It's all about the gameplay, the rules of engagement are different than a big budget shooter. This game is taking it back to the old days where there was no assist other than using a mouse.
This is the first time to my knowledge that this type of FPS is available on consoles. Well, actually Xbox indie program has had a ton of these types of games already but nobody tries them
this was during the 360 era tho. Xbox one recently started a new indie program but you gotta be somebody to be apart of it..
