Ben Schiffler is a Game Designer, Layout Artist, Computer Scientist, and Storyteller based out of the Seattle area. This design portfolio documents several projects he has created over the past few years.


KaijuKart VR is an asymmetrical multiplayer VR game project built by me as a solo project for the University of Washington's 2016 Design Show. Built in Unity for the HTC Vive, it pits four players racing hoverkarts against a single player in VR who acts as a giant trying to squash them with rocks.


The Goal

I came into this 10-week project with a specific and flexible goal. I wanted to create a working, playable Virtual Reality game. I wanted to adapt to the unique design space of VR, while teaching myself multiple game development tools and producing a finished game that friends could play in VR at the final design show.


The quarter before I began this project, I took an independent study to try and understand the current VR Design space.Using a Oculus DK2 donated by Pluto VR, a beefy rig from the computer science department, and a lot of Googling, here’s what I found:


VR is an exciting and innovation-friendly field. This is amazing as it allows for many potential new design solutions. Yet it also has a frustratingly high cost and tech barrier to entry, on top of being very difficult to explain and advertise.


VR requires a lot of space, money, and technical know-how. So, most VR experiences are held in a group environment where resources can be shared. While this is a great opportunity for multiplayer, sadly only one person can use a VR headset at a time.

Games have a history of asymmetrical design, connecting players across platforms and genres. This design philosophy has not yet been heavily pushed outside of the innately asymmetric PSVR, despite it's possibilities with such a hardware-reliant platform.

The Design

I aimed to exploit this open gap of asymmetric multiplayer in VR. My initial design pit players outside of VR as race car drivers. A last player stood with a VR headset, acting as a Godzilla figure knocking them about. From that pitch, I contacted some friends to help me mock up what this might look like.



It immediately became clear that the Giant and the Racers needed distinct design aesthetics to separate their spaces. With the racers I gravitated to splashy, colorful, punk-esque colors to make them immediately identifiable by the VR giant; while the giant took on more peaceful, foreboding, and ancient tones. Sample mood boards are below, and see the full board on Pinterest here.



I couldn't just jump into the final build, as I still knew little about VR development, multiplayer networking, racing simulation, and physics-based gameplay. So to teach myself over five weeks, I created 11 additional games to teach myself these tools, six of which are below.

The first pass

Using the core of the "Networked VR Car Driver" game above, I built a first pass of this asymmetric racing game I now called "KaijuKart", in reference to Japanese Kaiju movies and good ol' fashioned MarioKart.


Character Development

Designs and development of the "Racer" character, who rides in the cart driven by the Non-VR players. 



No design happens in a vacuum, game design least of all. During development, I was required to design creative solutions to deal with tricky technological problems. 


I knew that the more hands that tried out the game, the better it would end up being. I could only fit in one day of playtests due to time constraints, but I aimed to get the best results. Over 15 different people tested the game and provided interview feedback with 2-5 players playing at a time.

Playtest Takeaways

A great deal of notes, good ideas, experiments, and fresh bugs came out of this playtest (heavily proving it's worth). Among the notes were many important pieces of wisdom some of which are included below, with a full writeup of my notes available here on Google Docs.

  • Most fun was had just playing around with VR & kart mechanics
  • Kart physics needed an overhaul
  • VR Monster needed a presence
  • Terrain too bumpy, scale too small
  • Players kept colliding with objects, better boundary projection wanted
  • Enjoyed the VR physics handling
  • Formal game mechanics were not mentioned as much as I'd expect


I had two weeks to polish the game after the playtest, I chose my priorities from the feedback. Racing mechanics were completely rebuilt, the environment redone, and physics colliders were fully reworked. 

Formal game mechanics (win conditions, score, etc) were always on my radar, but testing showed people were far more interested in having a visible model of the monster, so my final push focused on that instead (to great success)!


My final presentation of KaijuKart VR was at the UW Capstone Design Show at the Jacob Lawrence gallery. The show webpage which I helped work on can be found at

My project was in Gallery C,  a roughly 10x10 space that presented several design challenges for setting up a 5-player multiplayer game. Chief among those was acquiring four laptops (generously lent by the UW's STF Program) and a VR-Capable PC (generously lent by local startup Pluto VR).

My designed layout optimize traffic flow for five players, observers, and myself in the space. I used a wall-mounted monitor display to show to viewers a pdf process presentation, as well as the VR Monster's view when there was an active player. A wall-mounted poster documented the development process.


Thanks so much for reading and checking out my project! If you'd like to check out the project in more detail, downloads are available below. This project was a dream for me to get to make, so thank you so much to everyone involved!
