I'm sure the game will be fun, but it's no wonder the publisher Krafton tried to prolong the release date. It's an embarassment the state this is released in. Poorly optimised and dependent on frame generation, with content missing that they will slowly drip feed like they did with Below Zero.

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.
