It's $30, not 40. The devs said there are no plans for sales, especially since they've already sold over 2 million copies. It's already the #1 most popular game selling game on Steam and #2-#3 in concurrent players.
No text chat. We use our own voice chat on Discord, but PUB does have voice built-in.
There's a lot of panic in the game. The guy who made it has been perfecting the idea for awhile and this is his 3rd game doing it.
100 people. Start in a plane. Plane has a random line direction over the map. You jump out and parachute (as 100 other people do!), but first pick the best possible location. Do you want to get great loot? Then you'll have to fight tons of other people early on. Alternatively, you can try and get far away from the plane and loot the scraps so you can get a reasonable weapon loadout.
Every few minutes a circle of blue wall closes in. If you're outside wall, you get hurt. The more times the circle shrunk, the harder it hurts. You can med up and survive the first one or two. But if you don't get ahead of it, you'll soon play a losing match of "run away from the wall."
Vehicles are great for moving fast. But they're LOUD AS HELL in a game where half the battle is knowing when NOT to shoot. You DON'T want everyone to know where you are. Some vehicles carry only 2 people, some 4. Some are slower. Some have 4-wheel drive and provide varying levels of bullet protection.
You can take a vehicle and go only to the next circle end. Or, you can head to the center.
Once the blue wall finishes shrinking to the next iteration to the next "white circle" on the map, a ticker starts again (2 mins, then 1 mins, then 45 seconds, etc) a new "white circle" (where the new safe zone is) pops up, and the blue wall will begin shrinking again.
So there's all kinds of strategy "Do I vehicle it? If I can even find a vehicle..." verses proning slowly across fields, or crouch running along the hill line and then cutting down through some cover.
Each match lasts less than 20 minutes max, and if you die you can immediately start a new one (which takes 2-3 minutes to load). And the game... it's stressful and intense almost the entire way. You don't have any time to take your headphones off (<--really recommended! Sound is very important for spotting bullet directions and hearing footsteps.) to take a phone call or let the dogs out.
The likelyhood of winning is almost zero. I've won less than 5 matches in >50 hours. But it's not about "winning." A win, being the last person alive (or last duo or squad of 4 alive), is like winning the lottery. Just getting to the last 10 people alive is a huge achievement. So it's not so much about "winning" but about getting better and further than before.
I strongly recommend playing with friends though. Without that, the game would feel like such a painful slog that most people will become discouraged and frustrated. Playing solo is fun at times, but playing with friends is where it's at in this game. Otherwise, you play 10 minutes, let your guard down for a split second, turn a corner and find someone shotgun you to the face and your round is over.
Weapons are balanced well too. It's always a cost-benefit risk to "scavenging enough stuff" before the blue wall comes, AND, "what if I encounter enemies in that block of buildings and die?" But even the crappiest weapons are still enough to kill most end-game people if you're careful enough.
Go and check the (few) NEGATIVE reviews on Steam. They all still say "Great game. Except X."
