At least the other animals grunt and growl if they get close enough.
You can come across an NPC strolling along the river, the entire scene serene and peaceful, when suddenly a crocodile shoots up, wraps its jaws around the screaming NPC, and drags them underwater. Crocodiles don't only try and feast on the player character.The next, you underwater as the croc has you in its jaws and in a 'death roll'. One second your walking along a seemingly safe river or standing in a BOAT. The crocodiles are living Jump Scares.It's made much worse when you're exploring the islands at night. It triggers a primal, instinctive terror to realize that you are being hunted. It's one thing to face down a raging feral dog, but it's another thing to think you hear a bit of movement and turn around to see an entire pack of rabid hounds slinking through the grass toward you. When animals hunt you, they don't just run up and attack either.Adding these animals in was likely in response to a complaint the fans had about Far Cry 2 that there were no predatory animals in the game.You can also often see the animals eat the people they kill.They don't know what it is, until suddenly the caged animal (bears, tigers, etc) isn't locked up anymore and is set loose and the AI find themselves being mauled. They're minding their own business, standing guard, when they might hear a wisp of something in the air (your sniping bullet). They quite often have caged animals in the vicinity. And this can also be Nightmare Fuel for the AI enemies.They can very much sneak attack you and can kill you very quickly if you don't fight back. Not just wild boar or hunting game animals, but tigers, bears, crocodiles, sharks, Komodo dragons and so on and so forth. That's not too bad, right? Well, as it turns out, there's all kind of animal life on the island too.
