…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

Écu (Light or Medium Arm Shield)

The Écu shield is one of two shield armaments in the game (the other being the Ancile). It will block damage from guns 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 robot and the shield. 

To block damage 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 since 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.

Shield is ONE-SIDED, i.e. it fits only the side (left\right) you bough it to. It will fit any robot, however, if you use correct side.

Until confirmation from developers (see atÉcu)
