ATTENTION MOD USERS: THIS OPTIONAL UPDATE WILL DISABLE YOUR MODS WHILE ACTIVE!
This is to ensure that the new features can properly be tested. If you have previously opted-in, you must opt-out of the beta via Steam to continue using mods.
Phew, with that out of the way… the Survival Mode beta has launched! There is a lot of exciting stuff to take in here: the wellness system (which simulates hunger, thirst, and exhaustion), all new illnesses and antibiotics, crippled and broken limbs, and a long list of other

As a big fan of the New Vegas Survival Mode and an even bigger fan of Skyrim's survival mods such as Frostfall and iNeed, I'm really excited about these additions. I think they'll add the desperate yet rewarding post-apocalyptic feeling that I felt was slightly missing after New Vegas. Bethesda even mentions four tenets of design regarding the new features: Strategy, Exploration, Resource Management, and Role Playing. Nice.
Sure, it'll likely be more difficult but as they say, nothing good ever comes easy. As one of the developers noted:
“My routine is completely different this time around. Sanctuary is my sanctuary. Each day I venture out in search of supplies, and I return home with stuff. I take it one day at time. I need to live.”

Sounds awesome! So if you're ready (remember, this update will disable modding while opted-in), give it a try and be sure to provide feedback to Bethesda. After all, it is a beta test and I'm sure your input will be invaluable. For the full story, head-over to the the official Bethesda Blog.
Good luck, out there!
