Yeah, I think that's the default happy ending though there is a better ending and I think 2 worse endings. I think you can get the worst ending by just replaying the final fight and picking different options but the other two would require you going further back and probably some meta knowledge on how to get them. Not worth it if you didn't enjoy the game that much anyway. I'd still recommend the high level follow on campaign though. It's pretty short and ties up some loose ends.
I enjoyed the follow-up campaign, but hated the combat design. It's like every other enemy was a grenadier and 75% had the stun immunity cyberware. Stupid easy if you were a fire mage, a pain in the ass if you weren't and didn't get Duncan's magnet arm.
If you had to drag yourself to play the main campaign to the end though, it probably won't change your overall opinion of the game.
I'm kinda disappointed that HBS seem to have abandoned Shadowrun after putting together the engine and a ton of assets. Looks to me that they could make good money by pumping out more modules, both Dragonfall and HK were well received.
It was a combination of no-challenge combat (on hard), obligatory decking (still not fun) and a story that failed to hook me in - neither the foster father, crime bosses or brother are endearing or very interesting, and the big bad is just spat out 15 minutes before the finale because there has to be one.
The Russian and Japanese companions were the best thing about the game.
I was also expecting them to keep pumping out more modules.
