Speaking from the campaign experience only, where i feel mixed on it but leaning on positive and I'll try and convey why.

TL:DR
Pro:
Upgrade tokens per mission to personalize your future missions.
Custom missions with unique challenges.
Lack of self harm with explosives is fun for reckless play styles.

Con:
Some missions are Randomly generated and drags out in time while you have limited tools.
Lack of tools early to mid game feels restrictive weapon wise, prepare to use dual pistol 90% of the campaign
Lack of self harm with explosives creates terrible habits that breaks game balance in my opinion.

The problem is the campaign drags on once's you hit the mid point and it starts throwing huge randomly generated maps at you while you don't have all tools unlocked yet. This left me running dual pistols with both upgrades to both conserve metal because the assault rifle requires more to compete, as well as the other weapons wasn't unlocked until later. Once the RPG got unlocked I quickly learned that there's no self damage and I proceed to use it to fast travel through the cave walls, running face first into walls shooting the RPG to speed up the general flow of these missions. while it also was the best option for killing nests and huge enemies that have armour.

The feeling of the campaign dragging also comes from the previously mentioned randomly generated missions have between 20 to 25 waves, with each having 10-20 minutes between waves, yes you can speed up the waves to make the missions shorter, but the line of safety to avoid redoing the mission or reloading a save earlier, makes you risk averse until you have a doom wall or 2 depending on the enemies approach.

I feel mostly jaded from the lack of options as the campaign tries to drip feed you tools for each mission, the good thing is some missions are cool with custom designed challenges and cave layout, I just wish they had more of those and shorter "filler" missions.

If you decide to get the game now, I recommend doing the tutorial to know what to do and then proceed to do skirmish instead of 15 hours of "tutorial" as the final mission is essentially endless mode where you can use the campaign's upgrade tokens to go down better each run.

It was entertaining but some missions dragged down the enjoyment so be aware of that.
