It's a great game, especially with friends in coop.

The swarms of tyrranids are a highlight, the devs made World War Z before and it shows.

Fighting the tide is pretty enjoyable, based on parry and finisher in close quarter and ammo management at a distance, classic stuff but competently made.

Story is straightforward but in a good way. It's no fat no bullshit open world, it has a satisfying conclusion, it's faithful to the Warhammer universe lore (the visual details are truth enough that the devs are fan, made me want to buy some minis).

This all sound like common sense, things you would expect in a new release but considering the level of the AAA market, it's a miracle.

The main enjoyment is the secondary missions where you get to have persistent progression: skills to unlock, equipment to upgrade, armor customization... the fact those are not in the campaign is a waste, worse it's not explicitly shown that those are the best gameplay elements !

It's like if GTA made the campaign a racing game and added the open world element in an undisclosed obscure menu.

Multiplayer PvP is okay, it's very team oriented and time-to-kill can be very short as a result. It's a great way to show off your customized armor unless you play as the bad guys who don't have much customization to offer (yet, it's on the roadmap, but what is not yet in the game should not matter here).

I can not judge optimisation, I have a PC build to kill Gods. Still it's long to load sometime (even on a SSD).

There are DLC for more armor parts, it's only aesthetic and there are many element to unlock for free by playing, no lootboxes.
