I'm currently trying to get the achievement for beating 1337 mode. However I keep running into an issue where I'll get hacked maybe a few times and then just never again. Anyone know what might be causing this?

going to need a bit more detail, but you dont get hacked if the game is in an enemy state, based on your information that you're playing 1337 mode, it is likely that you've already died and missed lucas's audio queue, therefore you will not be getting hacked when your run is dead even though you're technically still alive.
