Pros:

-You're all alone!!!
-Much like Last Man on Earth, but without any specials
-Much more common infected.
-Open door... Horde waiting on other side
-Start with pills

Cons:

None

Conclusion:

Amazing Mutation!
I actually found this difficult but fun to play on hard mode.
Piece of advice to players, don't have a magnum and a shotgun at the same time. You'll get horded easily. :P
As a let's player, I will definitely make a series from this mutation.
