haha! That reminds me of my own TftD attempt on OXC.. Build my base in/around the Bermuda triangle (seems like a good place to look for sea monsters?) Seen one USO zoom by to the South Atlantic, try to follow but fail. Figure I'll get a terror there, fine. Wait for something in my region.. nothing, get a terror in the pacific somewhere instead (?!) Then I get royally owned because apparently deep sea aliens are impervious to piercing weapons despite running around naked.. Rage quit ensues..
After a bit of research, I learn that
TftD regions are really weird. Especially the South Atlantic going well north of the equator.. I guess the first alien invasion cause a change in the earth's axis of rotation.. But if you look at it, it's entirely possible to build your base at the very top of the South Atlantic region, then you will not see anything as the USOs all go for the middle/bottom of it and only ever get detected on the way, if you're lucky...
What a game..!
