The sequel to the interesting Ishar, Ishar 2: Messengers of Doom is a French, first-person RPG with atmospheric graphics and challenging party-based gameplay. It was first released in 1993.
Thankfully, Ishar 2 rights some of the wrongs of the first game. You can actually see where you are on the map now, which is a blessed relief, and the interface has been cleaned-up a bit, making movement and combat a bit easier.
