Doomreal development is officially back to life. Doomreal now depends on Doom Tournament, as it's an add-on for it. Most of the resources are in place right now, just a couple more things left to add in. Flak cannon is still incomplete and weapon development will be resumed soon. There is a main menu now, I hope you like it. Player classes don't have models assigned yet, so they will look weird. Overall this is not yet very playable.
