Start with the easy chicken! For your own good! Don't be a hero. Everyone knows that's how people get shot in hostage situations. Not that this is a hostage situation. Yet. I suggest you start with the easy chicken. Just saying.
It's such a shame. Unbalanced missions, constant 1-hit kills by the enemies, limited options on order and naming, no damage numbers, no ability to stay prone in position, no good old "aim" feature. It just feels like a dumb luck rush now. And I'm very unlucky.
