Pretty much have to agree. I am playing on the hardest difficulty, and I'm starting to these missions were designed to be played in co-op. This is especially clear in near the end of the first mission, where some objectives are spread apart and clearly designed for multiple players to tackle them. The companion AIs are really dumb.Space Marine 2, pretty cool so far, even thought it plays kinda awkward. Like, the ranged combat feels really good, but considering the enemies you're facing, they will always be in melee range and dealing with ranged/melee is tricky. Plus, while shooting feels really good, your shots don't really stun enemies so you have to shoot, dodge then shoot against ranged attackers or take damage. Initially I had a lot of technical issues with it. Mouse pointer would cause huge lag, game crashed, etc. But that was all resolved by rebooting and installing new graphics drivers. So yeah, pretty cool, even though it does have its issues.
Also, those Zoanthrope can go fuck themselves; I don't understand why they take so much ammo to kill. If they are supposed to be designed as a support unit to the rest of the tyranids and tend to stay on the backside, doesn't it make sense for them to be squishy? IDK, maybe it's a difficulty thing.
Playing operations is pretty fun, because they have the side-story narrative of their own. Love how you can customize your armor sets, with all colors available to earn via gameplay. It's kinda sad that stuff like this is being celebrated when it used to be a common thing in the past, but now restricted with those live-service, battle pass, "cosmetics do not affect gameplay" bullshit.
