Aye the start is so hard to getting it right that I don't seem to last beyond the first infection but it is fun still trying to get there I can't seem to do any waypoints though with shift click or make the patrols more than from point A to B.
The Fall Part 2, the second part to one of my favourite games of the last few years, came out yesterday. I can't recommend this game enough and if you buy Part 2 now, they throw in Part 1 for free.
