What GRAVHOUNDS Brings to the Co-Op Extraction Formula
Developed by Octopus Panic—a Seattle-based, seven-person independent studio founded by industry veterans with past credits across franchises like Halo, Battlefield, Star Wars, Full Spectrum Warrior, and The Saboteur—GRAVHOUNDS blends physics-driven base building, third-person shooting, and high-stakes planetary extraction.
According to studio co-founder Josh Holmes writing on Xbox Wire, the premise casts players as a squad of bio-engineered canine industrial workers stranded on the far side of the galaxy. Under the watchful eye of a shipboard AI supervisor named COSMO, your pack still has quotas to hit. Each shift drops one to four players onto hostile alien worlds to salvage technology, harvest high-value resources, and establish industrial infrastructure while fending off an escalating alien swarm.
Rather than treating base construction and combat as separate phases, GRAVHOUNDS merges them into a single, frantic loop:
- Gravity Manipulation (The Grav Beam): Every worker carries an industrial Grav Beam capable of grabbing resources, hauling Build Kits, flinging volatile materials across the battlefield, or yanking smaller alien creatures out of the fight to hurl them as improvised projectiles. As the official Steam store description wryly warns, transporting volatile materials with the beam can result in the "unforeseen loss of Gravhounds."
- Pipeline Logistics and Defense: Pipelines act as the central nervous system of every planetary operation. Extending pipelines across treacherous terrain carries power to remote generators, fabricators, and defensive turrets while keeping your extraction route alive. Pushing pipelines farther reaches richer resource deposits, but also leaves more exposed infrastructure to defend.
- High-Speed Propulsion: Players wear industrial propulsion rigs that let them jump, hover, and boost in any direction under heavy fire. Hopping directly onto an active pipeline supercharges the rig, allowing players to grind along the pipe network with unlimited boost to rescue an overwhelmed teammate or shore up a collapsing perimeter.
- Mid-Shift Roguelite Escalation: Contributing to the mission earns Reward Pods containing randomized weapons and upgrades. Players can stack bonuses and reshape their loadouts mid-shift as the alien swarm grows progressively deadlier the longer the crew delays extraction.
Section Summary: GRAVHOUNDS combines cooperative extraction shooter tension with real-time pipeline logistics and physics manipulation, forcing teams to balance greed against an endlessly scaling alien threat.
Demo Content, Platform Availability, and Schedule Details
For players eager to test their industrial mettle before November, it pays to look at how the demo rollout is structured across platforms.
On Windows PC, the free GRAVHOUNDS Demo launched on Steam on October 12, 2026, timed ahead of Steam Next Fest, with press announcements from Games Press and Capsule Computers noting an initial PC playtest demo window running through October 18. Alongside the Steam release, an official GRAVHOUNDS Demo store page is also listed on the Microsoft Xbox Store, and Netto's Game Room reported the demo's availability across Xbox Series X|S and PC on October 16 alongside the game's showcase trailer.
According to Octopus Panic's press announcements reported by Games Press and Gaming Furever, the demo slice includes:
- Two Solar Systems and Seven Planets: Players can drop into seven distinct planetary environments with varying hazards and resource layouts.
- Four Playable Gravhounds: Squads can choose between four bio-engineered canine workers—Selene, Zane, Dozer, and Finn—each bringing distinct strengths to solo or four-player online co-op expeditions.
- Mod Deck Builder: Capsule Computers notes that the October demo build also introduces a new Mod Deck Builder for customizing worker capabilities.
There is one important practical limitation to keep in mind before grinding for hours: the studio has noted in its Steam community announcements that demo progression does not carry over into the November release. Instead, the pre-launch build serves as a hands-on preview and a live playtesting environment for gathering community balance and technical feedback.
Section Summary: The playable demo features four characters (Selene, Zane, Dozer, and Finn) and seven planets across two solar systems, though progress made during the demo will not transfer to the full release.
Windows 10 and Windows 11 PC System Requirements
Because GRAVHOUNDS relies heavily on real-time physics interactions, object flinging, and expanding enemy swarms, Windows PC builders will naturally wonder how demanding the game is on local hardware. Fortunately, according to the official GRAVHOUNDS Demo listing on Steam, the hardware footprint is remarkably approachable for mid-range gaming rigs and modern handhelds alike.
| Specification | Minimum PC Requirements (Steam) | Recommended PC Requirements (Steam) |
|---|---|---|
| Operating System | Windows 10 (64-bit required) | Windows 11 (64-bit required) |
| Processor (CPU) | Intel Core i5-7600K or AMD Ryzen 5 1600 | Intel Core i5-10600KF or AMD Ryzen 5 3600X |
| Memory (RAM) | 8 GB RAM | 16 GB RAM |
| Graphics (GPU) | NVIDIA GeForce GTX 1660 or AMD Radeon RX 590 | NVIDIA GeForce RTX 2060 or AMD Radeon RX 5600X |
| DirectX API | DirectX Version 12 | DirectX Version 12 |
| Network | Broadband Internet connection | Broadband Internet connection |
| Storage | 6 GB available space | 6 GB available space |
A few technical details stand out on the Steam store page for Windows users:
- Compact Storage Footprint: Requiring just 6 GB of available drive space, the demo is an easy install on solid-state drives without forcing you to clear out massive triple-A partitions.
- DirectX 12 Baseline: Both minimum and recommended tiers require DirectX 12 and a 64-bit Windows environment, with Windows 11 specifically designated for the recommended tier.
- Multiplayer and Language Support: The Steam listing confirms single-player and online co-op functionality, with full English audio, interface, and subtitles, plus localized interface and subtitle support for French, German, Spanish (Spain and Latin America), and Brazilian Portuguese. The store page does not list local split-screen co-op or specify cross-play details, so squads should plan around online matchmaking with their crew.
Section Summary: GRAVHOUNDS targets mainstream DirectX 12 hardware on Windows 10 and Windows 11, asking for only a GTX 1660 / RX 590 at minimum, an RTX 2060 / RX 5600X as recommended, and a modest 6 GB of storage space.
Road to November 2: Xbox Game Preview and Day-One Game Pass
While the October demo gives players an immediate taste of planetary salvaging, the bigger milestone for the Microsoft ecosystem arrives on November 2, 2026. As confirmed on Xbox Wire, GRAVHOUNDS will officially launch into Xbox Game Preview on Xbox Series X|S and Xbox on PC, as well as Early Access on Steam.
Even better for subscribers, Microsoft and Octopus Panic confirmed that the game will be available day one with Xbox Game Pass. For a cooperative PvE game built around systemic chaos—where half the fun is accidentally launching a volatile canister toward your best friend while trying to wire up a turret—day-one Game Pass inclusion removes the barrier to entry for assembling a full four-player pack across console and Windows PC.
As Josh Holmes explained on Xbox Wire, launching into Game Preview is a deliberate choice for a seven-person studio building a systemic co-op title, allowing the developers to refine balance, upgrade combinations, and co-op interactions alongside active players. Whether you jump into the demo now or wait for the November 2 Game Pass drop, just remember the golden rule of interstellar canine contracting: keep the pipelines powered, watch where you aim the Grav Beam, and extract before the swarm collects your pelts.
