One of the biggest problems players had with Battlefield 2042 was the removal of several gameplay features that were present in previous Battlefield games. A Reddit user even compiled a enormous list of the “Core Features” and classic Battlefield elements not included in 2042. The list of missing features includes a lack of certain game modes, no class systems, no leaderboards, and no spectator modes just to name a few.

Interestingly enough, the lack of a single-player mode tops the list.
