Design the Perfect FPS UI for Your Roblox Game
A first-person shooter UI is minimal and readable under pressure: ammo, health, armor, crosshair, and a kill feed.
FPS UI has one job: not get in the way. Players are tracking moving targets, flicking their crosshair, and managing reloads all at once. Every element on screen competes for attention, so the HUD has to be small, high-contrast, and glued to the screen edges. This guide covers the layout rules, the crosshair, the ammo and health readouts, and the kill feed that makes a Roblox FPS feel like a real shooter.
Design requirements
- • Low-clutter corners for health and ammo
- • Center crosshair that does not obstruct targets
- • Kill feed with fade-out entries
- • Hitmarker feedback on successful shots
- • Scales for 16:9 and ultrawide without stretching
- • Low-health screen vignette for tension
Step-by-step tutorial
- 1
Layout the HUD corners
Anchor health bottom-left, ammo bottom-right, minimap top-right, and kill feed top-left. Keep each cluster under 200x80 logical pixels so it does not eat the viewport.
- 2
Add the crosshair
Use a small Frame or ImageLabel anchored to the exact screen center with AnchorPoint (0.5, 0.5). Four thin lines or a single cross image works; keep the gap in the middle clear.

Build the ammo counter
Show magazine and reserve counts with a monospace font. Color the counter red when magazine is below 25% so players know to reload.
- 4
Wire the health bar
Bind Humanoid.HealthChanged to a TweenService fill animation. Add a red screen vignette (a full-screen ImageLabel with low transparency) when health drops below 30%.
- 5
Add the kill feed
Use a UIListLayout anchored top-left. Each kill entry is a small Frame that fades out after 4 seconds using TweenService. Cap the list at 5 entries.
- 6
Add hitmarkers
On a successful hit, flash a small cross or X at the crosshair for 100 milliseconds. Play a short UI sound for audio feedback.
Crosshair design: the center must stay clear
The crosshair is the most-clicked pixel in an FPS. If it is too thick, it hides the target. If it is too thin, players lose it against bright backgrounds. Four lines with a 4 to 6 pixel gap in the center is the standard because the gap lets you see exactly where the shot lands. Anchor the crosshair to the screen center with AnchorPoint (0.5, 0.5) and use Scale sizing so it stays centered on any aspect ratio. Avoid animated crosshairs that expand on movement - they look cool but they add noise during aim.
Ammo counters that read at a glance
Players check ammo mid-fight, so the counter has to be readable in under half a second. Use a monospace font (RobotoMono or Code) so digits do not shift width as they change. Show magazine over reserve, large over small, so '30 / 90' reads top-to-bottom. Color-code the state: white at full, yellow at half, red at the last 25%. When the magazine hits zero, flash the counter once and show a 'RELOAD' prompt below it. Do not auto-reload for the player - it breaks muscle memory.
Health bars and low-health feedback
A flat health bar is not enough in an FPS. You need three layers: the bar itself (a Frame that fills based on Humanoid.Health / MaxHealth), a damage flash (a brief white overlay when damage is taken), and a low-health vignette (a red full-screen ImageLabel at 60 to 80 percent transparency that fades in below 30% health). Bind the bar to Humanoid.HealthChanged and use TweenService with a 0.15-second animation so the bar drains smoothly instead of snapping. The vignette creates urgency without blocking the view.
Kill feeds that do not clutter
The kill feed goes top-left, opposite the minimap. Each entry shows the killer name, a weapon icon, and the victim name. Use a UIListLayout that adds new entries at the top and pushes old ones down. Each entry auto-destroys after 4 seconds with a fade-out TweenService animation. Cap the list at 5 entries so a multi-kill does not fill the screen. Keep entry height at 24 to 28 logical pixels - small enough to stay out of the way, large enough to read.
Design tips
- • Keep HUD elements under 10% of total screen area - anything more blocks targets.
- • Use high-contrast colors: white or yellow text on dark backgrounds, not mid-gray on gray.
- • Bind hitmarkers to both visual flash and audio - players react faster to sound than sight.
- • Test the HUD at 16:9, 21:9, and 4:3 aspect ratios in the editor's device preview.
