I've got some friends who are just getting into this and I wanted to make a beginner's guide. Feel free to add to this, as I'll just be linking the direct post in our facebook group, and I can edit in any other good advice.
-Keep in mind this is for beginners only! Eventually you will outgrow some of these tips and behaviors. This is just to help you get eased into the game.
Rules
Pretty simple. Both game modes are just about killing the other team. The only difference is that Supply Raid has you respawning after you die, where Survivors is just 4 vs 4, first team to win 4 rounds wins the match.
In Supply Raid, if you gather supplies and weapons, you'll keep them when you die. In Survivors, all items and special weapons are reset each round except the ones you buy with parts.
Basics
You earn parts for everything you do in the game. Think of parts as currency, because you buy ammo, armor, upgrades, and weapons with it during matches. There are more ways to earn parts aside from killing enemies. You can get them by making items, marking enemies (click right stick when an enemy is in your sights and your team will see them) downing enemies, healing teammates, reviving teammates, and giving gifts.
If you find that its hard to get kills at first, focus on supporting your team and crafting as many things as you can. Once you have all the perks unlocked, you can be the top scoring player in a match just by helping out the most. Teamwork is really rewarded, and I'm not just talking about flanking!
Supply Boxes are scattered around the maps and show up as a white dot on your radar. Open them up to get all the ingredients for bombs, molotovs, shivs, etc. Make these a priority in every game.
Loadouts
You won't have all your loadout points unlocked yet. You'll need to experiment with all the guns and see which ones suit your playstyle, however I recommend the semi-auto as you can down an enemy in as few as 3 hits with it. When its upgraded, its pretty accurate from long range and you can pop off several shots before reloading or running out of your starting ammo. Others may recommend the bow, but I've personally found that weapon to be a bit more difficult to use, though its stealth perks are undeniable.
As for your perks, start with First Aid 1. Why? Because you'll heal yourself much faster than you would without it. This can really be important when you get winged and you see enemies closing in on your radar.
Also try Crafter 1 and 2. Remember, ABC: Always Be Crafting! This will eventually become your most important perk when you want to keep the clan in your meta-game alive or you just want to have a lot of parts to spend each game. At first you'll just create things quicker, but once you get Level 2 unlocked, you can give a gift to your teammates for every 3 items you make. This gets you parts that you'll want to remember to spend on weapon upgrades. Make whatever you can, when you can. Don't hoard ingredients in the hopes that you'll eventually make that elusive molotov, just make what you can and go with it! You might die and lose all your ingredients if you're playing Survivors, so make that shiv and health kit beacuse that's an easy 60 parts for you right there.
Also try Covert Training. The 2nd level of this lets you hide from enemies' radar when moving while crouched. This really helps you slip in behind enemy lines when needed, or make a sneaky escape if you feel like you're in a bad spot and want to relocate.
What should I do?
Again, remember ABC: Always Be Crafting! A typical game should consist of you and the smart members of your team making their way to every available supply box on the map. Should you meet resistance at a supply box from the other team, you may want to consider hanging back and seeing what they do before you go trying to push your way in. These boxes are important because they don't just supply you with extra weapons, but sometimes they have 100 parts in them and the items you make are also netting you parts. Again, all this should be spent in the store (R1 while in your backpack) on weapon upgrades first, armor second, ammo only in a jam or when you know you're going to get into a firefight.
Make weapon upgrades a priority because once you buy one, you'll have it for the rest of the match. Armor will stick with you between lives/rounds, but it can be destroyed and you'll need to buy it again. That's why I always make it a 2nd priority over upgrading my main weapon.
LISTEN! Listen Mode is limited, unlike the campaign mode. However, its super useful and you can see enemies through walls as long as they aren't sitting still or using the Covert Training perk, which hides them as they move while crouched. Once you get a little ways from your spawn, or in the case of Supply Raid, every time you spawn, its best to listen to Lt. Dan: Shut up! Get down! Listen!
Stick with your team! Sometimes you will have idiot teammates that are just suicidal. You'll have to know better than to follow them into the frying pan. Eventually you'll want to play around with flanking on your own if you feel like you can pull it off, but the majority of the time you are best off when you have at least 1 teammate nearby who can watch your back. You never know when an enemy is going to crouch out of the dark with a shiv ready for your neck, so its good to have an extra set of eyes and firepower!
Outnumbered? Get to any surviving teammates you have, but try to keep down and quiet if possible. Sometimes you'll have to run and get organized once you're there.
Alone? Get to a supply box! Normally you'd need to make bombs/molotovs/etc. but in the event that you are the last man standing on your team, a supply box will have these ready to go! Expect 1 or 2 of each, which could be the difference between putting up a good fight and going down in flames. If you can pull it off, grab this stuff, find a spot to hunker down, and lay bombs all over the place! Then get your molotov ready to throw at the first sign of ANYTHING.
Be okay with dying! Its going to happen and it doesnt matter. Just have fun! Try supporting your team with gifts and heals, sneaking up on enemies for stealth shiv kills, or whatever you want. Play around with the different weapon loadouts and see what feels good!
Good stuff to know
Smoke bombs are good for more than just creating a cloud to hide behind. If you can smoke an enemy, they'll be stunned for a moment, allowing you to run up and shiv them from any angle, as opposed to the normal rule that they can only be shiv'd from behind. Or if you don't have a shiv, just shoot them while they're stunned!
Molotovs have crazy range! If you even SEE an enemy holding one and looking your way, get outta there! If its in the air and their aim was true, well, YouAreAlreadyDead.jpg.
Bombs work differently than in campaign. If you just press R1 with it equipped, you'll set it down and it now works like a proximity mine. If you aim with L1 and throw, it will detonate shortly after it lands. You can also spot the ones enemies have laid with Listen Mode and you can mark them for your teammates to see once you have them in your crosshairs, should you not want to blow it up for some reason.
There's no friendly fire. You can bomb yourself out of existence and accidently set yourself on fire, but your teammates will not pay the price for your bumbling.
If you die, you may want to set up for the next round by making your purchases in the store before the round starts. This kind of thing would allow you to do something wild like buy a Military Sniper Rifle and as soon as the round starts, sprint up to the equivalent of the 50 yard line and pick off your enemies by surprise!
Some people will say never craft a health kit. This is true only some of the time. Yes, they are already scattered around the maps, but you still get 30 parts for each one you make and sometimes its best to just make the damn kit and get your parts.
Last thing and I'll say this again because it bears repeating, HAVE FUN! Don't worry about dying, take it all in stride, and remember its just a game. When your corpse gets teabagged, and it will, learn to laugh about it because at some point you'll have your moment and you may be returning the favor. Hell, your whole team may be in on it if you pull off a sweep!
So enjoy. This is one of the coolest competitive multiplayer shooters to come along in a generation that has been craving innovation like this for years.
