Chris Redfield will star in Resident Evil 7's free Not a Hero story expansion this spring, though he won't look like you remember him. Capcom's promising a "short scenario" with a different flavour to Ethan's adventure – it's probably safe to assume that this will be a full-on first-person shooter like the latter stages of the main game's campaign.
Here's what the publisher had to say: "Who or what is [Chris Redfield] chasing? Find out soon in this separate story." An interesting comment for sure, we have some theories with regards to the answer but we can't post them here for fear of spoiling everything. We're looking forward to learning more in the weeks to come.
