Yes, of course you can download sdk and check it. FOnline based on AngelScript which is similar to C++. I do not know exactly how is it build but you always ask other peoples who build FOnline - cvet.
Are you going to use 3d models from Mr Karpov had made, Surf Solar? I cannot wait for your release game because it is amazing. Please do this game complete.
Man better if you do this fallout 3 with fonline engine. Better and modern engine and there are a lot of new functions, options. Also I build my Fallout game with that awesome engine.
i am going to make total conversion mod for fonline but now it suck because i complete only 1 location city and 1 small location (i hope do 5 cities and few smaller locations).
i need more critters and scenery for my mod :((
