I didn't see a thread for this, so I decided to create one. The new EDF is out today (actually started showing up Monday). Major new features over 2017 include online multiplayer and multiple playable classes. I've only played a few missions so far, but they've definitely polished up quite a few things since the last one. Unfortunately, that means the game has also lost a bit of its charm (no more, "Damn you mothership! Did we wake you up?").
