W to over towards mouse pointer, Space to shoot (bar above self is for reload) Kill as many enemies as you can. Multiplayer so you can see a high score and a list of players and their scores. No usernames are in the player Kills list; just numbers (UID) If you are playing with friends you can see the number you display at the top of the screen. I don't recommend checking the cloud history for high score setters because it is a multiplayer game.
