However, with six just behind a gate, all six units will suddenly start streaming through the bottleneck the minute some poor levy touches a sarissa. And they do so at ridiculous speeds, actually knocking the enemy into the air. I've no clue as to why.
Yes, but when you stack another pike phalanx on top of the original one, it prevents anything from getting past, provided you hit "Backspace" every few seconds. That is what I did in the bridge battle.
