Icebox

Use this Barrier Orb to create a one way angle against enemies trying to push the right side of A. You can see their feet and shoot at their legs while they can't see you

Walk on the corner next to the ramp and place a wall vertically so it extends over the ramp

Use this Barrier Orb to block off B Long ground pathways. Both sides should be blocked off, but there will be a small gap at the ends, so be careful of exposing yourself. Also note that the enemies can still get past the wall if they jump onto the containers, so you just have to watch the container angle

Place the wall so that both sides are covered, leaving only a small gap at the ends

Use this Barrier Orb to block off Tube for the attackers. When placed properly, the enemy will have to break all four segments of the wall to get through Tube, giving you much more time and info to react than a horizontal wall. You can also peek the sides if they try to break it

Place a vertical wall right in the center of Tube

Use this Slow Orb to delay the enemies from pushing through A Main near the orb

Stand in the corner in A Hell and aim at the left wall along the horizontal line

Use this Slow Orb to delay the enemies from pushing to B Site from B Long

Walk on the bridge of B container and aim at the 'K' on the Yellow container

Use this Slow Orb to delay attackers from pushing A when rotating to A through Stairs

Stand on the left edge of the doorway at Stairs and aim at the center of the tile on the wall

Use this Slow Orb to delay enemies from pushing down Mid when your teammates call for help at Mid

Stand in front of the green box in B container and aim at the top of Tube over the wall

Use this Slow Orb when the enemies are pushed B Long and around Yellow trying to take B Site. This will make it difficult for enemies to peek from Yellow

Stand at the edge of the doorway of B Hall and aim at the top of the wall towards Yellow
