personally i hope she doesnt come back because by her death chief has turned into a better human not just a machine and if shes back he will just turn back into a machine following orders not having an self opinion
my idea would be to be able to have space battles so you can control ships and make different ship classes and just have wars on that and your base would be a refueling stationg which you can upgrade and add defences and supplie pads ect
i hope they do make one , i love halo wars because its a fun game and adds another story to the halo saga so making a number 2 would be good because it would add another story to the game
