Returnal features dozens of weapons, and while Selene can only hold one at a time, things aren’t as lopsided as they might sound, as each weapon has a handy alt-fire feature.
Returnal assigns each of the 10 weapons an alt-fire feature pulled at random from a pool of 10 alt-fire features, and Returnal has 90 Weapon Traits.
Each weapon also benefits from Weapon Traits that further augment abilities and can both be stacked and leveled up.
Holding the “L2” button halfway down uses the weapon’s standard feature, while pressing it all the way down activates its alt-fire mode.
