On the island, there are several locations with different buildings (towns, camps, power stations, military bases, etc.). There are places with a lot of loot and it is of high quality. But here you will have to fight for it immediately after landing. And there are small locations where the loot is barely enough for 1-2 players, but at the very beginning it's calm here.
Periodically, a bombardment zone appears on the map, into which it is better not to meddle unnecessarily. Also, look out for airdrops (boxes on parachutes) which will contain high-quality weapons, disguise items or other useful perks. There are also several types of transport in the game. You will need it in order to quickly move from one location to another, and to always be in the safe zone.
There are plenty of weapons in the game: pistols, semi-automatic guns, machine guns, assault and sniper rifles. There are also four types of grenades. The most interesting thing is that in addition to first-aid kits, there are also boosts. These are energy drinks, pain relievers, and adrenaline syringes. All this will help you passively restore health and run fast. Good luck!
