Due either to biology, cybernetics of otherwise, you have the ability to see at a much wider angle than others. While most species are stuck with about 160 degrees field of vision, you can see further. This ability can be taken multiple times for additional viewing angle.
+1: 180 degrees (you can see directly beside you)
+2: 200 degrees (you can see slightly behind you)
+3: 280 degrees (you can see everything but in a 45 degree angle behind you)
+4: 360 degrees (you see everything around you)
