The Resident Evil 7 demo, which is currently available to download on PlayStation 4 for PS Plus members, isn't going to be a part of the released game.
Capcom told Eurogamer that the full game will feature a different lead character than the man in the demo, so don't get too attached to him. Meanwhile, players have found an axe - and attack buttons - so it looks like there will be actual combat in the full game.
The Resident Evil 7 demo is now available to download from the PlayStation Store. It should keep you occupied for a little while, as there are multiple endings to discover.
