How to unlock the Stock Piled achievement in Gears of War 3 - Definitive Guide

IMPORTANT: If you meet the retail requirements already, then this achievement will pop upon acquiring the Forces of Nature DLC and exiting any match, be it Horde or vs. multiplayer.

Peter Knepley, Senior Multiplayer Programmer at EPIC Games, responded via Twitter to a question about the fortification levels:

External image


Maximum Fortification levels (at retail):
Barriers- Level 8 ($170,000 total investment)
Decoys- Level 7 ($170,000 total investment)
Turrets- Level 8 ($360,000 total investment)
Sentries- Level 6 ($135,000 total investment)
Silverback- Level 2 ($200,000 total investment)

You level up your fortifications by spending money building/repairing/upgrading them. To determine how much the money you spend actually counts towards leveling up your fortifications, use the following formula:

Money towards fortification levels = (Money Spent) x (Difficulty Factor) x (1.0 + Mutator 1 + Mutator 2 + Mutator 3)

Difficulty Factors:
Casual = 60% = 0.60
Normal = 80% = 0.80
Hardcore = 100% = 1.00
Insane = 110% = 1.10

For a quick way to level up your fortifications, I suggest playing on Hardcore or Insane difficulty with Super Reload, No Ammo Pickups and Friendly Fire. Start at wave 39 on a map with a good funnel point for enemies- I prefer Trenches (behind sandbags in nest area) or Clocktower (behind the angled wall near a decoy close to the initial spawn). DO NOT FINISH THE WAVE- intentionally die to the final enemy, restart at current wave, spend your cash during the 30 second countdown, and repeat. Friendly Fire is to damage the Silverback so you can spend money on it.

Per Hotdogmcgee:
It's faster to level up via this method for everything except the silverback.

2 controllers, Insane, Friendly Fire + 2 other +10% mutators, doesn't matter which. I prefer Mercy, as you can have command posts with multiple decoys/sentries.
Before buying the Command Post, player 2 gives player 1 his money. Buy command post, sink the 2k into whatever needs leveled up. Smoke tag each other and restart from beginning. With a good rhythm, you can knock out a wave in 30-45 seconds, with re-loading, still easily under a minute per.
2000 * 1.1(insane)*1.25(mutators) = $2750 invested/minute, or 165k/hour.

Saves the trouble of messing around with a full wave of enemies, and you can do it by yourself so you don't have to split the winnings. This is also how I ground out my founder ribbons, since you get one every time too.
As always, if you feel this solution deserves a thumbs down, please explain why so I can make any necessary improvements. Thanks!

This is a pretty comprehensive guide. I just wish I had these mutators unlocked so I could make full use of my cash. :P

Trenches is pretty much impossible on Insane, played for an hour and never got the wave down to 1 enemy, I think on average I killed 5-10 before I died.

Going to try Clocktower later, might try wave 29 on insane, or move down to hardcore

Instead of insane why not just play normal with 3 10% hard mutators?

MFC, you need to choose restart from the beginning instead of retry wave to get the founder ribbon everytime

Leveled my turrets all the way to 8 before realizing I had to start from the beginning instead of the wave. SHOOT!

I'm confused. Why this achievement won't unlock if I met its requirements? Why do I have to pay another DLC just to get this achievement? My silverback is sitting somewhere in level 3 and the rest are maxed out. Thus meeting requirements and this isn't unlocked.
I have Raam's Shadow and Hoarde Command Pack DLC, but not Forces of Nature or Fenix Rising. so I'm confused by the term 'retail'

You need the Forces of Nature DLC to unlock this.
Silverback at retail had a max of level 2. Horde Pack increased it to 5. You only need level 2 for this achievement, meaning you can get it with the Forces of Nature DLC but without the Horde Command Pack DLC.

Wait, the Mutators add to how much cash spent on fortifications adds up?

No wonder the numbers just aren't adding up, there was no way I was getting 110% on Insane.

I've wasted so many hours....

Anyone know the best map for each fortification? Like a base with 2 decoy's

I've been doing this on Mercy. I build the post inside the church for the 4 spikes and decoy while working on unlocking the infinite ammo mutator (Work on 5 fortifications in a round 100 times). For the dual decoys, use the area across from the church. I found it to be smarter to do 1 decoy and a turret since the turret will be 1,500$ and I'll have 500$ left over. I haven't got to them yet, but I'll use the cliff-side command post for the dual sentry turrets. The cliff-side post is also a good place to get a turret and decoy built. I usually just go to whichever one I spawn closest to.

Do you need level 7 or 8 for the decoys.

good guide but if playing solo definitely better doing it on hardcore since overtime playing on insane you'll get lazier and waiting 30 seconds for another wave after only getting a few kills will get annoying

READ THIS BEFORE ATTEMPTING TO BOOST FORTIFICATIONS!

Do not change the options for Weapon Tutorials or Tooltip Icons while boosting fortifications! I have been boosting for over 4 hours not knowing this. If you change the options, all your levels you have gained in that session will be reset!
