Metal Gear Solid V: The Phantom Pain

- Enemies don't shoot down balloons unless they see it and have time to react. If they catch the tail end they'll radio in an alert but unless someone is 10m away and looking right at you they probably won't shoot the balloon. You can totally fulton the world and everything is reset when you replay a mission.

- Night vision is really only functional useful at night. Maybe they can be upgraded to Ground Zeroes style where they're basically permanent Predator-vision but at the start they're not a crutch you can rely on.

- Named areas on the map usually have an anti-air radar that looks like a trailer with a giant dish on top. They're not the same as the comm units which are platforms with a little radar on top. Destroying them lets your helicopter land closer which is useful during side ops.

- You change your helicopter on the customize screen of motherbase. It took me a while to figure this out as I kept looking in the vehicle section of the loadout.

- Pressing triangle while prone plays dead but it somehow reduces your profile to nothing. At night, enemies will practically step over you.

- Holding L1 brings up the commands screen where you can "knock" anywhere. It doesn't require you to be pressed up against a wall so split up guards with magazines and knock to draw them out one by one.

- Flare grenade supply is the best item. You can instantly get your current loadout to top off on suppressors, ammo, and fultons without having to fumble through the menu to call in a supply drop.

- If you overhear people talking about a super fast naked woman at a specific location don't follow up on it. It's story related and comes later. D-Dog on the other hand is easily missed,

he's mission 5, take the default drop point. A little up the hill he'll come barking at you.

- If you're strapped for cash then sell off weapon emplacements and unnecessary plants. They're worth quite a bit.
