Palworld isn't just any survival game, no, it has actual bosses that you need to complete in order, similar to how Valheim handles their boss fights. You'll progress through the world and fight bosses as milestones in the game. This way, you'll always have a new goal to get to and progress you forward in the game. This is part of what makes Palworld so addicting and fun.
To get started, you'll want to establish an order in which you'll fight the bosses in the game. This is generally the best order to fight the bosses in.
Zoe and Grizzbolt are an exciting and tough way to get started with the bosses in Palworld. You'll want to bring as many ground type Pals as possible because they are super effective against the electric type Pals you'll be fighting here. Your best bet in this fight is to get your Pals to take aggro and use a melee weapon to hit Grizzbolt.
If you couldn't tell by the picture, this is a grass type fight. So that means you're going to want to bring fire type Pals. Generally you want to avoid the water bubbles and call your Pals back when they're out so you can avid getting hit, hide behind a pillar if you see the large bubble. Continue to use your Pals and weapons to take her down.
Things by now are starting to get a little more difficult. Orserk is a dragon and electric type, so you'll want to bring your ground types and ice type Pals out for this fight. In this fight, it's best to let your Pals fight and do as much as possible while you rotate them, and then keep your distance and use ranged weapons to chip down Orserk as much as possible. Keep your distance.
This fight gets taken into the air, so make sure you're prepared with plenty of ammo for your ranged weapons and have Pals that can fly or shoot projectiles. This fight is similar to Orserk, let your Pals take aggro and used your ranged weapons to do damage to Faleris.
The final boss in Palworld is tough, so make sure you're ready for this one. Shadowbeak is a dark type so make sure to bring dragon type pals because they are super effective. Make sure you bring a ton of healing items as well as ranged ammo that does a lot of damage, because this boss fight is going to take you a long time otherwise.
Those are all of the main bosses in Palworld in their respective order. If you want to fight these bosses with your friends, consider grabbing a server from indifferent broccoli.
