This guide is meant to help people get the Untouchable achievement without the help of other players. That may sound like a hard task, but it's acctually really easy if you have the right strategy. Now, I'm going to show you my strategy. Step-by-step.

The information in this guide will be arranged as day to night (excluding night 1, which has no day phase.) For example, On night 3's section I will first show you what skill to invest in, what to buy during the day, and then tips on surviving the real combat of the night.

Since how much money you earn each night doesn't seem to be the same every time, this guide is going to assume you have picked up almost all of the cash the zombies drop each night and have enough to make the purchases shown for each night in this guide. If you can't afford to carry out the day phase tasks detailed in this guide, hold off untill you have enough money. Lack of money shouldn't be an issue.

Night 1 is really simple and self explanatory. The zombies are slow and are no match against a pistol. With little effort, you can outrun the zombies and kill them. Be sure to pick up any supplies they drop. Remember, never to risk getting hit for supplies. It can set you back to square one. Use caution.

During night 2's day phase, purchase a shotgun, and as much ammo as you need. Not too much ammo. I like to keep a minimum of 20 ammo. Simply repeat night 1's strategy and make sure the zombies get blasted before they get too close. Alternately, you can swap night 3's strategy with this. Purchasing Palisades on night 2, and the shotgun on night 3,


.

Now that night 2 is over, you're going to be given a skill point to distribute. Put it into Pickup Range. This will help you get the items on the other side of Palisades without having to put yourself in considerable danger.




For the day phase, purchase 12 Wooden Palisades and place them in this pattern. Note how the corners don't have Palisades on them. This is not an oversight. These corners will allow you to enter and exit your Palisades when you want.

I would like to say again that, you shouldn't leave your Palisades to go for supplies unless you are certain you can do so without getting hit. It is hard to tell if you got hit sometimes. I like to use the full ammo bar below the health bar as a reference point. It sucks to lose, but it sucks more to find it out when it's night 10.

Next, buy as much extra ammo for the shotgun as you need to feel comfortable (I like to have at least 40 on me at all times. Don't buy too much ammo!.) It's time to start the night's combat.




Don't focus too much on any particular spot. Try to stop the zombies from attacking a side for too long. Your shotgun will come in handy for this purpose. They should have a tough time breaking down a Wooden Palisades on night 3, but better safe than sorry. Remember, no matter how much damage they do, it only take one (1) hit to ruin this Achievement. If at any point they break one of your Wooden Palisades, replace it during the day phase.

Buy an Auto Turret, and place it in one of the four interior corners of the Palisades. Buy an smg and mount it on the Auto Turret. If at any point you can't afford an smg, use a pistol. It should be a good temporary substitute until you can afford an smg. Buy as much smg ammo as you can afford (try to keep it below 30. Don't spend too much money.) and begin night 4.

With the aid of an auto turret, your job will get easier. Make sure they don't run out of ammo. As a rule of thumb, I like to keep 20 smg ammo on me per turret. For example, keep 60 ammo for three (3) Auto Turrets. From here on out, the night strategy will be to gun down the zombies as they come. Your turrets will make short work of them as you buy more each day.

The day has come. With it, another skill point. Put it into Pickup Range again. You're not quite upgraded enough to be able to pick up supplies on the other side of the Palisades, but you'll be there soon.




Same routine as the previous day phase. Buy an Auto Turret and put an smg on it. At this point you may have stopped worrying about shotgun ammo. Hopefully because, you have so much, rather than you simply forgetting about it. Ammo pickups are very helpful and can save you money needed for the next night's preparations. The next two day phases, you'll get two more Auto Turrets. Buying one each day is just for added protection. If you can't afford it, don't worry. You'll be able to afford them eventually. Now, begin night 5.

Now, you'll be putting up your third Auto turret. Make sure you have plenty of ammo and begin night 6.

You have another skill point. Put it into Pickup Range, again. Now, with 150% Pickup Range, you can pick up supplies just on the other side of a Palisade.




Now, it's time to buy your fourth Auto Turret. Now that you have four turrets, you won't be buying anything new on night 8. Don't forget to buy smg ammo on nights 7 & 8 though. We're saving for Electro Palisades on night 9. I prefer to wait until I have all four turrets and then upgrade the Wooden Palisades to Electro Palisades. The turrets help make sure the Palisade doesn't break in the first place, so you can focus on turrets before upgrading Palisades. I like to upgrade all the Palisades at once. That costs $18,000 if they're not on sale.

Now, you can increase Pickup Range to the max of +200%!




As I said, Electro Palisades are expensive. I started small for night 9. Blocking the corners with Electro Palisades because, at this point, you won't need or want to leave the safety of the Palisades. Replace Wooden Palisades with Electro Palisades If you have the money to do so. You're so close! Get ready to fight! Make sure you have plenty of turret ammo.

Now, you should have all, if not most, of your Wooden Palisades replaced with Electro Palicades.
This is it. The final night. Survive this and the achievement is yours. Good luck. Remember to check your ammo count.

If you didn't get hit once during that run, you have the Untouchable Achievement. Congratulations!
