…Shield should be turned towards the attacking unit to take effect. Has its own durability and can be destroyed. Does not protect against area damage of weapons… – in-game description


The Ecu is a light or medium physical shield.


This shield is one of two shield armaments in the game (the other being the Ancile). It will block damage from kinetic and energy weapons, as well as homing missiles (though it is harder due to the angle of the projectiles), but not from unguided rocket fire – these cause splash damage which damages BOTH the robot, and the shield. However, it takes double damage from kinetic weapons, and due to the nature of this weapon type some stray bullets/particles can damage a large framed shielded robot.

To block damage the pilot must rotate their robot's torso so that the shield faces towards the incoming fire. Even then, this is no guarantee of blocking all damage. 

The Écu is unique in the game, because it may be mounted on both light or medium hardpoints. However, it may only be mounted on ‘arm’ hardpoints and not other points.

The shield can be used to protect yourself while reloading.

After the shield's hit points are depleted, it will be destroyed and break off like a destroyed weapon.

The shield only fits the side (left or right) it was bought it for. Meaning, it can fit on any robot that is Ecu compatible, however, for example, if the original shield was bought on the left side of a robot, that particular shield can only be used on the left side of any compatible robot.

The Ecu Cannot Be Mounted On
