Drunken Duck Co. · Out now on Steam
Underpacked!
Co-op chaos in space. My first published game, two years in the making.
The game
Underpacked! is a third-person co-op game by the Spanish studio Drunken Duck Co. Cartoon looks, satirical humor and frantic time management: deliver packages across a ship that is falling apart, together with your crew.
It began as a student team project (UCM and Voxel School) that grew into the studio, then into a full production and finally a released game, after about two years of development.
Built in Unreal Engine with FMOD for audio. I also built 5 of its levels, from layout to final pass.
What I did
I worked across six areas, from the first prototype to the final build.
UI
- Mailbox indicator that points to the right mailbox and color
- Level selector with live 3D planets
Technical art & shaders
- Dynamic tube and cable generators
- Object highlights, hologram notification, speed-driven backgrounds
VFX
- Explosions, fire, electricity, smoke
- Package, enemy, thruster and footprint effects
Audio & post-processing
- FMOD integration across every level and system
- Outlines, ship damage and hit feedback
Levels & quality
- 5 levels, from layout to final pass
- QA, playtesting, profiling and optimization
Breakdown
Some of the systems behind the game. Open the details to see how they are built.
Object highlight
Interactable objects glow with illuminated borders and guiding arrows, so the next action reads at a glance.
Material graph
Tube system
Designers build and edit package tubes in real time. Two custom vertex-animated materials show the tube and its direction, with VFX and SFX on every entry and exit.
Blueprint and material
Machine animations
Code-driven tweens give every machine clear feedback on each interaction, plus VFX that communicate its status.
Ammo generator, furnace, turret
VFX & shaders
Explosions, electricity, fire, smoke and package effects, built to stay readable and cheap in a chaotic co-op scene.
More effects
Mailbox indicator
A UI marker travels across the screen toward the mailbox that needs a delivery, in the right color, so eyes stay on the action.
Level selector
Each destination is a live 3D planet. A reusable way to render 3D objects inside the UI lets planets rotate, light up and react to selection.
Hit feedback
A post-process effect fires when the player is hit, so damage reads instantly in the middle of the chaos.
Level production
Five levels for the final game: layout, gameplay setup, lighting, VFX and audio, then iteration after playtests.
