. It is also ideal to place at least one bunker in front of any walls to keep them standing longer (for even more efficiency, try having repairmen constantly repair the bunker).


 * Wall segments can form different types of walls. Having slightly curved walls are more productive than completely straight walls in most cases, as they will trap units, versus completely straight walls where units tend to slide towards the end and walk around.
 * If the Engineer isnt making any walls try moving it back and forth between the wall columns to make it work again.

Trivia

 * Until the 4v4 update, players were able to train Engineers in barracks without having walls researched. It is now required to research walls before being able to have Engineers.
