Rely on Horror runs down the information revealed on Dead Space 2 in the new issue of Game Informer (thanks GameSpy). The article boils down to a scarier sequel, intuitive missions, more puzzles, gravity changes, locales such as shopping malls, schools and churches, Isaac will be seeing the infection from the very beginning, awesome weapons and more grotesque but interesting monsters.
This time players will be introduced to Issac. He will have a speaking role in the game, and more depth of character.
He won't just be a man with no opinions doing everything he is told to do, he does have a mind and will, even if a big part of that is now a bit twisted in the head. He is seasoned in fighting the necromorphs and he is a veteran at fighting them, even put in charge of necromorphs by the people just because he survived the attack, people around him looking for a savior will turn to Isaac just because he lived. Isaac is out to make a difference, but can he stand the pressure put on him along with his continuously twisted mind? Apparently we're going to have to make the call, Isaac's judgment is not in the right light, his mind is still twisted from the first experience he had, and it's only getting worse.
