Thank you guys for responding in such a clear and helpful manner. I'm new to Xcom modding as well. I would love to see this or a similar thread stickied since gives us newcomers a quick rundown of things. Now to my question. Are there any alternate ways of modding other than using modpatcher.exe? I was thinking about using the Resource Hacker ( http://xcom.nexusmods.com/mods/55 ), it seems more straightforward to me. Are there any pros and cons between using the resource hacker and the method involving modpatcher?
