State of Decay

Check out the comments to my solution to find an even better way to beat the sieges, hehe. I recommend you read through mine as well because I have some good tips.

If you find it hard to survive the sieges, here's a very helpful tip:

The female character you start out with has "Shooting" at maximum from the start. Make her special ability "Assault rifles" and "Focus aim". When the threat level closes in to 3, make sure you are close to your Supply box in the base and stack up on:

-A big backpack to maximize slots
-A good assault rifle and 120 ammo rounds(four slots in your inventory)
-Some medicine that will heal your health(3 will only fill one slot in your inventory)
-MRE:s, 3-6 of those because when you use focus aim, your cardio-meter depletes and you need the MRE:s to get it back up
-A good blunt weapon, if you have to go close combat.

First of all, always restock the traps(it costs 2 + 2 ammo units). I never "bought" the fireworks or the small propane tanks.
Then when zombies start to swarm the gate, aim with left trigger and press left bumper to activate focus aim which causes everything to slow down, giving you time to do at least 5-6 one-shot-one-kills in the heads of zombies. You CAN shoot through the fence/gate! When the focus aim ends, quickly eat a MRE and you are good to go again.

Do now waste ammo on SWAT-zombies. They have helmets and those guys you unfortunately more or less have to let in through the gate and melee. Kill as many normal zombies as you can around the SWAT ones, then let the SWAT ones in and kill them melee-style and after you have the area clear for a couple of seconds, approach the gate and hold Y to repair it. Good to go again!

I was lucky to have a soldier with a shotgun guarding one gate and he vaporized SWAT- zombies with his shottie. In other words, it is good to recruit a lot of soldiers for your siege-defense.

The Juggernauts(superbig zombies) might seem scary, but just use focus aim and go for the head which will explode in glorious brain goo after 4-5 hits. Same with Ferals, go for the head.

Sieges get harder as you go but also get easier if you prepare. Make sure you build up your influence when your not on missions. Grab weapons and bring them back to your base or outposts and store them to earn influence. Try and find grenade launchers to bring back and give them to your teammates that you don't use much, they will have unlimited ammo and take care of a lot of the zombies. Keep your mines and explosives stocked around your base and stock up on ammo, food, health and explosives. Have some drone recons and grenades on you in case it gets out of hand. Later on you can use the snipers and the reinforcements to make it even easier. This is a video of my 10th siege and I barely had to do anything lol

Although I do not have this achievement (yet!), I'd like to add some advice.

This DLC has a different flow from the main game since there are timed base sieges that you will need to respond to. These occur about every 30 minutes and you will have to drop everything and hustle back to base when they occur.

When you first start the game, time does not pass, the number of zombies stays very low, and special zombies/hordes do not spawn* until you complete the first real mission. For this reason, it's a great time to do a few things:

- Drive a full loop of the highway and get off at every exit.
- Hit every observation post and scout.
- Create outposts at each drone site, satellite uplink, and artillery location (6 total).
- Drop your other two outposts at strategic scavenging locations.
- Loot every gun-oriented location. You especially want grenade launchers.
- Loot locations near your outposts but leave the rucksacks alone unless they are materials (see below). Don't forget that each outpost has a supply cabinet that is linked to the one at your base, so fill 'er up.
- Get a military truck, which is probably the most useful vehicle in the game.
- Load your truck with six materials. When you get control of your base you'll be in good shape to kit it out.
- You'll have a LOT of influence from stashing loot if you are doing a good job, so be sure to start filling up on drone strike markers for the achievement. They are also really handy during the later sieges.

You'll start to tire after a while, but the low threat level doesn't make this a big deal. JUST BE SURE TO COMPLETE YOUR MISSION BEFORE YOU EXIT. Otherwise, the game won't save!

Starting with a good initial setup will make your life a LOT easier.
