P2P Deterministic Lockstep

Demo with an input delay of 6 ticks, artificial latency of 25 ms (50ms ping) and artificial packet loss of 5%. Synchronisation is achieved. Network conditions weren't turbulent enough to cause freezing/locking.

C# Unity DarkRift 2 (messaging library)

Created a stripped-down clone of Divekick, a minimalistic multiplayer fighting game
Implemented the deterministic lockstep networking model
Adopted a peer-to-peer architecture
Utilised both reliable and unreliable channels (TCP/UDP)
Handled serialisation
Simulated latency and packet loss

Bachelor's Thesis: Interfaces in First-Person Shooter Games

Compared four industry-standard types of interfaces for activating voice commands in first-person shooter games: non-nested wheel, nested wheel (shown on the left), non-nested list, and nested list
Developed a 3D first-person shooter (design, programming, art, audio) C# Unity Blender Photoshop Audacity
Deployed a HTTPS server for telemetry Python AWS (EC2)
Conducted online playtesting Amazon Mechanical Turk
Performed a statistical analysis Python (SciPy, Statsmodels, Numpy, Pandas)
In case the reader is interested, I concluded the following. Nested interfaces had a steeper learning curve than their non-nested counterparts. This was expected. However, I didn't find many significant absolute differences in performance (speed, accuracy, effect on gameplay). This may have been a fault of my experimental setup. However, if not, then my results suggest that designers should employ nested interfaces because they offer extra voice commands without notable downsides.
