Just a little hint in whats to come in Halo 4

Now we all know about Halo 4 having Masterchief and the Covanant back in the picture but what most don't know is that there will be more enemies than just the Covanant. Now these new enemies names are unknown for now but i will get back to you with them as soon as i can. Also to come are brand new maps such as; Adrift: A abandoned military base. Haven: Takes place in an unidentified structure. Longbow: A snowy landscape with lots of coverage. And many more maps to come.
