Having played Battleheart Legacy($4.99/Universal for iPhone and iPad) for nearly a month now, let me share some of the tips and tricks I learned.
For a more extensive walkthrough, there are plenty of excellent and in-depth resources out there, such as in the Touch Arcade forum, but I hope my own experience will help you out as a starting player. (Check out the review/guide to Battleheart Legacy on appSIZED here)
For kids of my generation, Ghostbusters is an important part of growing up. You have these four funny guys (Egon, Peter, Winston and Ray) banding together to rid the city of ghosts, the scientific way. I learned about ectoplasm and the ways of Slimer, and my sisters and I named our very first hamsters after Egon and Jeanine (the wisecracking secretary).
To give you an idea of what Ghostbusters is about, check out the movie trailer below:
A cartoon series and several movies and later, Ghostbusters is all but forgotten. Not to us who grew up watching them, and not to XMG Studio whose developers have come up with a way to keep the Ghostbusters alive through Ghostbusters Paranormal Blast.
