Overload is one of the best retro FPS revivals out there. Simply put, it’s Descent 4 in all but name, developed by the original crew, complete with a soundtrack from the combined composers of the original three games. The only real complaint I had about it in my mini-review of it here was that it was a little on the short side, despite an excellent New Game+ mode. That became less of a problem this week, as developers Revival Productions released the level editor for it, along with a basic tutorial video within.
