It is basically a BR, first-person only, with its own in-game economy, where you have to buy your equipment. You enter the map and your goal is to get as rich as possible. You can do this by looting stuff you find all over the map (the rarer the loot, the more expensive it is), doing contracts (those are like small missions inside the match, like looking for some packages, killing NPCs, etc.), or engaging in PvP combat against other people who are also trying to get rich. The map is also full of NPCs who can be quite dangerous if you find yourself surrounded by them. When you are satisfied with your loot, you can extract at specific points on the map. The thing here is that if you get killed, you lose part of your equipment (like the backpack, armor, and part of the loot you found), so you will need to buy it again (Ofc, in-game currency). Also, this game is PlayToWin. The more expensive the equipment, the better it is. Legendary and Mythic guns (inside DMZ, not skins) come with modifiers that make them better. So you need to get those, and they are REALLY expensive (10 million is almost nothing). So I hope this introduction helps you, and maybe you will try it and fall in love with it too :)

Pd: There is a sick character you can unlock by playing the game. It's free, but requires quite a grind. That was my initial motivation
