All this talk of doom has made me nostalgic of late so I have done a little digging an guess what I found Alpha an Beta versions of doom one an two available to download ID has given permission to have them out there for historical reasons I am downloading them an sticking them in a VM should be fun.
Doom Alphas and Betas Weird that the rifle didn't make it into the final game oh an I find it more impressive that the first demo was released at the two month mark.
