Just some feedback on the responsive kill reactions. I think it is a mixed bag. I played using the version that makes enemies the most alert, they detect you at long range, etc. I think that works better outdoors than indoors. For example, I was just clearing out the Alexandria Arms near the library, and after I killed the first raider, a wave of 4 others came to me, making it pretty easy to pick them off. Then as I advanced just a little bit, another wave came at me and I took them out. But after that, the building was emptied of them, except for one. All the raiders were dead within 5 minutes of entering the building. It wasn't the sneak, creep forward place I remembered from prior runs. And the raiders gave up some pretty good defensive positions that I remembered having to pry them out of in prior runs. It made the rest of the building boring.
I think I'm going to go down to the next level - the long range detection just seems to bring them to you too easily - indoors at least.
Just my experience in case anyone is interested.
Well in a way thats whats intended, bringing the enemies to you I mean. I understand that it may not be optimal in all cases.
Because RKR's long range detection has nothing to do with the default detection AI, as it uses a custom formula for detection, once the enemies move towards you, they still havent really detected you yet. The goal is to steer them in your direction so eventually the "real" detection kicks in, and they switch to more sophisticated combat behaviour (that is, more sophisticated than simply running towards you with their weapon drawn
). If you set reaction mode to 3, enemies will addtionally fire their weapons at you while engaging, again, without having actually detected you yet.
Outdoors this is supposed to solve the problem that there's a safe distance, which is still close enough for easy headshots, but too far away for the enemy AI to detect you, so you can basically jump around in plain sight without any negative consequences. Long range in this case means up to 5000 game units away. From my experience, you cannot get good detection results at this distance by simply adjusting game variables without breaking it for all closer ranges.
So if you're playing sniper-style I'd really recommend using detection mode 3, because otherwise there's little challenge. It will require you to pick a good spot for your first shot, avoid detection as long as possible, and quickly change positions after. For mid to close range on the other hand, it might suffice to rely on the default detection. So if you're mainly using assault rifles or pistols, I'd recommend detection mode 2, or if thats still too much for you, 1 with a very low event volume. Of course you could also disable it, but then it will be like before so that instant-kills are completely ignored by any actors.
