I feel like they've tried switching some things up and throwing some unexpected stuff in campaign, (like the reverse door breach and the mission where you immediately get tear gassed, and how you can do stuff like shoot convoys or get spotted and still have a chance at completing the mision) and hey it has to be better than the recent BF campaigns.
The BF4 campaign is worse but to be fair they don't market it around the singleplayer.
In the second space mission, your rifle has an underslung grenade launcher.
There's also the fact that firing your assault rifle on full auto has absolutely zero affect on your inertia. None whatsoever.
