For me it's:

Battlefield 1: An Escalation

RADIO TOWER

Press each of the 9 metal cases once, in any order.

Press the hidden House Switch once.

Press each of the 9 metal cases once, in any order.

Press the House Switch 4 times.

Go prone next to the radio tower's base and record your round-specific morse code

LIGHTHOUSE
Break the 6 hanging lanterns mentioned earlier.

Insert your 5-letter string obtained from the morse code inside this sequence: CAEEB#####FEAADDAD (Replace ##### with the 5-letter string)

Input the resulting sequence into the lighthouse using the switches, with each letter in the A-F range mapped to each switch in order, from top to bottom. (Top switch is A, bottom switch is F)

Once you press the final switch (D), all Lighthouse switches will no longer be interactable.

When the Lighthouse switches are no longer interactable, a glowing cylinder attached to the big pulsating light at the top of the Lighthouse will become interactable, only for 1 minute after the Lighthouse switches have been deactivated. If you do not press this final button within the 1-minute time frame and the interaction prompt disappears, you will have to repeat the whole process in a new round.

Once pressed, a smoke grenade will appear and you will hear the familiar ominous, confirming the successful completion of this puzzle.
