Taken from Fun and Games group in GR.

Person 1 posts a sentence, and the next person has to develop this sentence - but using Fortunately/Unfortunately at the beginning of every new sentence.
You can choose what to use - Fortunately/Unfortunately - as you wish 

Example
Person 1: I went to a bookstore today
Person 2: Fortunately, there were lots of new books in there!
Person 3: Unfortunately, all of them belonged in a genre I hate
Person 4: Unfortunately, although I was open for new reading opportunities - they were all pretty cheesy
Person 5: Fortunately, I've just finished a lengthy, high-level classic piece of literature, I needed something light and stupid to balance it
Person 6: Fortunately, I saw all of them were on sale! 60% off, wow!
Person 7: Fortunately, I quickly found a book I might love so I bought it right away
Person 8: Unfortunately, my teacher just saw me holding my brand new copy of "teenage love" and gave me this weird look. Awkward!
[...]

and so on. Fun, right?

I'll start:

Fortunately,she owns an invisibility cloak that zombies weren't able to sense and see her.

Fortunately she was able to mask her smell by using perfume she found at an abandoned house.

Fortunately the zombies are all gone and she is  safe

Fortunately she found a lab with alive clone humans in tubes

fortunately all she has to do is break the tubes to rescue the alive human clones

Fortunately all the clones keep on replicating themselves 

unfortunately some are weird    and evil

Fortunately there are only 2 of them..one weird and one evil.

unfortunately the evil one has a mutation that give him magical powers

Fortunately a clone was set to be the defender of the other clones and has super powers too.

unfortunately she has no super powers to defend herself with 

Fortunately, she can share that super powers so she gave it to clones who can defend her.   

fortunately they fight the bad guys off and make it outside of the lab

Unfortunately, there were more bad guys waiting outside 

fortunately they still had their magical powers to defeat them
