The game is overrun with bots now. They're more subtle than they used to be, they move and shoot. The only way you can really tell is if you watch one closely; they move their turrets mechanically smooth. Sometimes you notice them because two of them (not in a platoon) will both take the exact same route and then sit against a wall, even when that route leads them to some corner no one ever goes. Add it to the list, I guess.
