I’ve heard that’s it’s extremely difficult to make invasion maps, so I’m wondering if somebody could provide a 'link or some tips on how to make a good inv. map, and possibly tell me the major differences in the inv. map making to normal map making.
I personally thank you , kind sir or mam, for providing this supremely helpful link.Its true that I could have looked up what I was asking for on google or something, I was going offline for some hours, and wouldn’t be abe to fully look my question up.Again, you have my thanks.
Okay, it seems like my question has been answered;so nobody post on this thread unless they have a better link to an invasion map-making explanation.
Also, I thank the moderator who moved this thread, I was clueless as to where to put it
