My mom is against those kinds of games
Although if i put the gun away i can fake them out and pretend im invisible
My grandmother watches me play in the corner of the room and comments saying "That's bad, you shouldn't shoot people."
Once I used a tank to run over some players, and then use its main cannon to finish them off. You can hear her going "Oooh my Gaaaud."
Too bad it was in the Ukraine when I visited.
