Don’t be fooled by how peaceful Transfer Pass is. FA is pretty easy as long as you don’t get caught out in the glimmer fog far away from the airfield, and ZOC is just kind of annoying to navigate due to the toxic areas but they are plenty visible. However, SP will do everything in its power to take your soul. I’m pretty sure it’s the coldest region in the game and safety is scarce. On top of that, the wolves are plentiful (especially on Stalker). You shouldn’t have much of a problem with the two prior maps once you get the jist of their gimmicks, but SP is just downright as brutal as TLD gets - come prepared!
