The Survival Update, as its name suggests, is not DLC, but an update to the game itself.
Mac Compatibility
Up until the update to the Steam SDK in July, the way Big Picture worked meant we were unable to offer a Mac version, but that's all changed now.
Sorry to keep all the Mac owners waiting, but it's finally here.
Price Change
Back in 1995 is currently $7.99 as part of the Degica Sale this week,
but once this is finished, we'll be changing the price to $9.99.
English Voices
Voices have been added to the in-game cut scenes.
Additional Hard Mode + Overall Rebalancing
Ichijo-san reviewed and changed the fixed animation frames for the player character and hit detection, which is why this is no longer just an added mode, but an update to the entire game.
This is why that while system data is backwards compatible, save data is not. So even those of you who finished the game in a previous version will be playing from the beginning again.
New location, enemies and puzzles
This update contains a new location: "The Factory". There are some new puzzles and some existing stages also have additional locations. However, there are no achievements.
Updated Controller Support
Added compatibility for a lot more controllers and changed the game to handle full controller support too. Hopefully, this will also fix many of the controller-related issues some of you were experiencing.
Other Items
Improved various elements including camera work, effects, the scenario etc.
Hope you all enjoy the update!
