Why does the shop sell a variety of engineering suits, and tools to Isaac? Because on his RIG, he's still classified as an Engineer for the CEC.He's her 'brother' in the sense that he belongs to the same order as her. Franco's black and Daina's white the possibility of adoption aside, this is most likely yet another slip on her part. Daina also yells that her 'brother' died to get Isaac out of that hospital.Now consider that he is a fully devoted Unitologist alongside Diana and that gruesome part of his transformaton becomes forshadowing.

Slashers made from believing Unitologist. Well the peeled face effect does appear on other Necromorphs. However most slashers you'll encounter still have existing faces, so why does only he shows this kind of transformation. Franco's death/transformation into a Slasher is very gruesome but contains one strange element.So not only was he tortured and kept suspended like that for years, ultimately he was to become the catalyst for making whatever the heck the markers are trying to create. Then add in what Nicole hallucination says near the end, that convergence requires one last body, that of the maker of the marker to be added to it.They've been steadily erasing memories repeatedly to ensure that he's in the right frame of mind for their experiments, prolonging his suffering and preventing closure. And the asylum has deliberately kept him there. He hasn't had any opportunity to come to terms with Nicole's death he's still shell-shocked, emotionally drained, still in desperate survival mode, and still clearly suffering.

Keep this in mind: To Isaac, it's only been a few days since the events of the first game.

'Isaac, we're all gonna burn for what we did to you.' One might first think that was just referring to the physical torments the asylum's doctors put Isaac through, like the horrible eye-shot that stimulated the memories of the Marker's influence.

Newbies to the game may not understand the Strategic Dismemberment game mechanic, therefore they pound the Necromorphs and waste the ammo given, while those who had played Dead Space 1 save the ammo and money!

In Chapter 1, when you get your first plasma cutter (and kill a poor guy in the process), you find large amounts of plasma cutter ammo lying around.
