Mission 30 doesn't seem very great. It's essentially death if anyone spots you. At least the checkpoints seem generous.
Or you can just
Sneak through the first gate, jump in the tank parked right inside and drive all the way up to the stairs shooting the walker gears in about 2mins and get an S rank
I need some help with Episode 29. Having a lot of trouble and I feel like I'm missing something.
I know to hit R2 to counter the Skulls' knife attack but what should I do after that. Nothing does much damage, even rockets, and I don't have enough ammo to deal with more than two. It seems like I'm missing the follow up to the counter.
As you exit the cutscene,
run to your right and climb the ladder..they can't climb ladders and will rarely teleport up there, can take your time and just dodge rocks.
