Star Citizen Update Alpha 4.5 Adds Much-Awaited Engineering Gameplay and More

Cloud Imperium Games released Update Alpha 4.5 of the growing space simulator Star Citizen, adding a highly-anticipated feature.

The update, which is now available on the live servers, includes the introduction of engineering, which is a vital component of the multi-crew promise of the game.

Basically, players will be able to monitior, repair, and replace components of their ship in flight, adding survivability. On the other hand, said components can also be targeted by enemies, for an additional layer of tactical gameplay.

The addition of Armor is a crucial part of this equation, with the resilience of a ship not just represented by hit points anymore, but by physical armor protecting its components and acting against weapons with different levels of armor penetration.

Further parts of this massive new gameplay features include firefighting, energy management, heat management, and more.

Interestingly, the update also adds an experimental implementation of VR gameplay, on top of improved graphics settings, and much more.

You can check out a trailer below.

Here are the patch notes.

Engineering Gameplay

Resource Network & Engineering Terminal

Ships now feature an engineering terminal providing comprehensive oversight of all ship systems through an interactive 3D schematic.

Interactive 3D ship schematic with rotatable view and zoom controls
Color-coded component health indicators:
Real-time room atmospheric conditions including oxygen levels and temperature Fire alert system with visual indicators and audio warnings
Door state visualization (open/closed status) with lock controls
Component search functionality for quick navigation
Armor health bar displaying overall hull integrity

Power Management System

Ships now operate on a finite power budget distributed from power plants across all major systems.

Power distribution controls for Shields, Weapons, Thrusters, and Life Support
Three capacitor types affecting system performance:
Weapon Capacitor: Affects weapon fire rate
Shield Capacitor: Affects shield regeneration speed
Thruster Capacitor: Affects boost capacity and recovery
Preset system allowing saved power configurations
Presets can be shared between players via local configuration files
Status warnings combine low power alerts with critical system warnings

Fuse & Relay System

Fuses are a vital part of the power pips system in most vehicles. When fuses fail, components lose power until replacements are installed.

Relay boxes distributed throughout ships (1-2 for small ships, 3-4+ for medium/large)
Damaged fuses visible on engineering screen and physically within relay boxes
Manual replacement required by accessing relay boxes and physically swapping fuses
Loss of all fuses in a relay causes power pip loss
Fuses now available at ship component shops

Component Repair and Replacement System

Damaged components can now be repaired during flight using the handheld repair tools with RMC (Repair Material Composite) attachment.

Point repair tool beam at damaged components to restore health
Multiple players can combine repair beams for faster restoration
Shops now sell fully-filled RMC canisters with New Cambio Lite SRT and Cambio SRT canisters available

Component health affects performance at various thresholds: 100-75% (full performance), 75-50% (minor degradation), 50-25% (significant reduction), 25-10% (severely impaired), 10-1% (critical), 0% (destroyed/non-functional).

Physical components can be removed and replaced during flight on physicalized ships.

Size 1-2 components replaceable in-flight via component access bays
Size 3+ components require docking at a station for replacement
Removed components transfer to player inventory or drop if inventory full
Non-physicalized ships use Vehicle Loadout Manager at stations

Fire Hazards

Dynamic fire propagation threatens ship integrity and crew safety, requiring active management.

Fires are triggered by component damage, overheating, electrical shorts, and external weapon ignition
Fire will propagate between connected rooms with realistic smoke generation
Fire extinguishers available aboard ships with limited charges that can be refilled by placing back onto their ship
Room venting removes oxygen to suppress fires (seal room first)
Life support filters smoke from atmosphere (processing time varies)

Heat Management

Thermal systems now play a critical role in ship operations.

Components generate heat during operation based on activity level
Coolers dissipate heat from weapons, thrusters, and other systems
Damaged coolers reduce heat dissipation proportionally to damage
Overheating triggers thermal shutdown until temperature normalizes
High operating temperatures accelerate component wear

Critical Systems & Self-Destruct

Power plant failure now has catastrophic consequences.

Power plants reaching 0% health have a chance to trigger a self-destruct countdown
The power plant will receive damage when ship hull goes critical with zero health
Critical power plants can be repaired with multi-tool to cancel countdown

Ship Armor and Shield System

Ships now feature an armor health pool that reduces incoming damage and weapon penetration.

Armor percentage modifies weapon penetration linearly (100% armor = no penetration, 0% = maximum)
Energy weapons deal more damage against armor while ballistic weapons send more damage through armor
Penetration uses cone-based checking affecting components within impact area
Penetration damage scales radially from hull impact point
Armor health bar added to engineering screen UI
Armor health slightly reduced across all ships for balance
Unique armor values for military variant differentiation

Loot Refresh & Collector Updates

Major redistribution of rare items across dungeon content with new exclusive rewards for each activity type.

Ore Refining Economic Balance

Refining of ores has undergone changes to a smaller volume of yield output (From ~85% to ~45%) while significantly increasing the refined sale price to compensate. Effectively, you can now transport more value of refined ore with smaller SCU space with this latest update.

The base prices of nearly all commodities have been significantly increased across the board. This affects all major brackets of sandbox commodities. (32/24s, 16s, 8s, and 2s). Price differences within brackets have been pressed closer together in order for dynamic pricing to better influence which goods are optimal.

Virtual Reality Support (Experimental)

Initial VR implementation allows players to experience Star Citizen in virtual reality. This feature is experimental and under active development.

Experience the entire Star Citizen universe in virtual reality, from the Main Menu to FPS gameplay to flying your ship and everything in between!

For more information on this experimental mode and further updates, check out our Spectrum thread to discuss this implementation.

Full VR headset support for gameplay
VR aim offsets for unlocked and slaved gimbals
Auto-recenter option for FPS aiming down sights
Dedicated VR graphics settings
Multiple VR-specific stability improvements

Note: VR support is experimental. Players may encounter performance issues and bugs not present in standard play.

VR Theater Mode

Toggle between full VR and Theater Mode at any time, giving you the best of both worlds. Theater Mode projects a virtual screen in your headset with full game compatibility using the standard desktop pipeline.

Love flying in VR but prefer traditional controls for FPS? Just press a button to instantly switch between full immersion and Theater Mode, complete with head tracking support. Theater Mode mirrors your desktop resolution, so you can even play in ultra-widescreen in VR without ever removing your headset.

VR Dynamic Switch

Let the engine handle the VR switch automatically. Whenever you put on the headset VR will be enabled on its own. If you take it off you are back in desktop mode!

Note that not all headsets support this at the moment.

Default Keybinds

Toggle VR on and off: “Numpad /”
Toggle Theater Mode on and off: “LALT + Numpad 5”
Recenter View: “Numpad 5”

All bindings can be customized under Advanced Controls/Keybinds → Comms, FOIP, VR & Headtracking.

VR specific settings

You will find a series of new settings in the options under Comms, FOIP, VR & Head Tracking. They will only show up when you have a VR headset connected:

VR – Enabled: Enables and disables the headset (also available via keybind)
VR – Theater Mode: Enables and disables Theater mode (also available via keybind)
VR – Theater Mode Scale and Distance: Allows you to adjust Theater mode to your liking.
VR – Automatic Switching: Automatically enables / disables VR based on headset detection if your headset supports it via a sensor (verified on Quest 3 – compatibility varies by headset)
VR – Interpupillary Distance (IPD) Scale: This allows you to further scale the IPD distance that the VR headset is reporting. Effectively it means you can expand and contract the distance between your eyes.
VR – Show Console: self explanatory
VR – Monitor Mirror Mode: Allows you to set what your normal screen will show while you play. Useful specifically for streamers.
VR – Actor Control Mode: Allows you to define how you want to play the game in VR during the FPS / on-foot sections using the default mouse and keyboard controls. Since we do not support normal VR locomotion yet there are two ways from you can pick:

Pitch-locked (default): The mouse yaw allows you to turn but aiming up and down will not move your head but just your gun pitch angle. You have to manually adjust your head to look along the aim line of your gun. This gives you a stable view (which causes less motion sickness) but a somewhat suboptimal aim experience.
Direct offset mode: The VR camera is directly offset from your normal game camera. Very easy to use but the camera will tilt while leaning or high pitch angles. It is faster to use in terms of normal SC gameplay but less stable and therefore more prone for motion sickness.

VR – Vehicle HUD Projection Distance: Allows you to define at what distance infinity projected vehicle HUD elements are shown (e.g. gunnery PIPs, the Advanced HUD or the aiming crosshair). By default, it is set at 100m at which parallax effects should not be visible anymore.
VR – Visor and Lens Aspect Ratio/Distance/Height/Scale: Allows you to tweak placement of the visor and lens elements.

If you’re unfamiliar with Star Citizen, it’s a PC exclusive, crowdfunded project directed by Chris Roberts of Wing Commander fame. It’s a multiplayer sandbox space simulator that has been in development for over a decade and in alpha for several years. It just received version 4.4 with the third star system, Nyx.

The crowdfunding total for the game just passed $924 million today, and it’s currently sitting at $924,654,813. The game currently has 6,165,492 registered accounts, but we know that not all are paying customers.

Some are alt accounts, while others are simply created to enjoy the “Free Fly” periods in which the game is available for free without requiring a purchase for a limited time.

It’s notable that Star Citizen’s funding tally for 2025 has already passed the previous yearly record, and it’s still November.

A single-player campaign titled Squadron 42 is also in active development with a 2026 release window, starring an exceptional cast of famous actors, including Mark Hamill, Henry Cavill, Gary Oldman, Liam Cunningham, Gillian Anderson, and more.

Since the project has been in development for over a decade, you can see how Squadron 42 has evolved since its first reveal.

Full disclosure: the author of this article has backed Star Citizen’s crowdfunding campaign.
