DICE will be letting players get more involved in the development scene with their modern FPS Battlefield 4, offering a new opt-in Community Test Environment.
The public CTE will give the development studio a new test bed to throw out new ideas and solutions to current issues, and DICE already has plans for the first test. According to the blog announcement
, that will be netcode, which is what the player experiences with the game world including player-to-player interactions like damage registration. This involves tweaking to the “tickrate” servers and networking in general.
"By launching this new program, not only will we be able to address player feedback at an early stage, but also increase the overall quality of the game. We are excited to explore the possibilities together with you."
