Combat Arena PC Controls — Keyboard & Mouse
PC is the preferred platform for competitive Combat Arena players who want maximum aim precision. Atomic Horizon's Roblox FPS supports full keyboard and mouse input with customizable keybinds, adjustable sensitivity, and the responsiveness needed for slide-jump movement tech. This guide covers default bindings, recommended settings, and advanced tips for dominating Free for All lobbies and Team Deathmatch on desktop.
Default PC Keybinds
Combat Arena ships with standard FPS keybinds familiar to anyone who has played Call of Duty or similar titles on PC. You can remap most keys in the settings menu under Controls. The table below reflects default bindings — adjust them based on personal preference and hand size.
| Action | Default Key | Notes |
|---|---|---|
| Move Forward | W | Hold for sprint when shift is not toggled |
| Move Backward | S | Use for retreating during reload |
| Strafe Left | A | Combine with slide-jump for zigzag movement |
| Strafe Right | D | Strafe during ADS duels at mid-range |
| Jump | Space | Time with slide end for slide-jump tech |
| Slide | C or Ctrl | Varies by settings — bind to an easy pinky key |
| Sprint | Left Shift | Enable toggle sprint in settings |
| Fire | Left Mouse | Primary attack for all weapons |
| Aim / ADS | Right Mouse | Hold for precision with M4A1 and snipers |
| Reload | R | Reload behind cover — vulnerable during animation |
| Swap Weapon | 1 / 2 or Scroll | Quick swap to secondary in emergencies |
| Grenade | G | Remap closer to WASD for faster access |
| Melee | V or Mouse 4 | Finish low-health targets to save ammo |
Mouse Sensitivity Settings
Sensitivity is the most personal PC setting in Combat Arena. Too high and your crosshair overshoots MP5 rushers at close range. Too low and tracking enemies across open maps feels sluggish. Start around 800 DPI with an in-game sensitivity between 0.3 and 0.6, then adjust until you can comfortably flick 90 degrees and immediately re-acquire targets.
- Disable mouse acceleration in Windows for consistent aim.
- Use the same cm/360 measurement across all Roblox FPS games you play.
- Lower sensitivity for sniper sessions; slightly higher for SMG-only FFA grinding.
- Convert settings from other games using our sensitivity calculator.
- Test changes over at least five matches before deciding they feel wrong.
PC players face mobile and console opponents in cross-platform lobbies. Your precision advantage only matters if settings feel natural during high-pressure moments like the final kills in a 74–73 FFA race to 75.
Slide-Jump on Keyboard
The slide-jump is Combat Arena's defining movement skill, and PC players execute it most consistently thanks to simultaneous key inputs. Sprint with W and Shift, press your slide key (C or Ctrl) while holding forward, then hit Space at the slide's end to burst forward with maintained velocity. Bind slide to a key your pinky reaches without leaving WASD.
- Bind slide to C if Ctrl feels awkward with crouch on other games.
- Enable auto-sprint so Shift is not required during every slide-jump chain.
- Practice in an empty lobby or low-stakes TDM before ranked play.
- Combine slide-jump with strafe keys to peek corners unpredictably.
- Use slide-jump to close distance before switching to your MP5 in close quarters.
Advanced movement techniques including wall jumps and bunny-hop chains are covered in our movement guide. PC hardware allows the fastest execution of these techs, giving desktop players a movement ceiling higher than touch or controller input.
Recommended PC Keybind Layouts
Standard FPS Layout
Keep defaults if you migrate from other shooters. WASD movement, Space jump, C slide, G grenade, and mouse buttons for fire/ADS. This layout requires zero relearning and lets you focus on Combat Arena's unique mechanics instead of muscle memory conflicts.
Aggressive Rusher Layout
Move slide to Left Shift (with toggle sprint on Caps Lock), bind grenade to Mouse 4, and put melee on V. This keeps every offensive tool near your movement keys for SMG rush playstyles that dominate FFA. Pair with the MP5 from our SMG tier list for maximum effectiveness.
PC Graphics and Input Settings
Smooth frame rates matter as much as keybinds. Roblox FPS performance varies by hardware, but lowering unnecessary graphics settings reduces input lag during firefights. Cap your frame rate slightly above your monitor refresh if Roblox allows it, and close background applications that cause micro-stutters during slide-jump inputs.
- Play in fullscreen or borderless windowed for consistent mouse capture.
- Use the Roblox desktop app rather than browser for better stability.
- Increase FOV if the setting is available — wider view helps track flankers.
- Disable VSync if you notice input delay on mouse clicks.
- Use a large cloth mousepad for low-sensitivity arm aiming.
PC Loadout and Mode Tips
PC controls shine with precision weapons. The M4A1 starter assault rifle rewards tap-firing with mouse clicks at medium range in TDM. SMGs like the MP5 reward tracking with steady mouse movement during full-auto sprays. Snipers demand the lowest sensitivity settings — adjust per weapon class in your loadout rather than using one sensitivity for everything.
For mode-specific strategy, FFA on PC is about flick accuracy and spawn control to reach 75 kills first. TDM rewards holding angles with ADS and communicating with squadmates through external voice chat. Review FFA and TDM guides alongside this controls page for complete match preparation.
