Players looking for their next frantic co-op addiction will find that testing out the free GRAVHOUNDS demo offers a robust preview of the game’s core survival loops, quirky humor, and tactical depth.

Whether you are coordinating titanium pipelines under heavy fire or reviving a downed squadmate wearing the dreaded "cone of shame," success in this game demands both strategic planning and quick reflexes. In this comprehensive guide, we break down everything you need to know about navigating the demo, mastering planetary logistics, choosing the best turret builds, and safely evacuating your crew with full resource hauls.

What Is GRAVHOUNDS? Core Gameplay Loop and Mechanics

At its heart, the game tasks a squad of canine operatives with touching down on hostile alien biospheres to harvest high-value mineral deposits, establish automated supply lines, and defend central collection nodes against aggressive fauna. Early community gameplay reports highlight how smoothly the title merges factory-automation elements—reminiscent of titles like Satisfactory—with frantic extraction shooter mechanics.

Every expedition follows an escalating rhythm. Once your drop pod slams into the planetary crust, your team must scout nearby points of interest (POIs), locate primary resource nodes such as titanium veins, and connect raw resources back to the central base collector.

[Drop Pod Insertion] ➔ [Scout POIs & Veins] ➔ [Automate Logistics Line] ➔ [Defend Refinery Waves] ➔ [Evacuation Shuttle]

Logistics are not purely menu-driven; you physically lay down conveyor belts, construct refineries, and build fabricators right in the middle of potential enemy pathing lanes.

Mission Structure Overview

The demo introduces players to procedural planetary maps featuring variable environmental hazards, steep elevation shifts, and localized alien nests. The table below illustrates the primary phases you will encounter during a standard planetary run:

Mission Phase	Primary Squad Objective	Key Risks & Threats	Critical Gear / Tools
1. Insertion & Scouting	Drop onto landing zone; tag titanium deposits and nearby POIs.	Fall damage from cliffs; roaming bug patrols.	Dowsing rod, basic blasters, movement boosters.
2. Logistics Setup	Place conveyors, pipelines, and the central fabricator.	Split squad focus; unattended nodes under siege.	Conveyor tracks, pipeline connectors, resource splitters.
3. Node Defense	Protect mining drills and the base collector during waves.	Swarms of spiders, spitting bugs, and heavy bio-tanks.	Automated turrets, laser barriers, repair packs.
4. Evacuation Prep	Finalize collection, complete launch sequences, and reach evac.	Heavy bosses (Giant Lizards, Armored Frogs), overwhelmed lines.	Heavy artillery (Rocket Turrets), squad revives, frisbee teleports.

Community playthroughs emphasize that team coordination is mandatory. If all players wander off exploring ruins, the home base collector will quickly collapse under sudden enemy waves. Conversely, if no one scouts, you miss out on advanced blueprints and defensive tech that make later waves manageable.

Defensive Arsenal: Turrets, Barriers, and Upgrade Paths

Defense in the GRAVHOUNDS demo relies heavily on automated static emplacements to channel and eliminate alien swarms. As raw materials flow along your conveyor belts into the fabricator, your squad earns building points and credits to manufacture defensive structures.

Turret Types and Synergy

Placing defenses haphazardly will quickly exhaust your power grids and titanium stockpiles. The key to surviving higher threat tiers is pairing single-target high-damage emplacements with wide-area crowd control systems.

Defensive Structure	Damage Profile	Resource Cost	Strengths	Weaknesses
Automated Turret	Kinetic / Rapid-Fire	Low Titanium	Cheap to mass-produce; reliable against light aerial bugs.	Weak against heavily armored targets; low durability.
Laser Turret	Continuous Thermal Beam	Medium Titanium	Melts single targets; pinpoint accuracy across medium range.	Struggles against dense, scattered swarms.
Rocket Turret	Explosive / Splash AoE	High Titanium	Devastating burst damage; eliminates clustered spider waves.	High ammunition cost; slow projectile flight speed.
Electro Coil	Chaining Electrical Shock	Premium / Tech Drop	Stuns and arcs between multiple tightly packed monsters.	Requires dedicated research blueprints; shorter range.
Laser Fence Post	Environmental Barrier	Low-Medium Credits	Channels alien pathing; fries weak swarming enemies on contact.	Can be bypassed by leaping or flying enemies.

Player experience demonstrates that laying down laser fence posts to create artificial choke points allows your rocket turrets to maximize their splash damage. Placing your fabricator within proximity to both the collector and primary defensive walls ensures that repair and replacement routines do not leave critical chokepoints undefended.

Exploration, Blueprints, and Side Objectives

While mining titanium keeps your defensive perimeter funded, exploring the wider map in the GRAVHOUNDS demo is essential for acquiring long-term advantages. The planetary surface is littered with ancient bunker doors, environmental puzzles, and high-value side missions that reward game-changing blueprints.

Environmental Mini-Games and Scanners

Scouting canines will frequently encounter sealed storage crates and bunker hatches locked behind interactive pressure pad mini-games. Players must coordinate stepping onto synchronized plates or aligning power dials (matching rotating colored nodes from yellow to green) to unlock secret compartments.

Using the scanner tool or dowsing rod allows scouts to locate hidden supply caches buried beneath tundra or desert terrain. When you discover an advanced turret blueprint—such as the continuous beam upgrade—you don't have to carry it all the way back across the map on foot. Instead, player experience shows you can toss recovered items directly onto your outbound conveyor belts, automatically ferrying valuable tech straight back to your base fabricator.

Special Side Escorts: The Coffee Cat

Beyond tech retrieval, maps often generate quirky secondary tasks. In one notable objective featured during community gameplay, players must rescue and escort an alien feline dubbed the "Copycat" (or "Coffee Cat") back to the collector terminal.

Side Mission / Event	Required Squad Action	Strategic Benefit	Risk Factor
Pressure Pad Vaults	Coordinate 1–2 players on timing pads.	Unlocks rare weapon variants and heavy turret designs.	Leaves base defense short-handed during incoming waves.
Pipeline Alignment	Manually calibrate directional pressure wheels.	Restores broken refining lines to accelerate extraction speed.	High vulnerability while trapped in the mini-game interface.
Mascot Escort (Coffee Cat)	Protect a non-combatant VIP moving across the map.	Massive credit bonuses and base ship amenities upon return.	Moves slowly; draws ambient enemy agro from nearby nests.
Signal Beacon Tracking	Follow directional radio pulses to crashed pods.	Grants instant supply pods and high-tier defensive treats.	Often stationed near elite mini-boss spawns.

Completing these objectives before triggering the final launch sequence dramatically increases your end-of-mission credit yield, letting you unlock vital base-ship upgrades much faster.

Squad Survival: Downed Mechanics and Canine Abilities

Combat in the game is fast-paced, third-person run-and-gun action punctuated by canine humor and unique mechanics. Every dog class features mobility gadgets, bark actions, and quirky survival states when their health drops to zero.

The Downed Loop: Plushies and Cones of Shame

Unlike traditional shooters where dying means staring at a black screen, the GRAVHOUNDS demo leans into comedic resilience:

Plushie State: When your canine health bar is depleted, your character turns into a small, marketable squeaky plushie. While in this state, you can roll around the battlefield to escape stomp attacks, though your combat abilities are disabled.
Squad Revives: Teammates can physically pick up your plushie form and throw you toward safety, or carry you to active healing bubbles generated near the collector.
The Cone of Shame: Once revived from a critical state, your hound wears a glowing "cone of shame." While restricted in vision or weapon spread temporarily, you recover quickly and can rejoin the firing line.

[Full Health] ➔ [Depleted HP: Squeaky Plushie Form] ➔ [Teammate Toss / Revive] ➔ [Temporary Cone of Shame Recovery]

Mobility is equally fluid. Canines can utilize throwable frisbee beacons to instantly teleport out of high-density swarms or jump into defensive boats and mine-cart rails to escape closing jaws.

Weapon Loadouts, Star Ratings, and Permanent Ship Progression

Surviving the final planetary launch rewards your squad with credits, construction performance metrics, and star ratings based on overall mission contribution. Returning to your orbital hub opens up deep progression trees for both canine stats and offensive weaponry.

Research Lab Upgrades

The hub ship features modular research stations where titanium and credits convert into permanent stat enhancements. If you want to tackle higher-tier difficulty planets, investing in baseline survivability and logistical efficiency is paramount.

Upgrade Category	Key Node Enhancements	In-Game Performance Impact
Mobility & Boosters	Jump-pack thrust, sprint duration, rail-sliding speed.	Critical for outrunning fast-moving subterranean spider swarms.
Mining Efficiency	Drill speed, extraction yield per vein, conveyor transfer rate.	Cuts extraction time down significantly; reduces total defensive waves.
Weapons Handling	Reload speed, magazine reserves, stability mods.	Allows solo players to hold off waves without relying solely on turrets.
Defensive Architecture	Turret health, barrier power grids, automated repair speed.	Keeps base operational even when elite bosses breach outer walls.

Available Primary Weapons in the Demo

When spending your earned credits between deployments, players can customize their active weapon slots. Early demo builds spotlight several distinct firearms:

Standard Blaster: Balanced automatic rifle effective at medium ranges.
Scatter Shotgun: High-impact, close-range spread weapon designed to shred swarming bugs that bypass your turret grid.
Long Bore Rifle: A high-precision sniper rifle built specifically for popping elite weak spots (such as flying spitters and armored heads) from atop cliff edges.
Rocket Grenade Launcher: Heavy ordnance designed for direct boss health-bar chunking.

Threat Analysis: Best Countermeasures for Elite Swarms

Alien fauna on these mining colonies comes in varied shapes and sizes, escalating from annoying pests to colossal bio-titans. The table below outlines the primary enemy threats encountered across early mission tiers and the recommended tactics to neutralize them:

Threat Name	Enemy Classification	Primary Attack Pattern	Optimal Counter-Strategy
Cave Spiders	Fast Swarmer	Surrounds squadmates in melee clusters; leaps over barricades.	Rocket Turrets, Scatter Shotguns, and Laser Fence Posts.
Acid Spitters	Ranged Aerial / Ground	Hurls corrosive projectiles from afar; disables turret targeting.	Long Bore sniper rifles; pinpoint Laser Turrets; bark disorients.
Bile Lizards	Armored Bruiser	Charges directly at pipelines; spits swarms of flying parasite drones.	Concentrate continuous beam lasers; kite around elevated terrain.
Giant Leaping Frogs	Elite Siege Unit	High vertical leap landing directly on base collectors; knocks players away.	Stun-lock with Electro Coils; dodge ground slams using jump boosters.
Armored Shrimps	Heavy Behemoth	Frontal armor plate that deflects light kinetic fire; sweeps players off cliffs.	Flank exposed rear weak spots; drop explosive reward pods directly overhead.

Player experience notes that physical environmental physics can also be turned against enemies. Throwing supply pods directly onto advancing elite units deals massive blunt crushing damage, often killing medium-tier enemies instantly.
