When you can phrase your question properley I'll awnser it!
well what you do is beat all levels on halo 3 then you get the cool armor
Chieftains are one all the levels except floodgate, Cortana, and Halo.
In the first game's campaign, Halo: Combat Evolved, there are 10 levels. These include: "The Pillar of Autumn', "Halo", "Truth and Reconciliation", "The Silent Cartographer", "Assault on the Control Room", "343 Guilty Spark", "The Library", "Two Betrayals", "Keyes", and "The Maw".For a complete list of all levels, multiplayer and campaign, of all the halo games, visit:http://halo.wikia.com/wiki/List_of_Halo_Levels
To finish Halo, you have to successful go through all the hurdles and levels. The user manual has all the tricks on how one can go through all the hurdles.
you hav 2 complete the game
I think so, you just have more multiplayer maps and games, and you have all the levels instead of the first one.
you have to beat it on all difficulty levels and obtain every hidden skull in the game.
I actually think MW3 is better. First of all its newer and I think it has better graphics than Halo Reach. Second,MW3 has more levels in campaign and a whole lot more levels in survival. (compared to Halo Reach's firefights)
It's a first person shooter based in the future. Main plot idea is that you are a spartan; a marine with a futuristic suit, and there is 2 main alien armies threatening earth.REMEMBER: HALO!halo is awesome, halo is cool, halo is fun, halo is tricky, halo is all skills, halo is strange, halo is customizable, halo is clever, halo is K.O, halo is different, halo is award winning, halo is recommended, halo is levels, halo is master chief, halo is online, halo is known, halo is different, halo is challenging, but most of allHALO IS LEGEND!!!!!!!
I am pretty sure over twenty levels unless one level equals all of the night then like 4 :P
you can only create halo 3 levels on forge, which arent really levels at all
Just beat all the levels on normal difficulty
