Squads often circle you and come from all sides, using trees and rocks as cover. No other game has that. Others use predefined AI-waypoints/path to simulate or even script everything like back in the 90s.
Crytek produced Far Cry 1 and the next game was Crysis 1. The AI system evolved of course. On the other side you Crysis 1 also uses a lot of scripted sequences for cinematic purposes too. Far Cry 2-4 were developed by another studio based on a fork of the engine.
