Gears of War 3 Horde Mode: Defensive Items Cost

Gears of War 3's horde mode 2.0 features the ability to purchase defensive items to increase chance of survival against the enemy locust horde (And Lambent). Horde mode has a total of 50 waves, like Gears of War 2, however, there are now boss battles every 10 waves. The bosses you face will be random.

In between rounds, you will have 30 seconds to prepare for the next wave by creating defenses around the map. Making defenses, repairing existing ones, and upgrading is key to survive the locust horde and enemy lambent.

Here is a list of Gears of War 3 defenses and how much they cost to upgrade etc.



  • Level 1 Spike Strip Barrier - These are the weakest barriers, but still provide a decent defense during the lower levels. ($1000)
  • Level 2 Barbed Wire - More reinforced than the level one barrier and can take more damage. ($2500)
  • Level 3 Electrical Wire - Significantly stronger and is much better in the higher horde levels. ($4000)
  • Level 4 Laser Wire - This barrier can resist the most damage. These are very good to have on boss waves. ($5000)



  • Level 1 Cardboard cutout of Cole Train advertising a brand of cereal. ($500)
  • Level 2 No longer Cole Train, but a damaged mannequin. ($1000)
  • Level 3 A stronger red mannequin. ($1500)
  • Level 4 A boom box with scrap metal. ($2000)
  • Level 5 An Onyx solider that will fight for you ($????) ***only can upgrade if you have horde command pack***


Sentry Turret

  • Level 1 ($1500)
  • Level 2 ($3000)
  • Level 3 Sentry turret is effective for killing those berserkers . ($????) ***Only with horde command pack***

Sentry turrets are great to use in horde mode because you do not need a player to use them. They will automatically shoot the locust horde.



  • Level 1 Dual Turret using Retro Lancers. Not very effective for long range, but quite powerful. ($1500)
  • Level 2 Dual Turret using Lancers. More range than the level 1 turret and better accuracy. ($2500)
  • Level 3 Now a powerful Troika Turret. ($4000)
  • Level 4 An Upgraded Troika Turret ($5000)

I'm pretty sure there's a level 3 sentry turret upgrade. Haven't reached it yet, but after playing beast mode there seems to be a "stun" sentry.

How do you get the snetry turrets ?

Ben 5 years ago


You can aquire sentry turrets once you have level 3 decoys. From then on you can upgrade it 3 times (I belive), however it mabye 2 times according to numerous sources.

There obviously is an upgrade for the silver back considering it has a "experience" bar under it.

ChainGun Dragon 5 years ago

There was just a DLC which must have unlocked more levels for the Silverback seeming as how it says rockets are now available (at some level)

Hayden 5 years ago

The space next to the silverback... Who can tell me what that is...? It looks like a tv set (of course that's not what it is...) it appeared after I downloaded the DLC. Any help?

Hayden 5 years ago

Wait..... I did some gears-research.... I think it's an upgrade for the command post. But feel free to correct me if im wrong but that's my guess

That is what I am trying t figure out. I think it's the hammer of dawn support strike or something.

I have no idea how to unlock it, wish I knew.

I'm trying to upgrade the decoys & sentry turrets to use the new ones

How do I obtain the active reload? I was told to, and I quote, "Go to the 'Marketplace' to purchase the active reload." However, I cannot find this. I will never get this!

kyle 5 years ago

the new sentry is a fire bullet sentry it sets a berzerker on fire. just thought i'd let you know

Jkinnison 5 years ago

You get the rockets at level 3 for the silverback. It has an upgrade that cost $10,000. Once you upgrade it, you press A to mount the silverback and then fire with the RT button. You have 4 rockets in a clip that reloads right after.

mike 5 years ago

Anyone know how to level the turrett? It says I need 16k to next level. I put in over 40k and it only went down to 12. What part of repair moves that bar?

Yorgi Mashenkakov 5 years ago

How do you get active reload!?

sn4k3 5 years ago

has anyone beaten horde?

come on man 5 years ago

Are you that dependent on others? Active reload is pushing Ry bumper during reloading. The bullets will blink if done correctly. It will not count towards onyx medal unless you are in vs. Public private or ranked. Next time try reading ur instruction manual.

seriously guys? 5 years ago

u need to upgrade your manned turret levels in order to get the command post after purchasing dlc.
