The Dead Ship is a Remix & Continue Story that differs far from others. There are lots of limits, for example: You can only take 3 hits at the moment, however some enemies can deal more than just 1. Some enemies can blend in with the environment, Stun you, and have the potential to one shot you. Some rooms are VERY dark, requiring a light source. The biggest trouble is an ammo count for ranged weaponry. That is, unless it uses mana or is a melee weapon.
The reason Demon RoO is here is to collect data on what happened to the ship. All the researchers here have become infected entities, with no way to cure them, which means ya gotta kill them. You can also get shards from killing enemies, which can be used on the nearby shops for ammo and such. WARNING: This is not for those who are afraid of disturbing creatures or sudden noises. Remix only if you are not afraid of these 2 things.
