That announcement is a new teaser trailer for the game's first DLC, Vault Hunter, coming in the expansion, and it is none other than C4SH. Here is what we know so far about this mysterious gun slinging robotic Vault Hunter. This eventually led C4SH to quit his job at the casino and become a Vault Hunter, seeking his own fortune and place in life. Randy Pitchford states that as a Vault Hunter, C4SH uses the powers of chance and probability via rolling dice or playing cards to inflict random effects in battle. However, this new Vault Hunter, C4SH, may be up my alley despite only seeing a few seconds of him through a teaser trailer.
