It's pretty much the same thing, but with a longer grind towards the final levels. Legendary bosses (jetragon, frostallion, centaur knights) were bumped to lvl 55, there's a couple of "alien" pals from semi random, timed events (meteorites), and a "final" dungeon as an offshore oil rig, which is filled with max level syndicate goons that can kill you really fast, but there are many places you can stay where their AI will effectively break. The game crashing while you're there is a much, much worse enemy
