I haven't posted an update in a while, but that's because I've been hard at work adding online multiplayer to Aground Zero. Multiplayer is always a large amount of work, and there's not much to share during it's development, but it's halfway complete and I hope to release online multiplayer by the end of June (with a beta available before that). Earlier today, I streamed the first test of online multiplayer, with a fellow developer, which you can watch below:
I hope you're looking forward to online multiplayer, and I'm starting to accumulate new 3D models for the next section of the game I will start on after it is complete. There probably won't be another update until the multiplayer beta test, but rest assured progress is being made!
