Icebox

Use this teleport to cross between back B and B site at Fence. As a defender you can use this to mix up your angles when the enemy are still pushing B Long and Yellow, or as an attacker to quickly cut off rotates at defender spawn

Use this aggressive teleport at the start of the round to peek enemies at Mid from ontop of Tube. Combine this with a falling smoke before teleporting so the enemies cannot see the teleport animation

Aim the smoke at the path left of Tube and move it up until the center is next to the top of Tube and use it immediately. Then wait a second for the smoke to pop and jump off the Kitchen step to teleport ontop of Tube

Use this smoke to create a oneway angle against the attackers at B Long. It will oneway both the doorway and the corner, and even the garage if you peek the left side under Green

Aim the smoke at the center of the garage doorway, and then move it up until you see the green arrow on the door frame

Use this smoke to create a oneway angle in Tube against attackers trying to peek or push Tube. You should be able to see their feet under the smoke while they can't see you

Aim on the roof of the bottom end of Tube, and place it towards the right side so the smoke creates a gap on the bottom left
