Halo Studios reportedly worked on a Halo game that mixed battle royale and extraction shooter mechanics before the project was scrapped. The game, known internally as Project Ekur, apparently evolved from Project Tatanka, an earlier battle royale project connected to Halo Infinite. According to a report from HiddenXperia, Ekur would have had players dropping onto Zeta Halo, with the playable area gradually shrinking. Players could play as either a UNSC Spartan or, for the first time, a Banished Brute. The map would also feature AI-controlled Flood enemies that could infect areas of the map, while players fought rival squads and potentially teamed up to take down large bosses. The Flood storyline was intended to connect the game to a future Halo 7. Ekur was eventually abandoned as more developers were moved to help with Campaign Evolved.

Halo co-creator Marcus Lehto says leaving PvP multiplayer out of Halo: Campaign Evolved was a mistake. Lehto, who was the original art director for Halo: Combat Evolved, said split-screen multiplayer should have been included and mocked the decision on “lack of oversight and poor planning.” “Split screen MP in Campaign Evolved should have been included. There’s little excuse aside from lack of oversight and poor planning that led to this misstep. So sad this wasn’t included.” He later clarified that he was specifically talking about the remake not having PvP. “So sad this wasn’t included,” adding that it would be “awesome” if PvP were eventually added.
