As in the official games, X acquires new weapons by defeating one of the main 8 bosses. These weapons consume ammunition, which can be refilled via save capsules or from blue item pickups in the field, in addition to potentially having interactions with skills or items. Unlike in the official games, these "special weapons" do not require an arm upgrade to charge; instead, their charged variants are unlocked via spending points on the requisite section of their independent skill trees.

Skill Trees

Each weapons has their own independent skill tree adjacent to X's main skill trees. The upgrades are mainly about charge, cost, weapon's effects, and a special charged attack, but may vary depending on the weapon in question.
