Level design looked promising. Unfortunately, the scripting is abysmal.

On the very first map: You keep going through the same trigger and it keeps activating hordes.
Then you come across a laser hallway - the pain triggers are too big to know when you're not touching the lasers, so it’s basically instant death for no reason. A campaign that does this always gets an immediate NO unless it can do something drastic to save itself.

Shadow Moses Island did not succeed in saving itself. The very next map, you get instantly obliterated by landmines with very little warning.
Right after that section, I shot an explosive barrel (Why not? It’s so inviting) only for everyone to instantly die because actually that whole section is full of nukes. No indication of that until you actually go into that area, though.

Trial and error punishment and terrible scripting work, a match made in hell. Stay away.
