A few observations...
First, when I read "Dead City", I thought you were referring to the forum.
I think it's a shame that people make sites with multiple fake download links. It took 3 tries to find the real download link for your game and not one that was either an ad or a download for a program they want you to install that downloads for you.
And , I found no malicious code in the download.
Now, on to the game.
It's a good start. You have a jump on many who never put anything together. At the moment, it looks like a lot of randomly placed, random stuff. Kind of like playing that game... "Which of these things doesn't belong?". In time you'll learn to add realism by using items that fit well together (what you might find in a real environment) and placing things in a more realistic way. For instance...
Fires need fuel. Put something that burns in your fires.
Fences normally fence things in.
Don't mix a wood shack with a sci-fi wall and an overhead garage door. I want to shoot your interior decorator.
Try not to use the same item too many times, like the bus.
Give your AI some cover or purpose, not standing in the open.
It takes time to learn and develop your own style. You'll want to start creating your own content at some point to make everything come together the way you want it.
It would help to give the player some kind of purpose or mission in the game. I was just running around shooting scores of AI. I don't know why they were there or what they were doing. I don't know what I was doing. Don't get me wrong, a random, meaningless killing spree after a hard day of work is great, but to do it right I'd really like a tactical shotgun.
Keep working at it.
Brian.
