I really love Spec ops: the line, its a very strange game that presents itself as a generic cod copy but becomes as the main character begins to lose his mind the game becomes weirder and weirder. Its based on Heart Of Darkness, the same book Apocalypse Now is based on. The game has a ton of essays written about it and even an entire book called Killing is harmless. If you dont want to read a book i would recommend this video. https://www.youtube.com/watch?v=wlBrenhzMZI
