Graphics and Music just work so great! Physics work as expected. Drone control is good and responsive. Level variations is a good way to keep player interested.
There is only one problem, in levels with multiple guys, when one guy dies level is over. But game don't tell you to restart right away, it lets you play until you delivered rest of them or all of them are dead. Which is bad cause all the effort is for nothing.
Man, this game was fun! (Although I feel like a traitor to mankind)
