Quick update: I am working on two massive projects that aren't ideal for screenshots, hence the radio silence.
One project is netcode. So far I've got a headless server building on Linux, a virtual connection going over UDP, and some nice serialization / bitpacking tools. My code borrows heavily from libyojimbo, which is part of the gafferongames networking article series.
The other project is porting the game to PS4. I finally got the dev kit and SDK set up; it was surprisingly straightforward. So far everything is building except for the one source file which contained all the OpenGL code. I'm slowly translating those GL calls to their PS4 equivalents. The PS4 API is pretty sophisticated and a bit daunting, but the documentation is fine, and overall it's nice to work with so far.
I'll probably continue to write some gameplay code to keep from going insane with low-level graphics and network stuff. I'd like to add more abilities, starting with grenades.
