Reach IS an FPS, Reach IS a prequel, the beta IS coming out sometime in spring from ODST disk pre ordered or not, the game MIGHT come out in fall, a theory that sounds reasonable. Reach IS going to be using a new engine from the past games. There IS a trailer which most of you should have seen. THAT IS ALL WE KNOW PEOPLE! Everything else is speculation, theory, observations, and suggestions! PLEASE read this before you ask a question that I answered! If you do ask I have noticed that alot of people seem to think they know the answer because they read the book. THIS IS NOT A GOOD RESOURCE! All we know is the above and the community doesn't know anything else as fact!
