If you've been following Dead Space 3, you might have heard about a resource-mining glitch. By reentering and exiting a particular room, you can grab all the resources you want, thus circumventing any possible need for microtransactions. And you may have felt uneasy about exploiting the game, but don't worry. You have EA's blessing to farm till your heart's content.
"The resource-earning mechanic in Dead Space 3 is not a glitch," EA's Jino Talens told GameFront. "We have no plans to issue a patch to change this aspect of the game. We encourage players to explore the game and discover the areas where resources respawn for free. We’ve deliberately designed Dead Space 3 to allow players to harvest resources by playing through the game. For those that wish to accumulate upgrades instantly, we have enabled an optional system for them to buy the resources at a minimal cost ($1-$3)."
So there you have it. The purported glitch is not only not a glitch, it's an intentional design decision for players clever enough to find it and patient enough to use it. With that off your conscience, feel free to check out how to pull off the glitch, err, "feature" below.
