I'd like to see the story get to a whole new level like it was in halo 3 where the chief kept getting that image of cortana in his visor maybe he gets that in halo 5 and at the beggining like halo 2 testing out look and new gadgets etc... he then should get aquainted with his fellow spartan 2's because that would be awesome considering they played big roles in the books plus i'd like that whole cortana on his mind plus a new galaxy to explore or world of some kind where its all about the flood and how they need to achieve better gear if I remember type 12 or something and chief and his spartan friends run into flood plus covenant play a role kindof mixed relationship arbiter and chief friends etc... and somehow involve prometheans because you can't scrap those considering they played a big part in halo 4 maybe they find another shield world that leads to more worlds that has flood and they get the coordinates arbiter comes to help maybe there are some ships that don't want to help so you're on that world with your spartan friends thinking about cortana while killing flood trying to find that type 12 gear that 343 spark talked about and there is a covenant v covenant battle going on and the only apperance of prometheans sadly will be on shield world or you could add some phony way to control them because they are ai's so maybe they come to help fight the flood something to this degree would really be good and for a ending maybe arbiter sacrifices himself to save chief and they get back to infinity and bomb the world I don't know but something good like when halo reach you kept losing the spartan 3's and for the ending you sacrificed yourself to save the ship because this ending was dramatic and shows that because he did that the chief blew up those halos etc... just don't make everyone too invinsible but I wouldn't want chiefs whole entire team to get wiped 1 or 2 within the story always adds to it especially if they died for a good cause doesnt have to be his team though it could be just about anyone but it's hard to say anything at this point because they got quite a few ways of making the story awesome this is something I think would be epic but you can always worktouch it quite a bit also if i'm incorrect or anything i'd love to get reviews on these ideas of mine I managed to get croped into my head in the 10-20 minutes I took to write this and as for online i'd do the same old thing in halo 4 with new weapons obviously add in classics like smg and dual wield and more stuff like new vehicles and weapons but I think the BEST idea i've got so far is spartan 2, spartan 3 and spartan 4 armor all in multiplayer and add the elites back because those were classic and maybe we can get a crack at some more foreunner weapons and experiemental unsc stuff and some more covenant junk and flood weapons sounds cool don't know how that would play out.... the sky is the limit 343
