Battlefield 6 Deep Six Event runs from September 15 through October 12, 2026 across Battlefield 6 and REDSEC. Progress comes from completing contracts and gathering Intel Devices, with Weapon Packages, Customization Rewards and the Royal Navy Diver’s Knife confirmed as the event reward pool.
The Diver’s Knife is the important one: EA calls it the ultimate reward for completing the full Collection Event. The individual intermediate cosmetic names are presented in the live event track rather than fully itemised in EA’s launch article, so the useful way to approach Deep Six is to understand the progression route and what is definitely at the end of it.

Battlefield 6 Deep Six Event rewards include premium Weapon Packages, Customization Rewards and the Royal Navy Diver’s Knife. The knife is a new melee weapon themed around the Royal Navy diving blade and is only awarded for completing the full Collection Event.
EA does not publish every intermediate cosmetic name in its Tidal Strike briefing, so it would be misleading to invent a complete item-by-item list outside the live event screen. The official event guide confirms the reward categories and final knife, while the in-game Deep Six page is the authoritative place to see the exact current tiles on your account.
How Deep Six challenges work
Battlefield 6 Deep Six Event progression is built around contracts and Intel Devices. EA’s guidance is to complete contracts regularly, tackle objectives with a squad, look for Intel Devices in both Battlefield 6 and REDSEC, and vary your playlists so you do not miss event opportunities.
That cross-game structure matters. You are not forced to spend the entire month in one mode. If you prefer core Multiplayer, you can make progress there; if you mainly play REDSEC, the Collection Event is also designed to move forward on that side.
The free trial can contribute to the event
Battlefield 6 Deep Six Event is included in the September 15–22 free trial through a dedicated event playlist with Contracts. Trial players can therefore make real event progress while testing Battlefield 6, then continue eligible REDSEC progression after the premium trial window closes.
That is useful because the event itself lasts until October 12. If you are starting through the trial, do not assume you have only one week to finish Deep Six. The trial ends first; the Collection Event continues for nearly another three weeks.
How to reach the Diver’s Knife efficiently
Battlefield 6 Deep Six Event rewards steady completion more than sitting in one favourite playlist and hoping progress happens in the background. Check the active event contracts before queuing, choose modes where their objectives overlap with how you already play and keep an eye out for Intel Devices rather than ignoring them as scenery.
If your only goal is the melee weapon, our Diver’s Knife unlock guide focuses on the completion requirement and deadline. The short version is that partial progress is not enough: EA labels the knife as the reward for finishing the full Collection Event.
Deep Six deadline and what to prioritise
Battlefield 6 Deep Six Event ends October 12. That date is firm in both the event guide and Update 1.4.3.0 notes, so players chasing the final reward should work backwards from it rather than assuming Tidal Strike will stay open indefinitely.
Battlefield 6 Deep Six Event is best treated as a month-long checklist: contracts first, Intel Devices whenever you see the opportunity, and the live reward track as your progress bar. The named reward categories are confirmed, the final Diver’s Knife is confirmed, and anything more specific should come from the event screen rather than guesswork.
