I've never used any game engines and I don't know a whole lot about programming. But, I am working on creating a huge game and before I buy this engine I would like to know a few things.
1.Can I create custom weapons?
2.What gameplay features would I be able to add?
3.Would it be possible to create an entire city type environment where you could enter almost every single building?
4.Are there any pre-made zombie models available to download?
Responses are appreciated.
