4: Project IGI
Another classic from back in the day, Project IGI was a rather story driven game that dished out truckloads of up till then unseen realism in games. Soft cover, realistic weapon handling most noticeably. Taking shelter from enemy fire in a wooden hut wasn’t much of an option here. Also the game took some hints from Rainbow Six, requiring the player to operate tactically, without going overboard with guns blazing.
