There are lots of different multipliers as well in the Meta-Game scoring. The first one you will notice is the time multiplier which is shown below your score in the bottom right hand corner of the screen. The largest multiplier you can get for this is 3X multiplier and depending on the mission and the time you take to complete it it drops in 0.5X sections until it reaches 1X. Below are the time boundaries for each multiplier on each mission.

Sierra 117
3.0X = 00.00 – 15.00
2.5X = 15.01 – 20.00
2.0X = 20.01 – 25.00
1.5X = 25.01 – 30.00
1.0X = 30.01 +

Crow’s Nest
3.0X = 00.00 – 20.00
2.5X = 20.01 – 25.00

You also get a multiplier for achieving certain medals; the medals and their multipliers are:

Depending on the difficulty you are playing on there is a different multiplier. On Easy you get at 0.25X Multiplier meaning you only get a quarter of your score, Normal gives you a 1X Multiplier, Heroic 2X and Legendary 4X. It may be tempting to do it on Legendary for this Multiplier but it also counts for deaths and betrayals, not just kills.

The final thing you can get Multipliers for is for activating skulls. I therefore recommend that before you try to get the meta-game achievements to play through the campaign and collect all the skulls; by doing this you can activate any of the skulls you want and do the meta-game on any mission so you don’t have to do them in order. The skull multipliers are as followed:

All of the multipliers apart from the time multiplier are added within the mission so you dont always need to see the amount of points needed in your score box as long as you have a time multiplier.

The way I recommend you to get the meta-game achievements is to set up a second controller that is doing nothing. The purpose of this is in case you die you don’t go back to a checkpoint lose all the points you have earned and more for dying. If you don’t have a second controller ask a friend on XBOX Live to be AFK or be a cautious support player. If you don’t have Live either (why not it’s what make the XBOX the best) just be really cautious that you don’t die.

Play on Normal, you get 1X Multiplier and it is much harder for you to die due to reduced skill in the enemy AI and reduced damage dealt to you. Next activate the following skulls:

• Tough Luck – Spam and just aim grenades well
• Catch – Just dodge anything blue or spiky, which you should be doing anyway
• Famine – Just keep changing weapons and look out for supply drops
• Fog – Who needs a Radar in Campaign
• Thunderstorm – Higher rank = More points
• Grunt Birthday Party – Made headshots worth it and a good way of knowing you got a headshot
• IWHBYD – For fun
• Cowbell – With tough luck more explosiveness is good

With all these added you will get a 9X Multplier, I think didn’t check on Halo 3.

Because Thunderstorm is activated try to make your two weapons a plasma pistol and a Battle Rifle except on the flood missions. This is so you get easily take out Brutes with the Headshot EMP combo which gets you more points becuase of the medal multiplier and the fact they are a higher rank because of the Thunderstorm skull.

Good luck, doing these will get you well on the way to getting the original 1000g on Halo 3.
