Every enemy is a bullet sponge, time to kill is way too high. Breaks immersion and does not replicate what the weapons should do, it is not lore friendly.

The dialog is, for a large potion, not what you would expect a space marine to say, the voice acting is rather poor, not as bad as Assassins Creed Rogue but it can be quite jarring

Spoiler ahead relates to campaign progression:
The game introduces a Lord of Change, and you can defeat it. A Lord of Change could kill a Space Marine with thought and a wink of an eye. Same goes for Tyranid Neurothropes, their physic abilities are no match for a squad of 3 space marines, and sadly there's no introduction of a Librarian or any anti-psyker weaponry that make the encounters more immersive.
