Bloomberg has reported that Redfall developers at Arkane allegedly hoped the game would be canceled or rebooted.
In a report, Bloomberg states:
"Meanwhile, on September 21, 2020, Microsoft purchased ZeniMax for $7.5 billion.... the acquisition gave some staff at Arkane hope that Microsoft might cancel Redfall, or better yet, let them reboot it as a single-player game, according to sources familiar with the production. Instead, Microsoft maintained a hands-off approach. Aside from canceling a version of Redfall that has been planned for rival Sony Corp's PlayStation, Microsoft allowed ZenMax to continue operating as it had before."
According to the report, the reason behind Redfall's release as a multiplayer title was due to Zenimax saw the success of other 'Games-as-a-service' titles and wanted a piece of the profits.
"According to people familiar with the process, ZeniMax was strongly urging developers at its subsidiaries to implement microtransactions- that is, recurring opportunities within games for players to spend real money, say outfitting their characters. Although this wasn't an absolute mandate, several ZeniMax franchises such as Fallout, Doom, and Wolfenstein would soon release new versions incorporating online multiplayer and monetization options.
