Dataminer Gosetsu has recently uncovered a reference to "Separate Ways", an extra game mode featured in the original Resident Evil 4, indicating the possible release of additional DLC for the remake in the near future.
According to Resident Evil Central, Gosetsu found a folder called "The Another Order" within the game's files, next to the files for the Chainsaw demo and the Mercenaries mode, which is launching on April 7. "The Another Order" was the Japanese name for the "Separate Ways" game mode.
The "Separate Ways" mode is not present in Resident Evil 4 Remake, but the above implies that it could be featured in a future DLC. Moreover, there is a moment in the game where Leon tells Ada they need to go their "separate ways", which appears to be a subtle hint towards the possible inclusion of the game mode.
