10 Landmark Video Games That Were The First Of Their Kind

8. Half-Life

Platform: PC Pioneered: Intelligent Enemy AI Enemy artificial intelligence had been utilised in many first-person shooters before Valve's epic sci-fi series came along, but Half-Life was the first to do it well. The AI seen in Half-Life was like nothing before it, introducing greater challenge and a world that felt far more alive because of it. The commandos of Half-Life were the game's best example of enemy intelligence. They were capable of flanking the player, using a wide range of weaponry when appropriate, and not just stay in one place behind cover. Most impressively, enemies were able to communicate with each other, genuinely working as part of a team in order to take down the player. Rather than gunning down static models in a shooting gallery, it really felt like you were fighting against an intelligent, formidable force.
