Exodus

The Devil His Due

You'll be badly hurt and on your own. You only have a simple magnum at the start of this mission, so you'll need to steal any firearm you can.

You'll start by fighting grunts, and many of them will resort to suicide bombing. Shoot them quickly to avoid being caught in their blast. With such low health, any heavy damage will instantly do you in. Meet up with the USNC to defend the remaining humans.

First heal up with a health pack. You'll team up with a unit of USNC soldiers. You'll be introduced to a new enemy, the brutes. These enemies are more durable, but not much strong than the elites you've encountered. The spiker they wield is a powerful weapon that will be useful in your Spartan hands.

You'll soon come to a jammed elevator. Brutes and grunts will storm from the left hand side. It's not required to actually save any of the residence, so concentrate on killing the Covenant. Either way you'll take the elevator, leaving any survivors behind.

Too Close to the Sun

You'll team up with a squad of ODST troopers. Grab a nearby jet pack power up and fly across the platforms ahead. You can split up on either side, though you'll have better protection taking the right path.

The enemy you'll want to take out right away is the brute carrying a gravity hammer. he can instantly kill your allies, which will put you at a grave disadvantage. Grenades are your best solution at destroying his shielding and taking him out.

Move ahead and you'll gain reinforcements for any fallen ODST members. enemy forces are a bit lighter in numbers, but the brutes will be armed with stronger weapons. Since you still have the jet pack, use your height advantage to get the drop on them quickly.

Once inside the next area, use your jet pack to fly to the top floor and leave through the exit. You'll gain a new unit of USNC soldiers. Lead the charge against the jackals and brutes. They are several floors above, so either toss a grenade or use your jet pack to fly onto their level.

The enemy is on the building's ground floor. To easily take them out, move to the upper levels and blast them with your rifle. If one does manage to get close, use your melee attack to quickly subdue them.

Outside are enemy turrets, your goal is to destroy them quickly. Use the pillars around the area to make your way behind them and neutralize the situation. Afterwards, a falcon will arrive and take you to your final objective.

There will be a warthog you can take towards the inactive cannons. This heavy firepower will be key in destroying the enemy wraiths. Move to the cannons themselves and start up the defenses.

There is a rocket launcher nearby, which will be great for taking out the remaining brutes. Finally, move up the building towards the last control panel. Pressing this button will finally conclude your mission goals.
