I made this guide by analyzing games with chamber on Fracture made by Tenz and Tarik, by choosing the most used setups, and I tried to explain them at the best of my understanding. (Sorry if my English isn't the best)

ATTACK:

1- A-main:
Place a trap Spawn to cover flank, fight for control of Hall, then place TP behind the wall close to main, fight for control of A main, place tp before entering, and then fight for site with tp in case of threat.

2- A-sand:
Place a trap Spawn to cover flank, fight for control of Hall, then place TP before the door, open door with your teammates, before walking up place other tp, fight for control of sand with your TPs, after walk up to site from sand.

3- B-main:
Place a trap spawn to cover flank, fight for b-main control, place TP at the entrance of underpass, place second TP at the end of b-main, fight for site with your TP.

4- Short peek:
Place a TP before the barrier, and the other one attached to the barrier. The idea is that you can peek while being relatively safe with your TPs. This play is made in every site, and can be used for different maps as well. As an example i’ll post the B-main case.

DEFENCE:

1- A-sand/drop:
Place a trap drop to gather infos, place a TP on top of the double box sand, place the other one CT near B-link and then teleport on top of the box, after that retake the TP under you, and at the start of the round place it again on top of the boxes, but in the corner near the wall, to make it less visible. Your plan with this setup is to defend sand with an off-angle, and you can also defend drop by holding it or with a more passive angle waiting for them to drop. In case you get overwhelmed or they fast push B you can fast rotate with your TP.

2- B-arcade/main:
Place a trap drop to gather infos, place a TP B-link and the other one near the entrance to arcade. Your game plan is holding arcade with your TP, and in case no one is there you can turn around and hold B-main from a more defencive angle while still having your TP for necessity.

3- A-main to link:
Place a trap drop to gather infos, place a TP A-Link, or you can place it on top of the double box sand, and the other one A-main, you can place it behind the box or more forward, depending if you want to peek more aggressive or more passive. How you want to play this is holding or peeking aggressive A-main with your TP, and if they are rushing B you can always TP to link to rotate faster.

4- A-main to site:
Place a trap drop to gather infos, place a TP site, on top or under, depending how you want to play it, place the other TP A-main, you can place it behind the box or more forward, depending if you want to peek more aggressive or more passive. How you want to play this is holding or peeking aggressive A-main with your TP, and then play from site.
