Controls and Settings#
[Atomfall](https://ntgame.com/atomfall/) is an action game weighted toward stealth and survival planning, and your keybindings directly affect your survival rate in the Windscale quarantine zone. Beyond a bindings overview, the real point of this page is the judgments behind each action — when to crouch, when to reload, and how carry weight and radiation change the way you operate. Because this game has no convenient “one-button win” inputs, most failures come from habits of operation rather than insufficient numbers.
Bindings Overview#
Below is a standard mapping centered on PC keyboard and mouse. Note that the game allows rebinding in settings, so treat this as a reference baseline rather than something to memorize.
| Action | Key | Notes |
|---|---|---|
| Move | W / A / S / D | Movement in all directions |
| Interact | E | Talk, pick up, open doors, search containers and bodies |
| Melee attack | Left mouse button | Swing the current melee weapon |
| Fire firearm | Left mouse button | Fire the current gun |
| Aim | Right mouse button (hold) | Raise iron sights or enter aiming stance |
| Sneak | Ctrl (hold) | Crouched movement; lowers the chance of detection |
| Jump | Space | Cross low walls, ditches, and other obstacles |
| Sprint | Shift (hold) | Run at full speed; continuously drains stamina |
| Reload | R | Load ammo into the held firearm |
| Inventory | Tab | Open the bag, equipment, and item management |
| Map | M | Open the area map to view discovered locations |
| Quick-use item | Number keys 1-4 | Matches the item in the corresponding quick slot |
| Pause menu | Esc | Pause and enter the system menu |
Controller players can map the same functions to sticks and triggers in settings, with logic identical to keyboard and mouse. Since habits differ widely, we won’t mandate a specific controller layout — the key is understanding the mechanics below, then arranging your own bindings around them.
Mechanics Unique to This Game#
Sneaking and Backstabs#
The core criterion of stealth here is your visibility and noise while crouched, not simply “hiding.”
- Holding the sneak key to stay crouched slows your movement but clearly lowers the chance of being spotted by distant enemies.
- Approaching directly from behind an enemy and striking kills most human enemies outright. Whether you’re “behind” someone reads from their current facing, not the map compass; enemies are least mobile while turning during a patrol, which is the ideal backstab window.
- Bodies are the biggest exposure risk. After downing an enemy, if the body lands within another enemy’s line of sight, it triggers alertness.
Aiming, Shooting, and Reload Timing#
- Holding aim enters iron sights: the reticle visibly tightens and hits cluster better; but aiming slows your movement, which backfires when an enemy closes in at short range.
- Reloading is a hard “standing still” duration that eats the time you need to watch enemies. So reload behind cover or after confirming the enemy has lost track of you — never press reload in an enemy’s face.
- Gunfire makes noise and exposes your position. A single shot in a quiet environment can pull every enemy in a nearby camp toward you — weigh this in advance on any stealth route.
Carry Weight, Stamina, and Mobility#
- This game has a carry-weight system. Excess weight significantly lowers movement speed and stamina recovery, directly hurting your ability to dodge and retreat.
- More carrying capacity is therefore not always better. Before entering a high-value zone, clear redundant items and get weight down to where you can sprint normally.
- Sprinting and close-range dodging both drain stamina, and when stamina bottoms out you can neither run nor dodge — the single most important state to avoid operationally.
Survival Status Management#
- The game tracks three conditions — radiation, hunger, and health — and each directly affects whether you can operate normally.
- Radiation keeps accumulating and suppresses your condition caps, so take rad pills before entering high-radiation areas rather than scrambling once the bar warns you.
- Hunger and low health both inflict real penalties on movement and combat, so keeping food and medical supplies in your bag at all times is more practical than carrying an extra weapon.
- Status indicators usually sit on the HUD; glancing at the bars as you pass avoids having a negative status suddenly interrupt your rhythm in a key fight.
Crafting and Workbench Interaction#
- Tools, weapons, and consumables mostly need to be crafted at a workbench, not conjured from nothing.
- Before crafting, confirm you have enough materials on hand, then decide whether to “make a better weapon” or first “repair the durability of existing equipment.” Low durability degrades your attacks and is a major factor in how combat feels.
- Pin frequently used consumables to quick slots so you can press the matching key in combat, instead of repeatedly opening the bag and breaking your flow.
A Typical Stealth Operation Sequence#
Turning the criteria above into executable steps, using a courtyard guarded by patrolling enemies as the example:
- Observe before acting: crouch outside the courtyard and read the guards’ patrol routes, facings, and numbers to find the blind spots.
- Mark your targets: memorize each guard’s stops and turning moments, and prioritize the one who is isolated and facing away.
- Deal with them one by one: circle behind a target, land the backstab, then immediately drag the body into shadow so no other guard’s gaze sweeps over it.
- Control noise: never fire inside the courtyard. If you must shoot, first lure the other guards away with a thrown object, then quickly finish the isolated one.
- Keep an exit open: before entering, confirm your weight isn’t ruining your sprint, and stock rad pills and medical supplies in case the guards get alerted and you need to escape.
- Sweep after clearing: search every crate once the courtyard is empty, then check your own condition — restore everything before moving to the next area.
This sequence relies on no specific equipment; it is the universal method for stealth in this game, and rehearsing it drops your error rate noticeably.
Common Mistakes and Fixes#
| Mistake | Consequence | Correct Approach |
|---|---|---|
| Reloading in front of enemies | Focused down during the reload window | Get behind cover or confirm the target is lost first |
| Charging into a high-value zone at full weight | Movement and stamina recovery collapse | Clear redundant items before entering and control your weight |
| Sneaking into an enemy’s sight and then firing | One gunshot ignites an entire camp’s alertness | Read patrol facings and spread first, then decide fight or detour |
| Taking rad pills only when the bar warns | Caps already suppressed, operation restricted | Take the medicine before entering a high-radiation zone |
| Thinking about repairs only when durability bottoms out | Weaker attacks, disrupted combat rhythm | Stop by the workbench mid-task for maintenance and materials |
Settings Adjustments Worth Making#
- Key bindings: put the most-used items and functions in comfortable spots (for example, pin common consumables to one row of number keys) to cut the number of bag openings that interrupt play.
- View settings: adjust field of view to your screen size and find the angle where surrounding threats are visible without targets becoming too small to hit — one that suits your habits.
- Audio: much of this game’s threat detection runs on sound (footsteps, gunfire, enemy chatter). Prioritize environmental clarity so stealth runs can locate enemies by ear rather than by walking into them.
- HUD information: keep status readouts (radiation, hunger, health, weight) permanently visible so you can judge when to restore condition instead of digging through menus.
- Difficulty: difficulty changes resources and enemy strength but not the operation logic. If you keep failing in the same zone, it’s usually not insufficient numbers — it’s habits (weight, reload timing, noise exposure) that need adjusting first.
Controller vs. Keyboard and Mouse#
Combat and stealth each favor different inputs in different situations; neither is absolutely superior.
- Keyboard and mouse is more precise for aiming and iron sights, suiting routes that lean on firearms and ranged clearing; it’s also quicker for browsing the map and inventory when the bag is full of clutter.
- Controller has a natural edge in melee combos and the fluidity of crouched movement, with feedback closer to an action game’s feel — ideal for players who prefer melee backstabs and stealth.
Whichever input you pick, the core is putting the criteria above into practice: control weight, manage condition, and time your reloads and shots. Build those habits, and your movement through the quarantine zone becomes noticeably steadier.
