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.

- If a mission tells you to assassinate someone, no matter how explicitly, don't. They generally have obscenely good stats in at least one field, so Fulton them instead.

- Once you press up against cover, you can let go of the control stick and don't have to keep pressing against the wall

- Upgrade the Cargo Fulton to max before doing anything that involves eliminating vehicles, especially the side-jobs that aren't repeatable. You can steal them instead for yourself, or for profit. Yes, even a Tank.

- Anytime you get a sidequest or even a story mission that says "Eliminate X", tranq and Fulton them instead. They generally have insanely good stats (At least one A+/A++). Their surrounding guard squad usually each have at least a B in something as well.

- D-Dog is your best Buddy. He'll point out every enemy in visual range, and once you give him a Sneaking Suit of his own DD can make silent assassinations with a knife. DD is a Good Dog .

- You may notice that your guns make mention of accessory slots but can't do anything with them, along with mention of specific stocks/scopes/etc. You can fully customize your weapons by completing the Legendary Gunsmith sidequests.

- Get a Support Platform first for Mother Base. It'll tick over periodically to give you free resources.

- Learn how to use the tranquilizer's delayed effect if you want to take out guys in a group without them all shitting themselves because one dude fell asleep in front of them. A round of chest shots to all involved will quietly send them all to slumberland near-simultaneously with a bit of patience.

- Vehicles cost nothing to deploy, so don't fret about having to bring out D-Horse just to travel around. Fulton yourself a Jeep and you're set.

- Once you get to the point that you can make multiples of struts at Motherbase it might be for the best to upgrade the Command Center first as it increases the personnel capacity for all the struts.

- Guards are fairly adaptable to your bullshit although I think it takes a bit for them to actually adapt, like maybe if you leave the area or complete a side-op or mission. So those tactics that they use which are indicated on the map screen are a result of your actions. Use headshots a lot and they'll get helmets, attack at night a lot and they'll get flashlights, and other things like bullet proof vests, shotguns, machine guns, security cameras (I think, I haven't seen one yet, but that's the icon for stealth deterrence), etc. They'll also start investigating things in pairs if you like to split them up.

- So you can either try changing up your tactics OR once you get a Combat division you can eventually send them on OPs to destroy the enemy's supplies (helmets, vests, guns, etc).

- If you're gonna want to capture Quiet you're probably gonna want to have a tranquilizer sniper rifle, so prioritizing the development of one once you hear guards mentioning some mystery woman might be in your best interests.

- To that end there's an option to re-auto-assign everyone in Motherbase, so if you move a bunch of people around to departments that aren't their specialty to up the levels for development projects, it's easily undone. Although you'll still have to move the direct contract people you've locked down, or at the very least Miller and Ocelot who are direct contracts by default I think.

- Once you get the Fulton device, pull everyone out that you can (yes, even the E-rank trash soldiers) until you fill up every slot in every team. That way, instead of the game putting your new A-rank R&D guy in your combat unit because there's no room on the R&D team, it'll automatically put them in the right place and knock the lowest skilled guy on that team into the waiting room.

- You can't complete all the objectives on some missions on your first attempt. Some require tools you won't acquire until much, much, later on like the Cargo Fulton.
