Doom eternal is a great, fun, gory mess of a great time(game). There are frame rate drops and corruption errors i was seeing often sadly. It never took me out of the game, but it made for some stressful moments. Story, game play, polish and overall performance though is top notch and tops way past the first rebooted installment.
New enemy types, weapon types, executions, environments and overall feel to the game also cements it as one of the best FPS games so far this year and (in my opinion) one of the best FPS's in the last5 years alone hands down.
