Like the first game, Borderlands 2 will include literally billions of weapon combinations that players of the four player classes—well, five if you include the Mechromancer—can arm themselves with.
In addition to the near-countless weapon combinations, Class Modification Units, or COMs, are also making their return in the sequel. Each of these COMs improve your character's abilities and much like the previous game, they will heavily impact your character's playstyle whenever you have them equipped.
Each COM mod serves a specific purpose and is designed to boost specific skills. These COM mods can even improve your skills well beyond their maximum level.
