1. When there are too much aggro in the area you are looting, run for your life!!! Unless you want to get killed.
2. Its best to read the mission definition in DEAD FRONTIER WIKI-MISSION before doing any mission so you can get full details, or watch the walkthrough on youtube.
3. When you see a boss zombie it's best to level up to at least lv50 to battle it on your own or its going to be a very high risk of you dying. Another thing is that you should run for your life if your under lv50 and not capable for battling the boss.
4. When your looting always watch out for siren zombie. There are two headed females and females only!!!
5. Always save up money in case of any emergency like medical services, food services etc... Save up at least $1000 if you're at Nastya's Holdout. Save up at least $2000 if you're at Dogg's Stockade. Save up at least $5000 if you're at Precinct 13. Save up at least $6000 if you're at Fort Pastor.
6. When you're battling a zombie it's best to use the circling technique to eliminate it. Simply use melee weapons, hold down your the attack button and circle around and hit the zombie at the same time.
7. Always save up ammo in case of emergency.
8. If you have too much, either you leave them in your storage or sell them in a reasonable price.
9. Pick up any loot that are useful for you, if not then don't.
10. ALWAYS PICK UP CASH no matter how much it is. Unless you want to be poor.
11. If your on a simple loot run always loot around the base you are in.
Thats all my recommendation for you. If there are any problems PLZ leave a comment or text me. If there are any more recommendation I'll update this post.
