They certainly did a change up after the previous games. This time instead of massive C&C like base invasions, now you are given a squad to attack with. This is more tactical and you can't just re-build people to make it less of a concern when your main character dies. Instead they fall incapacitated, but can be revived, though you have to get someone to get back their men for those in squads. I had a lot of fun with this and it felt closer to Warhammer 40K than the previous games and you could be tactical by taking up buildings or hiding behind cover for protection. Definitely worth a buy.
