Honestly probably the most solid campaign I've played so far, it has alot of good things to it and introduces alot of good stuff to keep gameplay varied and fun
For the pros:
Every level feels unique, the first level has a random split decision dynamic that determines what type of enemies spawn throughout the level which is awesome
Level 2 introduces the Synthetics and for humanoid based enemies they were pretty fun and enjoyable to fight
And finally level 3 introduces stuff like automated turrets or landmines in another split decision for a level as obstacles for enemies to overcome and introduces more new enemies
Overall very pretty levels with alot of color and vibrance in contrast to the typical dreary environments of the other campaigns helps this campaign stand out on a visual level which is great that it stands out.
So onto the enemy variety, it introduces every synthetic enemy in the game unless theres one in the final campaign that I haven't seen and they are pretty varied: Pulse Rifle Synthetics will fire at you and Shotgun Synthetics will charge towards you in a attempt to maximize damage, you also got Synths with Shields, Explosive Synths, Working Joe's, Wardens which are basically the Pulse Rifle Synths but stronger in everyway and can throw grenades and 3 boss type Synths with my favorite of the 3 being the Synthetic Sniper.
It also introduces 1 new Xenomorph enemy in the form of a Spitter boss variation exclusive to the first level of the second campaign as one of the split decisions called the Irradiated Spitter and its pretty cool being stronger and tougher than a normal spitter with it firing burster type acid pools at enemies and leaving a burster like acid puddle upon death.
There's honestly not many major flaws with the campaign if any, its probably my favorite of the 3 I have played but if I had to choose one I do think the final missions ending sequence could have been better as once again it just boils down to the Point A to Point B Gameplay, I was really hoping for something like a Exosuit for example as a boss battle near the end and it can get pretty insane near the end but it's not great either
