So this streamer called awildwatermelonappears called in 3 airdrops, for which he paid. These airdrops contain a range of items, including weapons, ammo and backpacks. Here is a picture of his third airdrop.

As you can see in the bottom left of the UI you can indeed buy Airdrop tickets. In the top left of the UI you can see what was in one of the crates he called in via payment. This was included in the airdrop for which he paid:

• Tan Military Backpack
• Waist Pack
• AR15 (rifle)
• Land Mine
• 2x First Aid Kit
• 90x .223 Round

It should be noted that even if you buy and call in an airdrop you are not guaranteed what is in it as you could be killed before you can take what's in it meaning someone else can take what is in it.
This is what a H1Z1 developer said 3 days ago in a stream: ''You can't buy ammo, you can't buy guns, you can't get them out of a crate (this is another type of crate, not airdrops), there's 0 way, you'll have to find them in the world.''

Barf.

Wait, he's paying money in an early access game? That's crazy.

If it does end up being the case, that's not good at all. Still, I would need to know more about the game and I'm not going to base too much off early access. Often, developers will change things in early access games so they can evaluate components faster.

Doesn't that add to the realism? I mean that's how rich people will deal with a Zombie apocalypse.

That's what people do in PC gaming, it seems to have become almost normal practice there.

fail. not even considering this game anymore.

Since it's free to play, it only seems fair to also be pay to win.

Now, if it were pay to lose, that would suck.

Anyway, never really cared for this game, now I definitely don't care at all.

was not really interested from the beggining and now i dont even care anymore...

doesn't bother me,still interested in the game

Doesn't actually seem that bad, to be honest.  Reminds me of those random treasure boxes you can buy in some other MMOs.  Response from John Smedley:

I'm going to weigh in here on this subject. We've been showing it clearly in all of the streams we have been doing. I made a point of personally doing it during last Friday's streams. We want them to be server events... so we make sure the whole server knows they're coming and I've personally been killed many times after I paid for them myself. So I fundamentally disagree with the argument. In terms of us not being honest about it - untrue to an extreme. Quoting an 8 month old reddit post after numerous streams and interviews where we've been quite public AND putting it front and center in our "What to expect document" which was right on the purchase page just makes this blatantly unfair IMO. (here's the link - https://www.h1z1.com/dev-updates/h1z1-what-you-can-expect-in-early-access) or you can just go back to the steam page. So if you think it's P2W don't buy it. Don't play it. But I have to say wait until you've personally tried them before making the call. We included airdrops in both the $20 and the $40 versions just so you could see for yourselves. But to clear up the misconceptions - 1) You cannot call in airdrops until the servers are 1/4 full. 2) You can't call in airdrops without generating a ton of zombie heat. 3) the airdrops are random in what they deliver. 4) you are not guaranteed to get a single thing out of the airdrop you called in. You could die trying and you're out the money. 5) We fly the plane in very slowly and loudly.. we also stream green smoke from it you can see from very far away. This is all I'm going to say on the subject. We've been straight about it. We've called attention to it publicly and it's something we've decided we want in the game. It makes it more fun. It can shake things up. Please don't judge based on knee jerk reactions. Try it. Or watch more streams with people doing it.

Now with all that being said - we're going to be making some big changes to them in the next day or so.

1) Dramatically widening the radius they come in - it's too small from what we're observing. 2) Making sure the chance for guns is a much lower chance so they are much more rare. 3) Upping the minimum number of people on a server to even allow air drops. It's set at 50 right now and we're going to at least double it. We are serious about these being server events and contested. 4) Making the plane fly even slower.
