Subpen
Taking out the elites was critical to staying alive. If you take too long at the start a guy will discover the boat you came in on.
Mainland
One of the most fun missions in the game. There is a lot to do and not too much that can screw you up when you know what steps to take.
Gunboat
My understanding of the Destroy Infrastructure mission is that you need to shoot a set number of anything, not specific things, so just shoot as much as you can, but don't sweat missing a few. I think everything that blows up counts, so prioritize anything that shoots. This stage took a lot of tries to get right, but I was successful by just holding the fire button.
Post-credits
You don't actually have a mission objective this time, so you never get the staircase scene. A weird, but inconsequential bug to be in the final game.
Note: you keep your ammo and health between mission parts, but they change to a set amount after dying or failing the mission, which is the case for all videos in this series.
