Just played through it again on the PC, loved it on the 360 but didn't want to play through again on console at all. Really is a great game, can't quite decide whats better, guns or powers.
I played as a soldier first time through which meant awesome firepower, this time as a vanguard I think so mostly biotic powers, thing is I just as often forgot I had the powers to use while killing them with my shotty. The harder bits though being able to nuetralise groups of guys for short amounts of time is very useful.
Squad controls work but are relatively pointless, barely ever used them, its not a particularly hard game, tis all about the story really. NOt sure which I found more fun overall, I think the stupidest worst thing they did, was making you unable to use Snipers/assault rifles when not the proper "class". You can aim a pistol, you can aim anything else, a child can look through a scope and point it.
Limited firepower, something, but not being able to use them is fairly stupid. Still a fantastic game, can't wait for the new one.
Survey quests get you lots of money, you can normally buy an armour or a gun thats better than what the general current weapon drops you are getting are, but whatever you can buy is normally something that would drop on your next mission anyway.
Not sure tbh, do enemies scale to your level, or are they roughly set levels for specific missions. The end game was way easier this time, and I did more side stuff and the pinacle station stuff so was probably a good few levels higher.
