At this point, no one should be surprised that a big-budget release like Dead Space 3 is going to get some downloadable content. Usually early bits of DLC include cosmetic items or extra weapons, so we expect DS3 to feature some microtransactions. But Visceral is apparently setting its sights on story content too, which will follow the game's release by only a few weeks.
"The team is hard at work on a top secret additional story that will be coming in a few weeks," executive producer Steve Papoutsis said in a dev blog. "We're not saying much, yet - but think 'disturbing' to get your imaginations going."
"Disturbing" goes hand-in-hand (or needle-in-eye) with Dead Space, and the game has always lent itself more towards moody, atmospheric stories. For those who want to look fashionable, the blog mentions that the game will also feature some more suits to buy on day one, similar to Dead Space 2.
Finally, Papoutsis announced four game modes that unlock once you've completed the game. New Game+ is back, obviously, but there are three others. Classic imitates the first game, making it a single-player only experience and eliminating the crafting. Pure Survival Mode makes the enemies only drop resources, forcing you to carefully consider what to craft. And Hardcore Mode limits you to one life for the entire game.
