Iv had some ideas for new halo trilogys you might hait them you might like them.
Halo collonies trilogy: a trilogy showing the UNSC’s most powerful collonies fall prey to the covenant
Halo the great journy trilogy: a trilogy about the covenant part during the war
Halo spartans never die trilogy: a trilogy showing a different SPARTAN-II per level and there worst battle in the war starting with Samuel-034
Halo prepare to drop trilogy: a trilogy about ODST before and during the war
I like the spartan one better the covenant one I dont care about but I know some of the fans would want it.
