Finished up Longinus missions, unlocking weapons of gratuitous value, because they are just variations on weapons classes (actually this has been a FC4 flaw throughout)   :-|

Killed Yummy  :-O~~~

Killed Sabal   :-((  :-((  :-((

Hiked all over hell's half-acre blasting the living shit out of enemy vehicles and wildlife (bears, mostly) with the elephant gun  :-D

I still haven't needed, or figured out how to use the damn herbal injections for 30-seconds worth of supposed super-powers. It shows like a 5-key combo, which I'm not really motivated to work my fingers into the right spots for.

I never used a syringe other than for healing from start to finish (did the last mission tonight.  :-O~~~ )

I went down the same path you did, I've taken Sabal out and Pagan too. I believe there's various ways of completing these missions and letting them live, but for this play through I've gone all terminator.

TBH I thought there'd be more payoff of the story at the end, but maybe that's because I was a bastard and took out all the protagonists. :/

Just started the attack on Min's palace but had to abort because I brought the wrong load out, left the buzzsaw home.

I used to use the underwatery kits quite a lot when I was mopping up the loot boxes (I managed all but one from a time-limited level) and the berzerker one for occasional fun.

Yeah, that's not a mission that rewards subtlety.

I've still got a fair few hostage, assassination and hunting missions to do, so may do a bit of experimenting with the concoctions.

It's curious, but I've never had much trouble with Min's Palace. Maybe it's because I always play a really completist game, so by the time I get to the central mission climax I'm as well equipped as I can be.

I've always worked my way up the hill in a vehicle with a mounted gun for as long as possible, then gone off-road.

Don't forget to loot Min's body for a nice little Easter egg.

Oh I've got all the biggest and baddest on tap, but I like a bit of a challenge, so I swapped out the buzzsaw for an assault rifle before I knew what I was getting into, and brought the suppressed z93 (not especially useful), ripper SMG (very useful, but I reckon the spas will be more so), and the completely useless crossbow, will swap that for the one-hander GL.

Did you try shelling it with the GL from the buzzer first, or just charge in through the front gate?

I tried with the GL from the buzzer, but there seems to be a cap on how high you can fly in that area, presumably to stop you from flying over the top in a buzzer and shelling the place with the grenade launcher. I then tried hovering around just below the outer wall height and took a few guys out that way, but it was fairly banal.
In the end I stormed through the front gate, with the buzzsaw.

Did you both find that the ally AI was lacking somewhat? There were numerous times I drove away from a karma event or a liberated base and the golden path would literally walk into my vehicle's path instead of hoofing it away.

They're always getting mowed down by random drivers. They're also adept at stepping in front of my firing gun.

Yeah it seems the waves of attackers are triggered by walking into different areas of the palace.

Strange thing happened to me: I tried to throw a grenade, my indicator showed zero grenades (after I just did an ammo refill), then I used the mousewheel and it said 15 (full loadout), but when I threw grenades sometimes they just lay on the ground and didn't explode, and sometimes they did explode.

Yeah, they're not the best and the brightest, which is annoying when you lose karma after one of them walks under your vehicle or into your line of fire.

They're friendly and hand out cash. What's not to like?

The ones in FC3, if you accidentally shoot one, they turn their guns on you.

Finished it. The palace/fort/whatever battle was fairly epic, though not too hard with the GL/spas/buzzsaw combo (brought the elephant gun but never used it). I'm a bit disappointed at how passively Sabal and Min accepted their fate, didn't even have bodyguards, personal defense weapons, or attempt to escape.

¯\_(ツ)_/¯

FC4, too. When I finished one game, I tried to get the locals to hate me so much that they would always shoot on sight. You can do it within one session, but it seems to reset if you quit & restart.

Is Amita still alive?

You may already be aware of this, but there are interesting post-climactic cut scenes for both Sabal & Amita (depending which fork you took), both of which graphically demonstrate that they are becoming totalitarian monsters .

I watched the let Min live ending on YouTube and it concludes the story in a more satisfying way with a bit more exposition. In fact, I came to the realisation that Min is (torture scenes overlooked) a reasonably decent chap, even if he does have a thing for large choppers.

Amita was still alive when I finished the game, but I didn't see her pop up in any of the end game cut scenes. I think I got a radio message from her, but that was it. :/
