I'm not sure if the series is finished or not (having just played the 4th installment I think it is, but time will tell), but I thought it's time I mentioned it here.
Usually when I see anything that has something to do with zombies uprising, I usually steer clear away from it. I dunno, I just don't like the genre so much, and it's been done to the death anyway. So I'm not sure what kept me interesting with this series. Perhaps it's the comics style visuals?
Maybe the nice build-your-own-adventure interface with clever rewinds when you die? Maybe the dialogues? Maybe the character build-up at the breaks between fights? Maybe the bluegrass songs played throughout the series? Or perhaps the series comes from the prolific creator of Alice is dead and Hood? Probably a bit of all of the above.
Each episode takes only a few minutes to play, or if you want to be thorough and try all story arcs probably a bit longer, so it can't be that bad, right?
