A closed alpha for Battlefield V was held last month, giving a small group of people an opportunity to try an "early" version of the map Arctic Fjord. Developer DICE has now published an in-depth blog post in which it discussed the data and feedback it gathered from the alpha.

One of the main purposes of the alpha was to test Battlefield V's technical components, including its "many backend systems, player scoring rate, and many other things." Another area of focus was on the gameplay, and specifically, getting into matches. During the alpha, DICE ran into issues related to "matchmaking configuration" that resulted in error messages or players getting put into "less suitable server locations" that led to higher latency.
