Dead Space‘s in-game interface has gotten a lot of attention. No doubt, the holographic displays look slick, and the way they’re presented in the game world does a lot to make them feel like a part of it, less artificial.¹ But it’s the fact that the interface does not interrupt the game that makes it worth mention. The fear and vulnerability central to Dead Space isn’t ever trumped by the needs of the UI—and critics noticed. Rarely has the unobtrusiveness of an interface been so acclaimed.

Not pausing the game while the player fiddles with her inventory is not new (it’s a design choice used similarly before—System Shock 2—and since—Demon’s Souls), but Dead Space pulls it off particularly well. Thoughtful design compensates, in part, for the lack of pauses and the limited time the player has to keep track of her stuff. By sorting, organizing, and keeping the inventory simple, the interface reduces the amount of attention the player needs to spend on it, leaving her to explore, shoot off limbs, and be scared.

See-through and sorted to be useful

In Dead Space, the player is often assaulted or surprised by monsters. The in-game interface takes up three quarters of the screen, but is semi-transparent so the player can still see advancing zombies while she heals, reads, or orients herself.

Once the zombies hit, the player will need to heal herself or refill her air tanks, but may not have the time or ability to run away from a fight to a safe place. There are buttons that allow certain items to be used without going through the inventory (using small medkits or reloading weapons), but sometimes the player needs to use an item in her inventory quickly, in the action.

To help her out, items in the inventory are sorted by their usefulness in frantic play situations: medkits are first, then air canisters, then stasis packs (fuel for the slow-mo ability), then ammunition. Within each type, items are sorted by size: larger medkits come first. When the player is running low on HP or oxygen, the items to alleviate her distress are the ones the fewest button presses away. She can restore as much HP as possible with as few presses as possible.

Small, separated, and simple

Even when not under pressure, the player’s tasks are not needlessly complicated. The interface remains simple and interruptible, not ruining or allowing escape from any surprises.

Items occupy a single inventory slot, no matter their size in the world. There is never a need to rearrange things in order to fit in another item—no inventory Tetris. The player either has space or she doesn’t.

Fortunately for her, things such as weapons, power nodes, or quest-specific items are stored and presented separately from cheaper, fungible things like medkits. This ensures she has space for key items, reduces the chance that she will discard expensive weapons accidentally, and keeps them out of the way of the stuff she is likely to use or drop from the inventory.²

Without the need to move items around, and without needing to take much care to avoid messing things up, the inventory interface is pared down to the bare necessities. The player can, and need, only ever do two things with an item: use it or drop it. (When at a store, she can buy a new item; when at storage, move or sell one she already has.)

The holographic UI in Dead Space makes things fast and easy, intruding as little as possible on the game’s intense atmosphere. It looks cool, fits the fiction, and it supports the player’s tasks and the aesthetic goals of the game: mainly, being scary.
