Yeah there is basically zero information on it when you start. I feel others who have played Warzone have a basic idea but I went in completely green and had to learn from scratch. Really enjoying it now though and up to level 39 after the weekends XP boosting.
Gear up, dive in in a group of 3 and stick with them. You can go on your own but its hard at first. You have 45 minutes to do what you need to to and get out via exfill helicopter which you can see on your map with the little exit door icons. When the 45 is up it sets a 15 minute count down where the cloud starts creeping across the map. The zombies within it are super high level so if the cloud doesn't get you, they will.
Do contracts in tier 1 in order to get 5,000 essence. Once you get that much go to a pack a punch machine and upgrade your gun, then you'll be better suited to go into tier 2 where 10k essence gets you an upgrade. The better gear is in here too, 2 and 3 plate armour vests plus bigger backpacks.
Some contracts are easier than others, the ones with mercs are the harder ones. Other players will also be looking for the easy ones so get there first.
The gear you find and carry can be brought out with you upon successful exfil which includes the armour vests, backpacks, self revive kits and mods. Any gun you bring back with you will be unlocked form then on in your armoury for use across all forms of MP. If you die or miss the last chopper you lose the lot. Play around with the perks and the weapon upgrades and put them in your load out for each run. They are one time use and last the duration of that particular run so pop em as soon as you rope down.
It's pretty hectic at first but once you extract a few gun upgrades it gives you a leg up on your next run and then tier 1 becomes a bit of a cruise, allows you more time to orientate yourself and familiarise yourself with the mechanics.
