Most people think ODST sucks because of no Matchmaking. But guess what, ODST was just a expansion pack for Halo 3. (Its called HALO 3: ODST) So matchmaking was on Halo 3. And besides, thats where firefight already took place of Matchmaking. Besides, I think the game is pretty darn good for givin' me 100G for just finishing the campaign on normal :).
And the game took place during halo 3. Its basically just showing what the ODST's(excluding the ones that ran off to be with John Spartan) were dealing with as what John Spartan was.
So now you see, its not so bad ou need health packs to gain health, because in real life you could not regen health silly gooses!
So now you see, this was just a expansion pack, so stop saying this was the worst Halo ever. At least Bungie makes games for us, Let me see you make a video game.
