I owned halo 2 halo 3 and odst . I hated halo so bad and thought it was a overrated peice of s h i t but after playing odst i love the halo storyline . ODST made me a halo fan . All annoying things from old halos like the music and the gay main character master cheif were taken away by the awesome humanish less sci fi story of odst with its cool music and 34 levels in total ( 10 firefight ,21 halo 3, and 3 halo mythic disk) But since i hated the others i didnt pay attenttion to the story , but being intrested in odst i beat it 4 times, found all audiophiles and , saw legendary ending . It combines with halo 3 story so i wondered why the covenent want to find the ark which must be near new Mombasa . And why they need the engineer to do it .I also want gamertags for fire fight
