Right Ive covered the enemy”s now for the skulls. Each skull has its own Multiplier Value that adds to you point out come more skulls activated = more points (Silver skulls don”t give points there just for fun)

(Format layout

Picture/Name

Effect Information/Multiplier Value

My Views)

Skulls
Iron
Co-op reverts to previous checkpoint on player death. Solo restarts mission.Multiplier 3.0X

this is a pain but with 3X the points its still not worth it

Blackeye
Shields don”t recharge except from melee attacking enemies.Multiplier 1.5X

this is fun but i don”t recommend it unless you think you some big tuff hero type

Tough Luck
Enemies always make every saving throw, always berserk, always dive, never flee…Multiplier 1.5X

this is fun to have on because you have to try and aim plus its easy points

Catch
Enemies are grenade happy.Multiplier 1.5X

Simple more grenades = more grenades dropped = more kills for you easy points

Fog
You do not have a motion sensor.Multiplier 1.5X

you have eyes so do you really need a motion sensor if you don”t this is easy points

Famine
Weapons drop 50% less ammo.Multiplier 2.0X

this adds skill to the game and with a nice multiplier i recommend you have this one turn on

Thunderstorm
Major upgrade to all enemies.Multiplier 1.5X

makes them harder to kill good fun really and easy points

Tilt
Damage is modified.Multiplier 2.0X

this is a pain makes them immune to what they where resistant to so i don”t recommend you turn this thing on

Mythic
Double enemy health.Multiplier 2.0X

gives them double health making them harder to kill but still easy points if you have it on

Blind
HUD and first person arms and weapon are hidden.Multiplier 0.0X

this is worse then fog you wont see anything your shield, weapons ammo, Grenade count don”t recommend you have on at all

Cowbell

Acceleration scale from explosions is increased.Multiplier 0.0X

makes explosions bigger for them not you this ones up too you

Grunt Birthday Party
Grunts explode like piñatas if they are killed with a headshot.Multiplier 0.0X

this is a laugh have it on just for fun

I Would Have Been Your Daddy
You’ll hear things you never knew existed.Multiplier 0.0X

this is a laugh just listen to some of the things said i recommend you have it on just for fun.

Right Ive done the enemy”s and the skulls now for the levels. Now each level you need a different amount off points in which is based on level size and amount of enemy”s in the level.Now you can get points in the level by killing enemy”s and beating it under a set time or difficulty.

This is how the point multiplier is effected by difficulties.

Easy 0.25X

Normal 1.0X

Heroic 2.0X

Legendary 4.0X

So if you kill a grunt on normal you get 10 points but if you kill it on legendary you get 40 point which is a big difference

Now time effects the out come too if you complete it faster you get more points the multiplier starts off with 3.0X and goes down look

Start 3.0X

2.5X

2.0X

1.5X

Finish 1.0X (which is zero time bonus).

(if you start from any check point you start with a 1.0X multiplier)

The quicker you finish the more points you get but some times quicker isn”t better
Now below i have put the level and the amount of points you need per level to get the achievement as well as the time multiplier decreastion rate times.

Right now thats get down to scoring with style It’s not just enough to shoot, Beatdown and Assassinate a enemy. You have to do it with style to get the big points. All style-based multipliers will get you a nice 1.25X increased point multiplier when you get a kill.
Here are all of different killing styles that will earn bonus points during your quest to Finish The Fight!!!:

Style Factors
Grenade Stick
Stick an enemy with a plasma or brute spike grenade to get a 1.25X point bonus. So remember that grunt i mentioned earlier, who is worth 10 points for killing on Normal, well he would actually get you around 12.5 – 15 points if you stuck him with a plasma or brute spike grenade in the same level.

Headshot
Take your time and aim well and you will get rewarded for it. All enemies will give you a more points if you kill them with a headshot instead of just shooting like the shots don”t count instead aim and make them count!. Headshots will give you a 1.25X multiplier to the point value for any enemy killed with a headshot.

Stealth Kill
Sneak up and attack an enemy from behind to earn a Stealth medal as well as a 1.25X point multiplier for the killed enemy.


Road Kill
Splatter the enemy and you will get 1.25X on top of the points you’d normally get for just shooting them to death.


Multi-Kill
Killing a 3+ enemies in a row will give you a bonus point multiplier. A multi-kill is stated as killing at least 3 enemies within 1.5 seconds of each other. Successfully doing this will get you 1.25X on top of the normal points you would get for killing each enemy group.

Needler-Superdetonation
The Needler finally becomes the “Noob” weapon Bungie wanted it to be in Halo 3. If you can get around 8 – 10 needles into an enemy ,You will get the “superdetonation” which explodes and sends their dead body flying. Doing this will get you a 1.25X point multiplier.

“EMP”
Halo 2 veterans should remember the “noob combo” right? if not a “noob combo” was using a plasma pistol full charged to drop a enemy”s shields and then to switch to a BR get a headshot for instant kill. You can use this against the Brutes throughout the campaign and it’s Very useful!!!. If you hit an enemy with a charged plasma pistol and then get the finishing shot off within around 3 seconds you’ll get a 1.25X point bonus.
Now i have two things left to cover one is

Penalty Points

If you die (which could happen a lot depending on which difficulty setting you have it on and skull settings) you will LOSE points!!!!. The base penalty for dying is -25 points for each death. This value will get increased based on your difficulty setting. So every time you die when playing Legendary will cost you 100 points. If you betray one of your teammates you will also get a point penalty. The baseline value on Normal for a betrayal is -50 points. So please watch where you are shooting guy and girls.

Now for the last thing

My Recommendations

Now the best way to do this for the achievements is on normal in Co-op with one other player and setting the scoring to Free For All so you know what you are scoring. Now heres the good part turning on some skull”s i had these skull”s on Tough Luck, Catch, Fog, Famine, Thunderstorm and Mythic for points and Grunts Birthday Party and IWHBYD for laughs. Now start up the match and the person who”s going for the achievement does all the work while the other guy stays back and Be the respawn point. Don”t worry about time just go for kills with them skulls on i managed to get double the amount of points each level needed and bagged myself the achievements. well i hope this helps and good luck guys and girls
