GENERAL
This mission is actually very simple to get par score on. It takes a few skulls and no rushing for par time. I played this level on Heroic with the following skulls and achieved a respectable score of 30k.

SKULLS
Catch - Enemies throw more grenades. Alot of grenades will be thrown so watch out.
Famine - Weapons dropped have half ammo. After the first room against the brutes, there is alot of ammo crates, ranging from Carbines, Beam Rifles, and Swords.
Fog - Disables Radar
Jacked - Can only enter ground vehicles by boarding. No vehicles on this level
That's Just... Wrong - Enemies become more aware.

WEAPONS
Personally I found this level easy carrying a Beam Rifle to lower the shields of elites and to kill jackal snipers from a distance. The other weapon I carried was a Carbine, ammo is plentiful after the first area and can be used to dispatch every enemy. Try to only use plasma grenades on unaware enemies, or from a distance, as they will rush toward you when you stick them.

MINI WALKTHROUGH
Since the whole mission is pretty straight forward with these weapons I will be describing how to get through the first room you spawn in.

You will start off on a platform with two brutes shooting you, while backing up away from them you will want to take one out with the needler you spawn with, which will make the other one go berserk. Pick up the dead brute's plasma rifle and take out the grunts while avoiding the brute. By this point you should have a few plasma grenades, which you can use to stick the final brute.

The next few waves are 2 brutes and 4-6 grunts, you basically want to do the same thing as before, but this time you will want to take cover behind the huge columns at one end of the room. You will eventually kill brutes with carbines and will want to replace your brute plasma rifle with the carbine. Now you can take out the grunts with ease and depending on your ammo can quickly take out the brutes as well.

TIPS
From here on out its a cake walk (as much as it can be). Focus on killing every enemy that you come across, try not to backtrack that much, and take your time and stay back. Also, when you see enemies fighting eachother, try your best to take out the guys as they become one shot, especially the elites as they offer a good amount of points. As long as you have 26k or so by the time you hit 50 minutes your good to go. Try to limit deaths, dont restart from checkpoint since it deducts points, and only backtrack if you need ammo, if you miss an enemy or two you will be fine. I finished the level in 42 minutes (1x Multiplier) and had 28k going into the final room. Good luck!

I recent update has lowered the score necessary for many levels. As such, this level is now ridiculously easy to get par score on.
The new par score is 11k, and I was able to get 14k just by speed-running the level on normal. Feel free to put on the Jacked skull for a point boost, but I didn't use it.

The only areas where you actually have to fight enemies are
- The beginning
-- You have to fight the initial group, another group that comes out a door, two brutes that come up the elevator, and one on the balcony.

- The first grav lift
-- There are several enemies before the lift, as well as a brute and I think 4 grunts that come up the lift

- Saving the marines
-- You have to kill most if not all the enemies in the room before and after you save the marines. You can camp the lifts for most of them.

- The ending
-- The room starts with several brutes, three ultra elites, and a few hunters that run in soon after. You have to kill all these enemies to proceed.

I ignored just about every other enemy during the run. I kept a sword on me at all times and only really fought if there were too many people to run by, or if my sword lunge gave me a boost forward.
The only group I had to fight other than the ones listed was the group that comes out on the bridge, right before the final room.

I didn't have a clean run by any measure of the word, so getting par time on normal should be enough to get you the par score.
