I came into this thread and saw tons of people crying that its shit.
Then i watched it and realized, NO, its not shit. Not at all.
Initially when he just walked around i was also worried how slow it was, then when the action started it got pretty fast, especially for a console shooter. And this is Doom for consoles, remember that.
They need to remove all the highlighting for demos though, seriously. They may think that people playing the game are fucking stupid and cant see that you hit an enemy enough that he is struggling so you can finish him, but most of us can. Just give us HUD options.
The basic gameplay looks great, i thought that it doesnt have enough enemies at once though. Needs way more enemies to make the action more crazy.
Enemy design does look a little generic, not bad but also not amazing. The shotgun and the rocket launcher look bad though, who designed those things?
Graphics are great. Remember, this is supposed to run at 60 FPS on those consoles.
