We are working hard to try to ensure that Broken Sword 5 - the Serpent's Curse: Episode 2 on iOS / Android will be released later this month. However, we have to allow for unforeseen delays, which are part of the game development process. We are delighted that there is so much anticipation!
We have determined that the best solution is for iOS Part 2 to be an in-app purchase, provided via a software update to the Episode 1 App. On Android, Episode 2 will be an entirely separate paid App. We hope this clarifies the situation, and our sincere apologies for any confusion this may have caused.
