This game requires a constant internet connection for all game modes.

Command & Conquer 4: Tiberian Twilight is a real-time tactics game in the Command & Conquer series, serving as the final game in the Tiberium universe. It requires an EA account and an active online connection to the official servers at all times, even when playing the singleplayer campaign or skirmishes against AI. Like in Command & Conquer: Red Alert 3, the campaign can be played in co-operative mode with a second human player, but this time solo play does not force an AI co-commander. Units are unlocked by leveling the player account through free-to-grind methods, but do not offer paid boosts of any kind. The maximum player count is increased from 8 to 10.

The game was initially supposed to be a multiplayer-only spin-off of Command & Conquer 3: Tiberium Wars for the Asian market, named Command & Conquer: Arena, but during the prototyping phase, internal corporate meddling resulted in the game receiving a full campaign and shipped quickly, despite the decision being poorly received by the developers.[1]

The game was panned by critics and fans alike due to gameplay design and storyline decisions, finding itself on lists of worst-rated mainstream games on Steam.[2]

Post-launch support included 3 minor patches tackling installation issues in non-English languages, network stability and map additions, but the gameplay itself was never tweaked beyond the release version. A map editor (Worldbuilder) was also released post-launch. EA Los Angeles reorganized by splitting to Danger Close (FPS division) and Victory Games (short-lived RTS division) shortly after the game was released.

The game suffers from extended server downtimes, which affects multiplayer viability but permits campaign playthroughs. It was delisted from Steam on October 12, 2021[3], but remains available as part of the Command & Conquer: The Ultimate Collection package on Origin/EA App. It is one of the few games in the series without an alternative community server.
