Dead Space Hints for iPhone/iPad
Try to avoid hitting the belly of a Pregnant to prevent it from bursting and unleashing Swarms that will latch onto Vandal's body. Also be on the lookout for power nodes hidden in cabinets that blend in with the space station walls.
After a battle always remember reload as you don't want to be caught with an empty firearm in a surprise attack.
Double-tap on Vandal to turnaround 180-degree. This is useful for quickly turning around to check your back for Necromorphs trying to flank you.
Although you can riddle them with bullets to get a clean kill on a Necromorph you must dismember it by severing it's limbs.
A good way of increasing your power and defense ratinigs is to purchase a new suit. You can boost your HP by fusing your RIG with power nodes at a bench.
This feature is tied to the level of difficulty. For example, if you beat the game on Normal difficulty setting and select New Game+, you will continue on Normal difficulty.
