There is a mod for Single Player Tarkov, SAIN's that has, in my opinion, better AI than FEAR. It has some quirks sometimes, it's a mod for a game with severe issues at the end of the day. But the bot behaviors are really human-like while making human mistakes. The difficulty can be tweaked too, giving them worse or slower eyesight, better or faster aim, change the chance they have of making specific decisions. The game is a pain and it needs lots of mods to get good. Even then is still janky but that mod is so worth it if you miss something like FEAR.
