This game is unlike Resident Evil 5 but is more like Resident Evil Revelations. The goal is to get to the mastermind while taking down all kinds of zombies and an unrelenting boss, thanks now to the ability to move while you shoot, including side stepping and sliding underneeath for the first time. In this game, you get to do all kinds of things depending on which character you choose. The underlying goal if you have two people is essentially teamwork.
Not only that, there will be a lot of quick time events and driving sections. So be prepared as each scenario is different but at certain parts of the story, there will be a character connection that connects everyone's involvement. Last of all, you'll encounter puzzles that's either easy or a trial and error scenario. So the only advice is to always keep yourself on your toes.
