The story campaign in Call of Duty: Black Ops 7 has numerous restrictions tied to its always-online nature, with no method of pausing levels. You'll also be booted from your game if you're idle for too long.
Operation Harsh Doorstop is good for a military shooter, of which I’ve played in the past. It’s free to play too if I’m not mistaken (and the modding scene for it is quite fantastic as well).
