Borderlands 3 is a game which focuses on exploring unknown planets (not just Pandora) and fighting enemy troops. The following chapter will explain how battle in Borderlands 3 looks like.
The entire gameplay focuses on exploring new locations. During your adventures, you may encounter both friendly and hostile characters. As much as the first group can assist you to some degree during the gameplay (e.g. by providing additional equipment), hostile characters will attack you without hesitation.
The fight itself is very dynamic. During battles, you will often have to use all sorts of covers and evasions. Of course, your character is also equipped with a shield. However, shields have their limits and will deplete with every hit. Shields durability and regeneration time are also affected by various character's skills.
An important element of the game is searching for new equipment. All locations are filled with different kinds of weapons that can be found. You should be aware that even a restroom can serve as a hiding place.
