Although it’s an FPS, the gun fighting transcends standard “shoot anything that moves” action. The gameplay in Deus Ex: Invisible War is extremely deep and non-linear; you can solve any problem or situation by using any variety of means. Violence and gunfire, while certainly a possible solution, is not the only means for getting through a situation. You have a good many non-weapon items to help you solve problems through non-violence, like multitools, which allow you to bypass electrical locks or hack a subsystem. You can interact with NPCs you meet, get offered side-quests for extra credits, and you can interact with basically everything that isn’t bolted down, like grabbing chairs and chucking them across the room.
