Sooner or later you're going to want to carry more weapons in Mass Effect: Andromeda. When you do, there's a solution.
Head into the skill trees menu and look under Combat. There's a branch in this section called Combat Fitness, which when upgraded to Rank 3 will allow you to carry a third weapon. Your loadout space can be upgraded further with Rank 5.
Due to the implications of having access to more weapons that can counter additional types of enemies, Combat Fitness is regarded as a high value skill. Although not necessary, it can be hugely beneficial.
