I used Hammer a little, but I couldn't be fucked to learn the more advanced features. I can make doors really well though.

It's hard work. I wanted to assemble a team via moddb.com, but thought it would be better to try
and assemble a closer team of people with smarter minds that didn't just want to make "zombie apocalypse"
games!

Good luck with that.  I mean it...

You know what's the hardest bit? Compling it into an actual mod. There's no tutorials anywhere on that.
I can make maps and skins and I know a bit of coding, but I don't actulaly know how to make "New Game"
put you on that map!

There are a ton of tutorials, dude. Look harder.

I've just recently started fiddling with Hammer, and I can create blocks and drop props onto a map like nobody's business.  As for making an actual functioning map, though...I'm still working on that.
