I'll also see if I can get my 'Dead Stop' campaign + another unfinished level, both of which led to the current campaign of 'Dread Alert' that I am working on.
'Dead Stop' started with HL2 props, but then I can't put them into Left 4 Dead, so I quit that map, and made another one with the hacked SDK. Lost inspiration on the second map, and the pictures
.
This other campaign I was designing never saw daylight because I got bored + the fact that I can't have a crescendo on a moving object.
Thankfully, I put some elements from Dead Stop and the unfinished level into Dread Alert.
