an EP by shiftBacktick

Welcome to Alpha Periphery

Today you awoke from cryogenic sleep.

The exosuit that protects you greets you: Welcome to Alpha Periphery. You were hired by the system's licensed corporation as a surveyor to assess its value. As you walk the shifting desert beneath you, it becomes clear there are more mysteries than rare metals to uncover.

This is your strangest job yet.

System Requirements

Periphery Synthetic EP is best experienced with headphones and a gamepad.

Real-time synthesis is an extremely CPU-intensive process. It will attempt to run on any machine that meets its minimum requirements; however, surveyors may experience stuttering or drop-outs when running below the recommended requirements.

Minimum System Requirements

CPU SSE2 capable (64-bit)
RAM 2 GB

Recommended System Requirements

CPU 3.5 GHz Quad-Core (64-bit)
RAM 4 GB
GPU WebGL2 compatible

Browser Support

The HTML5 build of Periphery Synthetic EP is intended to be played in a recent version of a Chromium-based browser, such as Google Chrome, Microsoft Edge, or Opera. Browser extensions that alter page behavior are not recommended. Other browsers must support modern JavaScript features, the current Web Audio API specification, and WebGL2.

Troubleshooting Performance Issues

Periphery Synthetic EP has been optimized for its recommended system requirements. Surveyors experiencing performance issues are encouraged to adjust settings on the Audio or Graphics screens. Audio stuttering can be improved by deactivating reverb. Frame rates can be improved by reducing draw distance or deactivating graphics entirely.

How to Play

Surveyors pilot a versatile exosuit capable of traversing the most extreme terrain in the galaxy. It comes preinstalled with a terrain scanner and limited cargo space. Scan the terrain and collect its bounties.

The exosuit is also equipped with a printer that can synthesize raw materials into new and improved components. For example, with the Wheels upgrade, it can transform seamlessly between bipedal and wheeled modes to handle unique demands.

Conveniently, these worlds are covered with free elements. Collect and synthesize them to customize your exosuit. A fully upgraded exosuit can overcome any obstacle.

Movement

In its default bipedal mode, the exosuit grants surveyors full freedom of movement, with forward, reverse, turning, and strafing controls. It can jump in any direction, or bunny hop continuously, by pressing or holding the Jump control, in combination with other movement controls.

Surveyors will eventually desire new and improved abilities. These can be synthesized from the Upgrades screen.

Wheels

When installed, pressing the Transform control toggles its wheeled mode. While driving, the exosuit gains a substantial speed boost at the expense of some freedoms, surrendering its ability to strafe and jump. However, its brakes can be temporarily suspended, to slide down slopes and perform tight turns, by holding the Drift control.

Scanning

By pressing the Scan Terrain control, surveyors can gain new insights into their surroundings. Use this regularly to add new journal entries and fast travel destinations to the Codex.

Terrain Sonification

Many worlds have atmospheric features which obstruct visibility. With the scanner, surveyors can also visualize local elevation differences, and collectible objects, with sound.

Scan results are represented as streams of tones. These extend outward to form a 200-meter semicircle ahead. Level terrain is carefully tuned to Middle C, with each octave corresponding to 100 meters of difference. Nearby objects emit brighter pings.

Materials

Materials are collectible objects which spawn in clusters. They are grouped into four categories with unique sounds and uses. To collect them, surveyors must get close and have available cargo space.

Surveyors can inspect their inventory from the Materials screen. Each material type has a maximum capacity independent from one another. They can increase their material capacity with the Cargo Racks upgrade.

Synthesis

Surveyors are alerted whenever they have enough materials to synthesize a new upgrade for their exosuits. From the Synthesis screen, they can browse their inventory and available upgrades.

Controls

The exosuit supports a variety of input devices. Although remapping of controls is currently not available, alternate control schemes have been provided where appropriate.

Keyboard Controls

The exosuit's keyboard controls support play with one or both hands:

Action Key 1 Key 2 Key 3
Forward W Up Arrow Numpad 8
Reverse S Down Arrow Numpad 5
Turn Left Q Left Arrow Numpad 7
Turn Right E Right Arrow Numpad 9
Strafe Left A Numpad 4
Strafe Right D Numpad 6
Jump Space Numpad 0
Drift Left Control Right Control
Sprint / Turbo Left Shift Right Shift
Transform R V
Scan Terrain F
Confirm Enter Space
Back Escape Backspace

Access Hotkeys

Hotkeys have been provided to quickly jump to screen elements. Press numbers 1 through 0 to focus the element at that position. If the desired element is already focused, then it will be clicked instead.

Additional keyboard shortcuts have been provided to quickly access certain UI elements with a screen reader while in-game. They can be used by first pressing and holding either Alt key:

Action Button
Coordinates 1
Heading 2
Velocity 3
X-Coordinate X
Y-Coordinate Y
Z-Coordinate Z

Mouse Controls

The exosuit can be controlled with a mouse in tandem with a keyboard for an immersive first-person experience:

Action Button
Turning Mouse X-Axis
Vertical Look Mouse Y-Axis

Gamepad Controls

The exosuit supports standard gamepads such as an Xbox controller. Other controllers can be configured with a utility like x360ce:

Action Button 1 Button 2
Forward Left Stick Right Trigger
Reverse Left Stick Left Trigger
Turning Right Stick
Strafing Left Stick
Jump Right Bumper
Drift Left Bumper
Sprint / Turbo Press Left Stick
Transform Press Right Stick
Sonify Terrain A
Vertical Look Right Stick
Confirm A
Back B
Open Game Menu Start
Open Codex Select

Haptic Feedback

Feel the exosuit as it interrogates the terrain. Vibration can be reduced or removed entirely from the Controls screen.

Touch Controls

Periphery Synthetic EP does not currently support touch beyond its menus. For best results on mobile devices, a gamepad is strongly recommended.

Accessibility

Periphery Synthetic EP is developed in accordance with WCAG (Web Content Accessibility Guidelines) 2.1 at Level AA conformance. Its menus are fully operable with a keyboard and screen readers such as NVDA.

Photosensitivity Warning

The exosuit can produce certain strobing patterns when moving at high velocities. Please navigate to the Graphics screen to make adjustments or deactivate them entirely.
