This topic and all of the chapter topics will list out all collectibles, including trophies in chronological order. Most of the stuff is missable, meaning that there is no free-roam after beating the game. Do not start NG+, and try to keep as much saves as possible - so you can unlock some trophies or save some time if you missed some collectibles along the way.

Immovable Object trophy
A bit later in the chapter, when Hollander escapes during the assault on Junon, a minigame will start where you must stop enemies from reaching the purple outline at the end of a road behind you. You will need to approach an enemy, defeat it, and repeat until you do the same for all 30 enemies. It's really easy. The best way is to say a bit in front of the outline behind you, and just run towards enemies when you see them, and then go back and repeat.

Pre-requisite for Fan Club: Zack Fan Club [Highly missable]
After unlocking the above trophy, do not go in the direction of your objective where Hollander went, instead, turn around and go back in the direction where you came from. You can exit on the side with a lift towards the "Upper Junon – Level 8" area. It's marked yellow on the map. At the top start a conversation with Cissnei, which will later let you join Zack’s fan club in Midgar in Chapter 7. Reaching the Prototype Guard Scorpion boss means you've missed this collectible.

Mail #39: Cissnei – I’ll give you a hint
You will get it after speaking to Cissnei, automatically as you walk towards the Junon airport a bit after the last collectible.
