The Community Test Environment (CTE) is a feature available in Battlefield 4 and Battlefield Hardline. The feature allows players to test new gameplay features that may be added in future patches on servers separate from the base game they are played on.
Introduced to Battlefield 4 on May 8, 2014 for PC and Xbox One on July 6, 2015, the feature was developed by DICE Los Angeles to get feedback directly from the players themselves and adjust gameplay accordingly in response to the numerous issues that plagued Battlefield 4 after release as well as help in the development of Battlefield Hardline.
The feature puts players in a completely separate version of Battlefield 4 and Battlelog, requiring players to create new soldiers in order to participate. As such, gameplay within the CTE does not affect a player's soldier in the actual game. While the CTE is only available on PC and Xbox One, DICE LA plans to eventually implement changes to all platforms. The CTE is currently only available for Premium players due to limited space, though DICE plans to make it available to all PC players in the future. Premium members on consoles also have access to the Community Test Environment on PC and do not need to own a copy of the game.
On March 11th, 2016 DICE LA confirmed that the Battlefield 4 CTE would no longer be receiving any new updates.

The CTE is updated with new initiatives in regular intervals which control which servers are up and running, and what game-modes are available to play at any given time. So far, two initiatives have take place.
Initiative #1: “Netcode” improvementsEdit
The first initiative was focused on network improvements, and had five patches during testing. Much of the testing during this initiative resulted in the changes added in the June 3 patch to the retail game.
The first patch's focus was on gathering server performance data after adding server improvements, as well as ensuring there were no issues that resulted from the changes. A significant addition in the patch was that the player tickrate was increased from 10Hz to 30Hz. As a result, a majority of players reported that engagements were much smoother and more accurate.
- Fix for explosion packs not being shootable sometimes
- Fix for reducing damage mismatch between client/server
- Fix for third person player orientation mismatch
- Character collision improvements
- Improvements for client side packet loss
- Various server performance improvements
- High Frequency/High Priority update (“Tickrate” improvements)
The second patch was used to check if the tickrate improvements were still working as intended. Due to some players experiencing increased packet loss from the higher tickrate, the High-Frequency Network Update option was added client-side, allowing players to lower it to their needs.
- High-Frequency Network Update client option
- Dampened explosive camera shake
- Possible fix for PC chat delay
- New maps: Operation Metro 2014, Wave Breaker (enabled later)
- Hainan Resort: Under-terrain exploit fix
- Other unmentioned small tweaks
The third patch of the initiative was focused on testing that the new FrameHistoryTime value of 1.0s for servers did not have a negative impact on the game and that the "Deathshield" bug, (which caused ragdolls of dead players to stop grenades and other projectiles), was completely fixed. Support for a competitive version of Obliteration called Obliteration Competitive was also added in the update, along with a fix for a jet altitude bug.
- Changed the FrameHistoryTime from 1.5s to 1.0s
- Deathshield fix
- Added support for the Obliteration small competitive mode
- Operation Metro 2014 exploit fix
- PC-Client stability improvement
- High Altitude Jet fix
Patch four was released to fix issues discovered in the testing of Obliteration Competitive, and to insure that the changes did not affect normal Obliteration.
- Added netcode high frequency kill switches to disable feature if server performance goes below a certain limit
- Changed the way FOV slider option works – the UI now correctly displays vertical FOV
- Improved the Uniform Soldier aiming based on CTE player feedback
- Added Jet 3P rear view camera
- Implemented FOV slider for vehicle 3P chase camera (option)
- Potential fix for Hardcore killcard not showing up properly
- Visual fix for weapon sticking out of ragdoll and rotating weirdly
- Save file location has been separated from BF4 folder
- Obliteration Competitive fixes
- Fixed an issue where on some maps players would be invulnerable
- Tweaked some map layouts
- Round won’t end if a bomb is planted and time has expired
The final patch of the initiative included fixes based off player feedback, and to insure they'd been addressed correctly.
- Jet rear-view camera on separate button (Free look)
- Russian Stealth jet ECM visual effect fix
- Uniform Soldier Aiming improvements (Based on CTE player feedback)
Following this patch, the majority of the changes tested during the initiative were implemented in the retail game on the June 3, 2014 update. A few changes were held back for further testing and could potentially be released as a future update.
Initiative #2: Core GameplayEdit
The second initiative launched was focused on Core Gameplay, referring primarily to "central pieces of the game" and how the game behaved with the netcode changes from the previous initiative.
The first phase of the initiative was focused on fixes/improvements for equipment and weapons that were to be shipped with Dragon's Teeth, as well as adding the bulk of the content from the expansion to insure that there were no issues with game stability. To stress-test this fully, all equipment was unlocked with the first patch for all players and the Ballistic Shield was added for use.
After a about a week of receiving feedback about the performance of the Ballistic Shield, a small second patch was released to tweak the Shield's abilities to better match the designer's intent for the gadget's use. Along with this, the remaining Dragon's Teeth weapons, (the DEagle .44, Unica 6, CS5, MPX, and Bulldog), were also added into the build for weapons testing. All equipment remained unlocked for all players.
- Shield bash damage, distance & spread tuned – no more one-hit kills.
- Shield incoming projectile damage improved. Single tank AP-round now kills.
- All Dragon’s Teeth weapons available for testing.
Initiative #3: CTE PrototypesEdit
The third initiative launched was focused on testing new features for the game, which were classified as "prototypes" as there was no guarantee they would be added to the retail version of the game.
The first patch for the initiative introduced two new "prototypes" for the players to test: improved Attack Helicopter flight physics and a fix for headglitching.
The improved attack helicopter physics allow them to be more maneuverable and capable of doing flips. The Z-10W was the first attack helicopter to have these physics applied to it, and it replaced the AH-1Z Viper on some of the maps in order to allow for players from both the US and Chinese factions to test it.
The headglitching fix applied in the patch made it so that bullets would come out of the barrel of the gun instead of coming from the player model's eyes, therefore stopping players from firing their guns while using certain types of cover. The guns that were tested with this feature at the time of the patch were the M1014, M40A5, M4, MG4, QBU-88, SCAR-H, DEagle .44, and the MPX.
- Collision fixes for Lumphini Garden, Pearl Market, Zavod 311, Rogue Transmission, Propaganda, Sunken Dragon, Flood Zone, Lancang Dam, Operation Métro, Hainan Resort, and Operation Locker.
- Improvements to the Kobra sight to make it look closer to what it was around the time the Fall patch was released while still being visible when facing snow.
- Corrected the Bulgarian and Estonian flags on their respective dog tags.
- Fixed bullet tracers showing through objects after hitting them.
- Implemented first pass of Squad Spawn 2.0, which makes it so that if a squad member is suppressed, the player cannot spawn on them.
- Added vehicle occupancy and vehicle information to spawn screen.
- Enabled PC gamepad assist for testing purposes.
- New soldier collision fixes.
- Changes to Obliteration Competitive.
The Community Test Environment had previously been announced to eventually be made available in Battlefield Hardline following release. On April 28, 2015 it was announced along with the 1.02 patch of the game that the CTE would be made available in May 2015. Functioning in a manner similar to the Battlefield 4 iteration, it was released on May 25, 2015, being made only available on PC.
