Unbreakable is the first chapter of the third act of Gears of War 3.


New enemies:

After crashing landing due to Myrrah, Hoffman has rescued you and taken you back to Anvil Gate. The fort is under heavy attack by enemy forces, so head to the front gate after stocking up on your weapons and supplies. Your starting point contains multiple Bolo Grenade spawns, Ammo stashes and two ammo closets (remember, these only hold one weapon in full mag) that have Hammerburst Assault Rifles and Longshots. Once you've picked your weapons, head to the front gate (two paths, lead to same destination, you don't need to pick). There are two Chain Guns outside. Use them, as the enemy will constantly come at you.

Hold off the enemies, which include Savage Grenadiers initially (and indefinitely). After a short while, Reavers and Grinders start appearing (these stop after a few moments). When the Siege Beasts arrive, it will destroy the front gate, and you need to move back. Failing to do so will result in the explosion and fire killing you. Falling back to the second gate, there are two Vulcan Cannons on both paths. Bloodmounts start coming in for a while, but the grenadiers are the most common enemy in this part. After holding off enough grenadiers, Maulers and Grinders start appearing again. Stop the Maulers before they reach the second gate. If you manage to hold the Maulers off (who come in waves of 4 at a time, sometimes with 2 Grinders), you will automatically proceed to the next chapter. If you don't, fall back to the third gate.

At the final gate, there are two more Chain Guns. Large numbers of grenadiers appear, and after a while, a stream of Boomers start coming from the gate. They will target the final gate to get in primarily. They will not target you until the gate has been demolished. Once the Boomers demolish the gate (although if you manage to prevent this, the next chapter will automatically start), defeat all enemy troops, until Bernie tells everyone she is going to drop the last resort, Hoffman tells everyone that the last resort is an Imulsion tank that you need to blow up, wait until the tank falls over the battlefield and shoot at it, blowing up all enemies around. Then a cutscene follows and you start the next chapter.


  • Anvil Gate plaque: Just as soon as you begin, turn around and it'll be on the wall.
  • Watercolor Painting: When moving toward the front gate via the right path, there will be a room on the right. The painting is hanging on the far wall.
  • Sam's Father's Medals: After collecting the Watercolor Painting, continue forward just a bit and you will be forced to cross the first courtyard. At the end of the crosswalk, look straight ahead to find 3 ammo crates. In between two of them in the corner you will find the medals.


  • Upon completing this chapter, you will unlock the "Anvil Gate's Last Resort" achievement.
