I've been receiving some questions that have been commonly asked of me lately so I think it's time to address them en masse.
Ledge grabbing status?
Broke as fuck. Slowly working on it. Need to enslave Michaelis once more.
Where are the rest of the Multiplayer weapons?
On hold for the moment. I'm waiting on Franco Tieppo to continue negotiations. But they will come, probably by his hand directly instead of through D4T.
So D4T converted its powerups to Doom 2016's...
And D4D will not. It will maintain the route it's going because I honestly like the Quake powerup effects much more than Doom 2016's. I'm not going to budge on this, so you'll have to find someone to make an addon that replaces them.
Plans to bring in a menu like Doom 2016's with the upgrades and all?
Hopefully. But that's going to be extraordinarily difficult. First step, let's see how hard it is to bring back D4D v1's menu...
Multiplayer?
When GZDoom can support it. Definitely planned.
Why wait on GZDoom? Can't it be done on Zandronum?
Not even remotely. Zandronum devs are getting another thing coming to them when it comes to ZScript, and chances are likely they will have to restart on top of GZDoom once again. Besides, you have D4T if you want it NOW NOW NOW so don't go barking up the wrong tree JUST yet.

Can the upgrade menu become a portable viewer in Pickup upgrade mode?
Yes, it will be by the time the next update comes around.
Submodules?
Maybe.
Hey, you remember that reeeeaaaaally old Hell on Earth Starter Pack you promised?
I never promised. I stopped working on it when ZScript became a thing, because it means I can grant you all a bunch of even better shinies.
Fast weapon switching after firing--
--is coming. I've decided to unshackle all that shit, you're going to need it for some of the nasty surprises I've planned along with it.
And your addons?
D4D called shotgun. They're in the back seat, but still being given attention -- plenty of it.
How about some new monsters?
Want to volunteer? D4D is open source.
