- This page is about the Assassin character class. For the in-universe character, see Zer0.
The Assassin is one of five playable classes in Borderlands 2; Zer0 plays the Assassin controlled by the player. Assassins are effectively based off of Hollywood representations of the ninja: not built for a lot of direct combat, but designed to carefully and efficiently eliminate specific targets on the battlefield, one by one.
The Assassin's action skill is called Decepti0n; with it, he deploys a holographic decoy of himself and activates a cloaking device in the same instant. While the decoy draws the enemy's attention, the Assassin is free to move around the battlefield unnoticed. Also while cloaked, his heads-up display shows enemies highlighted in blue. Unlike the Phasewalk ability from Borderlands 1, the Assassin is still vulnerable; stray shots and splash damage can still hurt him, even if enemies can't see him.
The Assassin's melee attack uses an energy-based sword that he wears on his hip; the hilt of the sword exists at all times, but the blade is 'digistructed' by his Storage Deck each time he draws it. While the weapon cannot be equipped, per se (it behaves like every other class's basic melee attack) it can be upgraded by investing in certain skills.
