The second step to get the ace of spades requires you to kill 5 invaders in gambit, which is a lot harder than it sounds. There’s many reasons why; they spawn with an overshield which makes it almost impossible in a 1v1 situation. They also know where you are at all times which doesn’t help either. All your teammates shoot at them too so you most likely will not get the kill and they are most leaky using 1 shot or long range weapons so good luck with that. They also seem to spawn in when there’s a lot of enemies so you will also have a high chance of dying to ads so yeah all in all they really need to change the step to make it easier since I am not lucky like a lot of people out there
