I dont see any jet packs or spin fusors or power armour or skiing or any other tribes-like stuff in halo. But hey if you say so, i have not played tribes 1 so i might be missing something. But AFAIK tribes has no story line except that it is in the starsiege universe and tribes 3's single player campaign is QUITE a bit newer than halo.... Not that i am defending halo but please explain cause i dont see how, (i actually DO want to know).
