Kickstarter update for ROAM speaks of "legal things" impacting the future of this zombie game, though they indicate this while this is preventing them from providing status reports about the project, it is not impeding development, and there does not seem to be a concern that this will prevent them from releasing the game when it's complete (thanks nin). This is confusing due to how vague it is, and this may not change, as they explain that how much they will be able disclose about this depends on how it turns out. Here's word:

Unfortunately, the situation of "legal things" is such that it cannot be revealed at the moment. Depending on the outcome of the aforementioned, we shall or shall not be able to disclose what has transpired. Whether full disclosure occurs or does not occur, the progress of game development has not been hindered, and will not be hindered. The lack of game development dialogue in updates indicates that it is hindered, as any logical individual would and should surmise. However, it is the "legal things" that are preventing us from providing game development dialogue. Please be rest assured that development is still occurring, albeit unable to be displayed to backers for now.
