I have a strong feeling that I've seen this game here before, but looking for it didn't yield any results, so if this is a repost, please tell me.
Mutant Uprising is like reading a book where the different pages are chapters that you write yourself with a nice picture behind it. In black and white. It has a few comical moments unlike Dead Frontier: Outbreak, and you play it by reading what the current situation is and then choosing from different options what you should do next. The basic concept is pretty much the same: Avoid zombies, kill zombies, survive encounter with zombies, end game and see your rank. It has a few different choices where it spares your life so it's not just a trial-and-error thing where you have to choose one right option or you die. Generally you still follow along the same path though, so it's a bit linear. You can collect items along the way as well, but there are only 3. These give you new options in certain situations.
In my personal opinion, I'm finding it quite fun. The jokes are entertaining and it's definitely made by someone who's experienced with the Internet, making it much more entertaining when you are too. You can do acts of kindness and brutality which I think is a great addition, as it makes you feel like you're shaping the protagonist's personality.
Also there is a part where the protagonist can scream "You are my bitch!" while bashing someone's brains out, rubbing them all over his face and roaring in triumph, so you know you want to.
