ask EngiN33R he is master at those scripts.
My opinion: you can already play with a simple zm_ map and zm mod, there's many zombie scripts, you can also do it, but when I looked at your maps I was like:
(no kill pls, no ban pls)
And I just realised, that's imposeble for you.
Game remakes are really big projects and require motivation. Agustindz23 has motivation - I don't. I never played the game, I've barely even heard of it, so I don't really want to remake it in CS2D like I did with TF2 or Space RPG.
Of course, what you want doesn't matter if you're getting paid to do something, but I don't think that's really an option in this case.
@ Agustindz23:
You can't even imagine how hard is it to complete such a long project. You will need a lot of motivation, nerves and time. And you will eventually get bored and just quit the project.
If you really want to see this mod in CS2D, then the best option for you is to make it yourself. Lua isn't that hard, I'd say that it is the easiest programming language.
