Original Post — Direct link

Now, I know that Diabotical was inspired by Quake, but it won't be a true successor to the original great unless weapon switching becomes faster. Quake 1 weap switching was instantaneous, and it was insanely fun. I wonder what DBT would be like with instant weapon switching.. Maybe we could try it for a week to see how everyone likes it. Just a thought. It makes the gameplay much faster. The original Quake--the one that started it all--would applaud you.

It's possible to create a Custom Lobby with instant weapon switching if you enable that option through a lobby's More Settings button->Instant weapon switch->Enabled (left column, second row).
