It's pretty fristrating at times visibily working on trophies for this game. However, the platinum isn't actually that hard.
The best thing to remember is that each of the story missions are set within the Yellow markers on the map. Orange are Jobs and are optional, but you need to do these as they unlock to gain the platinum. These jobs include the "bounties" and "Marauders" side stories.
Use Cascade to get the majority of the trophies.
Start by doing the collectibles, Historical Markers are the easiest to find and if you see any Stones standing in a pile, kick them down, as these will cut the time down for the trophy,
This is also a prime time to start:
Which is for activating the NERO Checkpoints. Your first one of these will also unlock,
Then find and take out all the Ambush camps for useful upgrades and a new safehouse, and also starts you off towards:
Next tackle the Infestations, at the start of the game, these are a tint bit of a nightmare and the Graveyard also has a Horde standing guard over it. So, It's best to go during the day and use hit and run tactics rather than fighting the Freakers that escape the flames.
This starts the trophy
Taking out all three of these groups in Cascade also unlocks:
By proxy, you'll have to remove a horde before doing one of the NERO checkpoints unlocking:
Do you like my collectionMake sure you hunt down all the character collectibles, NERO recorders and Historical markers, as well as the Herbology plants which will unlock:
Keep doing this in each new area of the map, you now don't need to worry about Hordes, unless you want to boost your XP.
By the midway point of Lost Lake (the 3rd area) you should hit:
Then if you apply this to the Southern regions:
Leveling upBest way to do this is to kill Hordes intermitently and do all side missions on top of the mainstory.
Killing SpreeThe Kill trophies are actually a little easier than you'd expect in a zombie game.
Use Ambush camps and Marauder camps to boost.
You can also use unsuspecting Zombies in a boost for this. Only Melee stealth kills count.
The easiest one is:
Just keep raiding the Ambush Camps, Some of the more powerful ones in this storyline are one hit kills on low level Freakers and Humans.
Just remember that both Poison and residue bolts take time to kill the person, so don't get bored and kill them outright.
Gain the Melee upgrade in tier V to unlock double boot knife damage. Then the easiest to fight hand to hand after a bit of weakening with guns is the Breaker. His attacks are predictable unlike the other two and they are normally alot easier to outwit.
We are familyDon't be disheartened if you haven't got a camp to Allied status before you go South.
The Lake Diamond camp is the easiest in the game to unlock this on
When you go North again, it's really easy to get them all to allied.

We are AliveThe
trophy
Requires 10 survivors to be saved.
There's two ways you can earn progress to this.
Doing the side stories for "Protecting the weak" and finding random encounters for saving someone from an camp or Freaker attack and sending them to an camp.
If you find an group in captivity then all four will count towards this.
MotorstormThis can only be unlocked after gained Allied status with Diamond Lake and unlocking the Nitrous Upgrade 3 for your bike. Then using it during a drift for 5seconds.
There are two great guides for this but you can do this in natural gameplay, as I did.
