Some kind of free weekend going on Steam for this, looks like a DLC or some such.
I played the base game a little a year or two ago, was trying to make friends with a co-worker who loved the Destiny series but that didn't work out.
It seemed a bit on the easier end of mmoshooter but I don't think I got very deep into and kind of solo'd so I don't think I ran into the harder content before going back to Planetside 2.
EDIT so not to re-bump: I tried it again, seems like a pretty good game. There is a Legendary mode that felt about right on difficulty, though the quest I was doing required me at one part to defend a capture point to open a gate and it overwhelmed me with swarms of opponents at that point. I went back to standard difficulty to progress. I joined a few public events and started a mission other players apparently are recruited automatically to join. Otherwise I ran around solo because I haven't figured out how to flag for LFG or found a recruitment panel or such. It seems to go by Steam friends list which is a bad way to go since no one on my list is playing it, but I could risk pestering them with an invite to this game if I dug too deep into that. An in-game lfg system for (random) people already in Destiny 2 would probably be better.
EDIT2: Lololol I saw an ad on the steam login popup saying this dlc is $99 ($50 for dlc and $50 for season pass). I take back what I said, totally not worth what they are charging.Went from hey this game is ok to holy cow this game is a garbage overpriced time sink soon as I saw that.
