The Freelancer in the middle is receiving the benefits of cover
Objects and walls on the map are considered to be
. A Freelancer directly behind
reduces the damage from attacks coming from that direction by 50% (though some attacks are only reduced by 25%). Cover is granted against attacks coming from the front of the cover and roughly 45 degrees to either side. Protection is not granted against attacks from the square on the opposite side of the cover.
Walls[]
Tall cover or walls can also serve as cover and often can also serve to avoid attacks altogether. As with regular cover, attacks that hit a Freelancer from within 45 degrees to either side of the cover confers the damage reduction. As the walls also block vision, they also block most attacks and projectiles. This means that they can be used to deny enemy Freelancers the opportunity to attack in the first place. Clever positioning around walls and cover can allow a Freelancer to attack another while avoiding being exposed to the fire of more than one or two enemy Freelancers.
Indicator
An indicator showing that this space provides cover
When planning where to move during the Move Phase it is important to consider your cover options. If you want to know which spaces provide cover simply move your cursor over them and if it is a space that provides cover it will give you an indicator showing you which direction it provides cover from.
