Just beaten this, thoughts below:
+Usual high production values
+I like the fact you can choose missions etc
+Space combat is a nice detour from the usual on-rails vehicle missions you get in CoD, not up to Freespace 2 standards but at least it has a half-decent control system rather than the usual random garbage you get from CoD vehicles
+Some decent characters, builds a bit more of an emotive feeling towards squadmates
+I love squad based FPS where you fight alongside AI teammates, and this game had pleasingly few solo sections
+Decent array of weapons/attachments etc
-Game-breaking bug on the mission where you have to destroy a fuel tower - my C-12 never entered the room where it is supposed to fight an enemy C-12 so after I killed it the game was irretrievably stuck, as there was no C-12 to open the door. Had to restart entire mission ://///////////////
-Main story arc is very short, take away the side missions and you could probably nail this is 5hrs or so.
-Spacewalk combat is lame, especially the guaranteed kill grapples :/
-Main character needs a slap in the face. Just sayin'.
-Really really annoying unskippable spaceship launch sequence at the start of most missions
-Not quite as many memorable epic set pieces as you normally get from CoD, they pile on the teammate deaths but not that many single staggering events compared to usual
Overall the game feels kinda like an action-oriented Mass Effect 2, which isn't necessarily a bad thing - it just lacks the length/depth. This game is a bit weird, the first half is very, very good but it flatters to deceive in the second half. I also played through Advanced Warfare this week and to begin with I felt that this was superior, but I'm now walking away from it not feeling so sure.
