No Halo 1.5Xboxgamers did alittle interview thingy with Matt that works at Bungie. In that interview Nick from Xboxgamers.com was confirmed that there will be no Halo 1.5 . As all will know we were all looking foward to having this game, but now we won't as Halo 1.5 won't be developed for Xbox. Thank you Xboxgamers.
But just look at it on the bright side, that doesn't mean that Bungie will stop making Halo games. We all can look foward to Halo 2 and maybe Halo 3 and 4. So we will be getting a new Halo game or games but it just won't be Halo 1.5 .
