Alien Invasyndrome Controller and Gamepad Support

The honest status

Alien Invasyndrome ships mouse + keyboard as the primary input. The Steam Demo (app 4830300, store date 24 July 2026) does not advertise first-party gamepad support, but the input layer is exposed through Steam Input, which means community controller profiles are workable for the standard stealth verbs. As of the 24 August 2026 wiki re-check, the menu prompts, softlock enter / exit verb, and skill screen all still render keyboard-first on English Windows.

Developer Mozu Field / 百舌鳥, publisher Shady Corner Games, full game Steam app 4603980 still TBA. Adult 18+. Hub: Controls Hub. Sibling: Keyboard Controls, Stealth Actions, Pause Menu, Performance & Settings.

What works on a controller today

Concretely, when you wire a gamepad through Steam Input with a generic community profile:

• Movement (left stick): works. The larva moves in 8-way grid steps. Not as precise as WASD for tight Kitchen timing, but usable.
• Camera nudges (right stick): works. Cursor or aim nudges that the mouse normally handles get mapped to stick input. Slightly slower reaction time than a mouse.
• Commit / interact (face button): works if your Steam Input profile maps the gamepad south button to the keyboard Z / interact verb.
• Softlock enter / exit: works with stick + face button mapping, but the exit feel is not as crisp as a keyboard tap. You may feel the ~1 minute detection hide differently because of input latency.
• Skill screen and pause menu: navigable on a D-pad if your Steam Input layer maps arrow keys. The X-axis confirm action is typically the gamepad south button.

What does not work well:

• Direction-precise targeting (the kind you need when tapping a softlock direction during a tight spot). Mouse precision beats stick precision; expect to retry those micro-decisions more often.
• Quick double-tap verbs like the unhide + sprint-out pattern. A keyboard can double-tap faster than most gamepad profiles can chain face-button presses.
• Pause → reload → resume. Pause on gamepad is reliable; save loading from pause was unimplemented in earlier builds — that is true regardless of input device. See Save & Progress.

Steam Input is the supported path

Steam Input is Valve’s official middleware that translates gamepad input into whatever the underlying game expects. For Alien Invasyndrome, that means you map your gamepad to a virtual mouse + virtual keyboard. Two ways:

1. Use a community profile. Search the Steam Input community profiles for the Demo app. The community has posted workable XInput bindings for Xbox, DualShock 4, DualSense, and Switch Pro controllers. Pick the most-recent one and verify it against the in-game verb list.
2. Build your own profile. Open Big Picture Mode → Demo → Manage Game → Controller Configuration. Map left stick to WASD, right stick to mouse, face buttons to interact verbs, triggers to softlock verbs, and bumpers to skill / pause.

Whichever path you take, test the profile in a low-pressure room first (Kitchen doorway scout) before trusting it on a Security attempt.

What the Demo does not offer

• No official first-party controller support at the time of the August 2026 wiki check.
• No button re-skin in-game. On-screen prompts show keyboard letters, not face-button glyphs, regardless of what Steam Input is doing underneath.
• No aim assist or gamepad-specific stickiness. The Demo’s cursor logic is mouse-native, so a gamepad stick will feel slightly different from a typical pad-first game.
• No console controller presets. The Demo was published as a Windows title, so Xbox / PlayStation presets on the platform level are not built in. Steam Input fills that gap but is not a publisher guarantee.

PlayStation, Xbox, and Switch controllers

All three families work with Steam Input on Windows. Realistic caveats:

• Xbox controllers: best-supported on Windows because XInput is the OS-level standard. Expect the least friction.
• PlayStation DualShock 4 / DualSense: works through Steam Input; you may need to enable PlayStation controller support in Steam settings. Haptics on DualSense is not exposed by the Demo.
• Switch Pro Controller: works through Steam Input with a community profile. The mapping is less polished than Xbox, but the standard stealth verbs are reachable.

If you are on Steam Deck, the controller is the Steam Controller by default and the same Steam Input layer applies. See the Steam Status page for Deck-class hardware guidance.

Gamepad versus keyboard for the Demo

A useful mental model:

• Mouse + keyboard wins for: tight spots, softlock exits, detection minute re-tries, skill screen experimentation. The Demo’s input verb design was clearly mouse + keyboard first.
• Gamepad wins for: casual playthroughs from a couch, relaxed exploration, accessibility for players who cannot or prefer not to use a mouse for long sessions.
• Speed-leaning play: keyboard wins. Gamepad adds input latency and reduces precise targeting.

For a first-time player, pick the input you are most comfortable with. The Demo does not punish input choice as long as you can hit the softlock exit verb within ~1 second of the detection timer ending.

What to test after binding your controller

Run a short regression drill before committing to a long session:

1. Move the larva with the left stick. Confirm 8-way grid stepping feels natural.
2. Nudge the cursor with the right stick. Confirm cursor precision is enough for the interact verb on furniture.
3. Trigger the softlock enter verb (mapped to a face button or trigger). Confirm you can enter the hide.
4. Wait the full ~1 minute using Detection Timer.
5. Trigger the softlock exit verb. Confirm exit is crisp.
6. Open the pause menu with the bound pause button. Confirm navigability with the D-pad.
7. Open the skill screen. Confirm you can read labels and spend points.

If any of those seven steps fail, your Steam Input profile is the problem, not the Demo. Re-map, retest, do not assume the Demo is broken.

What this page will not do

• Link unofficial pad-to-keyboard mapper binaries. They often ship malware and flag your Steam build as modified.
• Document console-specific tricks. The Demo is Windows-only and not announced for console ports.
• Predict when first-party controller support arrives. The full release is TBA; we will update this page when the developer announces input changes.

Bottom line

The Demo is mouse + keyboard first. Controllers work through Steam Input with a community or custom profile, and the standard stealth verbs (move, interact, softlock enter / exit, pause, skill screen) are reachable on Xbox, PlayStation, and Switch controllers. The Demo does not re-skin on-screen prompts to gamepad glyphs, and precise targeting still favors a mouse. For first-time players, pick the input you are most comfortable with; the Demo does not punish input choice as long as you can hit the softlock exit verb reliably.
