MGSV - This is how I farm (200,000 GMP per 35 seconds)

Deploy to free-roam with a tank. Once in free-roam, start the white mamba mission. Drive your tank over the mission start box... The rest speaks for itself
Each 35 second round gets you a large diamond and another tank. Just make sure you hit the checkpoint before restarting the mission. You can accumulate more than 100 tanks in less than an hour if you get in a good rhythm. Top 2 tanks sell for 100,000 GMP but I've been accumulating them lately now that I'm done with most research, makes your PF's durability rating skyrocket as you build up a massive tank battalion.

(You can complete this loop using the lowest tier stealth camo consumable and in standard fatigues, it just goes a bit faster in the Raiden suit.Just trigger the camo consumable at the top of the first hill and you'll be back before it wears off.)

Got to love how this mission has everything.

GMP, resources, a way to severely decrease your demon points and you also get to beat children while you're at it.

You don't have to use stealth camo or Raiden on this method, all That you got to do is go around to to your right side and then go up to the tent, go inside and grab the diamond and move! it could be possible that the kid close to the tent may see you, all you got to do is used the slow motion shoot the kid and get out of there from where you came from

This still works. Free roam, open the mamba mission, bring tank close to mission box. Start mission, fulton tank and get the diamonds and other. Retunr back to checkpoint w/o alarm, restart mission. Repeat again from the mission (after accepting the mission box).

people out here farming gmp like you cant just sell 5k precious metals and get your offline gmp maxed out

[jackmeriustacktheritrix]

can confirm still working in 2024, doing it right this moment, although i air drop a tank in instead of deploying to free roam with one, also don't have raiden or the "stealth camo" so i just use the basic sneaking suit and the 4-star stealth camo PP and it still works fine.

step by step instructions:
1. deploy to africa in free roam
2. select the white mamba mission from your i droid
3. run to the mission start area and air drop a tank near the mission start box thing BEFORE approaching the mission start box thing
4. start the mission at the box and fulton the tank then go get the diamonds and run back down the hill until you trigger a checkpoint
5. restart mission (abort mission also works but its slower because you need to select the mission again from your i droid)
when im finished farming i just abort instead of restart and then return to the ACC

You can Restart the mission as soon as you Fulton the tank then trigger the Hill checkpoint at 0:13 seconds. No stealth camo or speed suit required. You'll get way more tanks per hour this way.

Thanks man. Better than Occupational forces.

[steaketc]

this is how to bore yourself to death while playing mgsv

[farizindra]

What’s more impressive for me is DD were able to keep up with Raiden’s speed

[charlietr]

The way I do it is that one mission where you have to kill that guy in the airport, just use an rpg, killing him from the hill you start at. No detection or anything so loads of bonuses…

[vili-pekkavaltonen]

Also to produce that stealth camo it cost 400 precious metals.. which is 400 000 gmp

[truckerboypete]

Still working October 31st 2023, thanks, i do stunarm the whole lot, get the guard post captured heroism points, and i fulton the Wingate gun and mortar, cost's 5k each fulton but you get 9k for the mortar and 12k for the gun

[darkobakula]

Much more easier and effective methods of farming GMP out there. They take longer but in one run you can max out your gmp

[asyybrian]

it's work in 2025/04/28, thanks a lot!
這在25/04/28依然可用！

[MoHonda]

Doesn't work for the tank anymore, only the diamonds.

[sanguinetales]

They must have patched this cause I lost all of my New Tanks. How do you "end" the session without losing the tanks?
