Warhammer 40K Space Marine 2 Keyboard Controls: What to Know First
Warhammer 40K Space Marine 2 keyboard controls cover movement, melee combat, ranged combat, class abilities, and squad actions across a fully rebindable PC input system. Developed by Saber Interactive and published by Focus Entertainment, Space Marine 2 launched on PC (Steam), PS5, and Xbox Series X/S in September 2024. The game supports keyboard and mouse on PC with full rebinding, and controllers via preset layouts on all platforms.
The combat system in Space Marine 2 demands six to seven distinct inputs in tight sequence: shoot, melee, parry, dodge, execute, throw equipment, and activate a class ability. The default keyboard layout puts that load almost entirely on the left hand, which is why rebinding is the first thing experienced PC players address after launch.
Stat: Space Marine 2 sold over 4.5 million copies in its first two weeks, making it the best-selling Focus Entertainment title of all time. A significant share of that player base reported the default parry key (C) as the first control they changed.
Space Marine 2 PC Keybinds: Default Keyboard and Mouse Layout
The Space Marine 2 PC keybinds below reflect the default layout. Movement uses standard WASD, combat runs across the mouse buttons and nearby keys, and communication actions sit on the function-adjacent row.
Space Marine 2 Movement Keybinds
| Action | Default Key |
|---|---|
| Move Forward | W |
| Move Backward | S |
| Strafe Left | A |
| Strafe Right | D |
| Sprint | Left Shift |
| Dodge | Space |
Sprint activation toggles between Hold and Toggle in settings. Hold sprint prevents unintended animation locks during parry and execute sequences, which is the recommended setting for new players learning the combat rhythm.
Space Marine 2 Combat Hotkeys
| Action | Default Key |
|---|---|
| Fire / Gun Strike | Left Mouse Button |
| Melee Attack | Right Mouse Button |
| Parry / Block | C |
| Finisher / Interact | E |
| Aim / Zoom / Heavy Stance | Middle Mouse Button |
| Zoom In / Alt Fire | Mouse Wheel Up |
| Zoom Out / Alt Fire | Mouse Wheel Down |
| Lock on Target | X |
| Switch Weapon | V |
| Primary Weapon | 2 |
| Secondary Weapon | 1 |
| Reload | R |
| Use Class Ability | Q |
| Use Medicae Stimms | F |
| Use Equipment | G |
Space Marine 2 Communication and UI Hotkeys
| Action | Default Key |
|---|---|
| Focus Attention / Social Wheel | T |
| Scoreboard | Tab |
| Open Text Chat | O |
| Voice Chat | Z |
Important: The E key handles both Interact and Finisher by default. The game decides which action applies based on context: if an enemy is in executable state, E triggers the finisher; if you stand near a door or objective, E triggers the interaction. After rebinding either action to a new key, test both contexts separately to confirm neither was left unassigned.
Space Marine 2 Parry Keybind: The Most Important Change on PC
The default Space Marine 2 parry keybind is C. While reachable, C sits far from the WASD cluster and requires either stretching the left pinky or briefly interrupting movement input. Parry windows in Space Marine 2 are tight, typically requiring a reaction to a blue enemy attack flash within a fraction of a second. A misplaced finger during that window means a stagger or death.
The community consensus for better Space Marine 2 keybind setups points to these alternatives:
| Parry Replacement | Notes |
|---|---|
| Mouse Button 4 (rear thumb button) | Best option for most gaming mice; keeps both hands on their primary tasks |
| Mouse Button 5 (forward thumb button) | Works well if MB4 is already assigned to Focus Attention |
| Left Ctrl | Familiar from other games; works without a gaming mouse |
| B | Easy to remember as “Block”; keeps the left hand in a natural spread |
Pro Tip: If your mouse side buttons do not register in-game, bind the thumb button to a keyboard key inside your mouse software (Logitech G Hub, Razer Synapse, SteelSeries GG, etc.), then assign that keyboard key in the Space Marine 2 controls menu. This two-step method works reliably when native mouse button detection fails.
Space Marine 2 Dodge Mechanic: One Key, Two Outcomes
The Space Marine 2 dodge hotkey is Space by default, but pressing it once and pressing it twice produce different results. A single press performs a short sidestep or step-back that repositions your character slightly. A double-tap of Space executes a full roll that covers noticeably more ground.
The roll covers enough distance to clear most projectile hitboxes from bosses such as Neurothrope or Imurah. Building the habit of double-tapping Space when facing ranged attacks or area-of-effect abilities pays off in higher Operations difficulty tiers where a single failed dodge ends a mission.
Space Marine 2 Controller Layout: PS5 and Xbox
Space Marine 2 controller keybinds place shooting on triggers, melee defense on bumpers, and mobility on face buttons. The controller layout reflects the original design intent more closely than keyboard and mouse, which multiple players and reviewers noted felt like a port of a controller scheme rather than a native PC input system.

Stat: Space Marine 2 offers seven preset controller layouts rather than full per-button remapping on consoles. Players who need a custom layout beyond those presets must use platform-level tools: PlayStation accessibility button assignments, Xbox Accessories app, or Steam controller configuration on PC.
Space Marine 2 Platform Controls Summary
| Platform | Input Method | Rebind Options |
|---|---|---|
| PC (Steam) | Keyboard and Mouse | Full per-key rebinding in Controls menu |
| PC (Steam) | Controller (Xbox / PS5) | Seven preset layouts; no per-button in-game remapping |
| PS5 | DualSense controller | Preset layouts; PlayStation system accessibility assignments |
| Xbox Series X/S | Xbox controller | Preset layouts; Xbox Accessories app for deeper remapping |
How to Rebind Space Marine 2 Keyboard Controls
Space Marine 2 keybind remapping on PC lives under Settings > Controls. Click any action, press the new key or mouse button, and the binding saves immediately. Pressing no key or Escape cancels the rebind attempt. To reset a changed binding to its default, use the Reset option next to that specific action.
One common confusion involves the Aim / Zoom / Heavy Stance entry. The game labels this binding as “Heavy Stance” rather than “Aim,” which leads many players to miss it when looking for an aim rebind. The Middle Mouse Button default for this action is the one to reassign if you want aim on a more natural input.
Pro Tip: Set Sprint to Hold rather than Toggle before your first serious Operations mission. Toggle sprint can fire unintentionally during parry or execute animations and briefly locks your character in a sprint state, preventing an immediate parry input when a blue attack flash appears.
Space Marine 2 Best Keybind Setup by Playstyle
| Playstyle | Priority Rebind | Reason |
|---|---|---|
| Melee-heavy (Assault, Bulwark) | Parry to MB4 or Left Ctrl | Parry windows are too tight for C under pressure |
| Ranged (Tactical, Sniper, Heavy) | Aim to Hold mode | Drops aim instantly to dodge or parry red attacks |
| Bulwark (shield class) | Keep melee and block on separate fingers | Shield class asks for both inputs in close sequence |
| Controller PvE | Default preset | Combat hints align with the bumper-and-trigger design |
| Accessibility needs | Platform-level remapping | Covers reach limitations; note that button prompts may not match |
FAQ
What are the default Space Marine 2 keyboard controls for movement?
The default Space Marine 2 movement keys are W (forward), S (backward), A (strafe left), and D (strafe right). Left Shift sprints and Space dodges. A single press of Space performs a step-back or sidestep, while a double-tap executes a full dodge roll.
What is the best parry keybind in Space Marine 2 on PC?
The most recommended Space Marine 2 parry keybind is Mouse Button 4 (the rear side button on gaming mice). This keeps the left hand on WASD and lets the thumb handle parry without any finger repositioning. Left Ctrl and Mouse Button 5 are strong alternatives. The default C key works but sits far enough from WASD that reaction parries under pressure become inconsistent.
How do I rebind controls in Space Marine 2?
Go to Settings > Controls in the main menu or pause menu. Click the action you want to change and press the new key. To reset a keybind to its default, select the reset option next to that action. Note that “Aim” in Space Marine 2 appears in the menu as “Heavy Stance” rather than “Aim,” which is the binding to change for mouse-button aim remapping.
Does Space Marine 2 have full controller remapping on PS5 and Xbox?
No. Space Marine 2 offers seven preset controller layouts on PS5 and Xbox but does not support full per-button controller remapping in-game. Players who need a custom layout beyond the presets should use PlayStation’s system accessibility button assignments, the Xbox Accessories app, or Steam controller configuration when playing on PC.
What does pressing Space twice do in Space Marine 2?
Pressing Space once performs a short dodge step. Pressing Space twice in quick succession performs a full dodge roll that covers significantly more distance. The roll clears most projectile attacks and boss area-of-effect abilities that the step-back does not escape.
Can I play Space Marine 2 effectively on keyboard and mouse?
Yes, but the default layout concentrates too many combat actions on the left hand. Moving parry off C, assigning aim to a comfortable mode (Hold or Toggle), and separating execute and interact into distinct muscle-memory positions makes the keyboard and mouse experience competitive with controller play.
What key activates the class ability in Space Marine 2?
The default Space Marine 2 class ability hotkey is Q. Every class uses Q for its unique ability, from the Assault’s jump pack to the Bulwark’s battle cry to the Heavy’s iron halo. Q saves lives consistently across all classes and is one of the first keybinds worth reinforcing through deliberate practice.
