im still drunk but there 2 ways to cheese him.
1. stack fusion coils before you activate the terminal. blow them shyts up when he's near em.
2. at the start of the fight, there's a lil barrier you can keep hopping back n forth too little his health n shields, soon as he gets to the other side, walk or hop around n he'll take his time to walk around that barrier. this barrier is directly behind the control panel when the fight starts. its deff a longer way to do it but you will kill him chipping away at him this way.
