This game is currently in the Concept Phase which means it is getting designed and developed. You cannot preview it until later. First Out will start off as a single player game but might turn into a mult-player game depending on it's popularity.
First Out is a recreational park where there are many levels. You compete with other participants in a time trial. For example, in one level you have to jump a deep lake. The next levels will see you jumping multiple times with tiles that fall etc. So there will be many levels having different obstacles and challenges.
Like the slogan goes... Be the first out.
