This can be most difficult of all the Resident Evil; Revelations 2 ‘The Struggle’ levels but it can also be the easiest. If you don’t care about hunting, grabbing ammo, or finding new weapons, you can literally just run through the entire map to the end – allowing the globby zombies to see and chase you. Otherwise, you have to play a stealth game. You aren't allowed to be seen or do any other attacks than instant kills so you have to be more careful than ever. Being seen gives you 30 secs to get to the end of the map. There will be blood.
