There is an arsenal confirmed of handgun, shotgun, magnum, flamethrower and granade launcher. All the core elements of the classic RE games are present like the item boxes/safe rooms (safe room are confirmed to have the iconic save room music), puzzle solving - exploring/backtracking and so forth. Its the most RE game in the last ten years.
Only the kids who liked the action nosense of Re4-6 probably wont like it.
