Sci-Fi UI Kit: Holo UI | 724 GUI Prefabs, HUD & Mobile

Holo UI contains 724 prefabs built from 2,525 sprites, plus 69 demo scenes and a launcher.

It is a complete holographic interface for a sci-fi game, made for Unity UI (uGUI) and TextMeshPro: glass panels, neon edges and targeting brackets in one consistent style, from the title screen to the results screen. Every demo scene is a working screen you can open, press Play on, and copy from, so you start from a finished layout instead of a sprite sheet.

Menus and meta-game, already laid out. 33 landscape scenes cover the title screen, loading, main menu, pause, four settings pages, campaign map, mission briefing, operative select, hangar, loadout, inventory, store, currency store, battle pass, daily rewards, skill tree, crafting, profile, rankings, squad lobby, achievements, inbox, world map, dialogue with choices, a hacking terminal, a confirm dialog, victory, defeat, level up and reward screens. The launcher lists all 69 scenes and opens any of them in one click, once Tools > Holo UI has added them to the Build Settings.

Seven genre HUDs. Shooter, space combat, racing, RPG boss fight, survival, flight and strategy, plus scoreboard, respawn, tutorial overlay and notification scenes. Compass strip, radar minimap, kill feed, segmented shield and health bars, ammo counter, ability cooldowns, lock-on brackets, speed and altitude tapes, a boss bar, party frames and a command grid are all in there.

Portrait mobile screens. 16 portrait scenes at 1080 x 1920: home, shop, battle pass, daily login, quests, offers, chat, inventory, rankings, level select, profile, settings, results, upgrade, loading and a touch HUD with a virtual joystick. Eight of them share a bottom navigation bar, and all 16 carry a safe-area component that keeps them clear of notches and home indicators.

724 prefabs. 19 button styles with normal, hover, pressed and disabled sprites and a selected state for gamepad and keyboard navigation; nine-sliced panels, frames and bars that resize to any layout; sliders, toggles, checkboxes, radios, input fields, dropdowns, scroll views and option selectors as wired uGUI controls; labels and badges; HUD widgets, 17 crosshairs, a hit marker and world markers; and 12 ready popups (confirm, info, warning, error, rename, purchase, rewards, quick settings, pause, item card, reconnecting and rating). The 19 button styles, 18 panels, 13 bars, 9 controls, 12 labels, 12 popups and 16 HUD widgets (spinners included) come in all seven colourways; the crosshairs, markers, six scene popups and the notification badge come in one.

Seven colourways. Cyan, magenta, amber, lime, crimson and violet are pre-rendered for every tinted sprite, so each colour keeps its glass and glow. The white set is made for tinting to your own colour.

It moves. 20 runtime scripts come with it, and the prefabs and scenes already use 17 of them: bars with a damage trail, radial cooldowns, rolling counters, typewriter text, hologram flicker, pulses and spinners, open and close transitions for popups, toasts, option selectors and a dynamic crosshair. A tab strip and a world-space marker (follows a 3D target and pins an off-screen arrow to the screen edge) are ready to add to your own screens. Tweens, bars, popups, toasts and text effects run on unscaled time, so menus keep animating while the game is paused.

Sharp at any size. Sprites are rendered at 2x and imported at 200 pixels per unit. 172 pictogram icons and 86 full-colour item icons (weapons, gear, consumables, ammo, currency, crafting materials, keycards, chests and rewards) come at 128, 256 and 512 px, with six rarity frames. Every sprite also ships as an editable SVG source.

Drop in and press Play. Works with the legacy Input Manager or the Input System, in the Built-in Render Pipeline, URP and HDRP. Three open-licence fonts come as TextMeshPro assets, with a PDF manual.
