Well there's not been a whole lot really
We've had the gunner update (new guns, buffs, and fabulous new armour) and a couple more vanguard missions have been added
but outside of that?
not much really
sk is still a pretty fun game to play though, just find yourself a good guild and just have fun with others

I promised myself I would come back if OOO ever open the core or introduce more lore/story.
That's a thing that happened. Both of those.

Overall the game's content is pretty slow, but it hasn't completely stopped. If you're playing the game for new enticing things it won't keep your attention very well outside of promotional boxes, which have been coming out every two weeks since elevator fees were removed. So the fact that the front page is full of box promotions just means that we haven't had a huge update for about a month or two.

The game is still what you fell in love with all that time ago, and if you're coming back for that game it's still here. If you wanted it to change, for better or worse, it really hasn't gone too far.
