The only thing Isaac Clarke engineers in this video are some mad lines, yo.
When he’s not constructing brutal weapons that he can use to strategically dismember the unsuspecting denizens of Tau Volantis, Isaac can usually be found practicing his rap skills. He’s got mad skills too, and there’s no denying he’s had a tough life after surviving multiple Necromorph encounters only to see his girl Ellie leave him for a total dick, plus there was that whole needle to the eye bit in Dead Space 2. I’m sure he uses all that strife as fuel for his rap career. I’m sure that’s real healthy.
