It’s a shame it takes so long to unlock, but getting four weapon slots is a bigger deal than most think. Being able to carry different weapon types for each engagement can help expand the strategy when it comes to the enemy classes and whether they have shields, armor, or just health. Once players unlock all four weapon slots in Borderlands 3 the game opens up even further than before. With 23 chapters in Borderlands 3, that puts things a little under the halfway mark. In our playthrough, the fourth weapon slot in Borderlands 3 didn’t unlock until our character was about level 24. However, there are missions that will take the player away from the planet, so don’t be confused.
Without going into spoilers, it will be obvious enough to players when they are “done” with Promethea. Basically, players will need to complete all of the main missions on the planet Promethea and the fourth slot will unlock automatically. RELATED: Borderlands 2: Ranking All Legendary Pistols.
True to its origin, the HellFire has a similarly incendiary power. Getting the fourth weapon slot in Borderlands 3 is going to take a lot more progress than unlocking the third. The HellFire is a submachine gun that has a greater chance to be obtained from Scorch, the fiery spiderant located in Frostburn Canyon during the Cult Following quest line.
