Out of the Ashes is the 18th mission of Crysis 2. For this walkthrough, players will control a tank, and then navigate a number of Ceth-infested buildings in order to get to Central Park. The mission is quite fun as you will get to move across the skyline of the city and jump across rooftops.

1. Go towards Tara and Gould. Jump up to get to them.
2. Get inside the tank. You will control its cannon.
3. Note: keep in mind you also have an alternate rocket attack with the right mouse button.
4. Start taking out any aliens you see when the mission is updated.
5. Focus down the Ceth Mech. It will be highlighted with red.
6. When the tank crashes, ammo up in the spot just ahead of you. Continue on foot to the objective.
7. Enter the building. It's easier to just run through here instead of killing the aliens. 
8. Use the elevator.
9. Go around the blocked doorway. 
10. The area ahead will be crawling with aliens. Jump up onto the metal ledge at the objective point, clear out the Ceth that are right next to you, and open your visor with B. Mark the alien ship inside visor mode, by pressing F when looking over the alien Gunship.
11. Clear out the rest of the Ceth in the room.
12. drop down into the lower floor, jump into the nearby building and go up the stairs to the left.
13. Drop down onto the roof below from the opening in the wall. Pick up the ammo/weapons.
14. Jump to the next roof. It will be crawling with aliens. It's much to just spring past everything here, as you can get overwhelmed easily.
15. Run past the Tank. Wait for a mission update (which will make the building below collapse and crash on the building you're on). Jump down to the next roof in Armor mode, just behind where the Tank appears.
16. Watch as suggested by the game tips and wait for the mission to end.
