The upcoming remake of Halo: Combat Evolved, titled Halo: Campaign Evolved, is slated for release on July 28. Players looking to gauge their time commitment can anticipate a first playthrough lasting between 8 and 12 hours, according to developer estimates based on experiences with the original game. This timeframe can vary depending on the chosen difficulty setting and a player's familiarity with the Halo series.
The remake will introduce three new prequel missions collectively known as Operation Meteorite, though their specific titles and content remain undisclosed. These new missions will supplement the original ten missions from Halo: Combat Evolved. The original campaign's missions included The Pillar of Autumn, Halo, Truth and Reconciliation, The Silent Cartographer, Assault on the Control Room, 343 Guilty Spark, The Library, Two Betrayals, Keyes, and The Maw.
For those aiming for complete eradication of in-game challenges, including the collection of all Skulls and the attainment of every achievement and trophy, the total playtime is estimated to extend to 15-20 hours. This extended duration accounts for the inclusion of new Skulls, which will require dedicated exploration and may not be easily discoverable using prior game knowledge.
Halo: Campaign Evolved will feature these additions and reworked sections on top of the original gameplay experience. Players preparing for the launch may also want to consider the game's cross-play and cross-save functionality.
