I have yet to play, only did the tutorial for quick testing. So I don't speak from personal experience, but from what I read so far.

Its more or less like the Splitgate 1. But they have a new game engine to better support and work on it (that's why its a new entry in series, instead an update). Some people say they don't like the hero abilities they added into. I don't know to what extend this is and how game dependent these are. But one huge plus point to me is a map creator for the community. One of the biggest issues I had in game 1 was that not enough content and maps were available.

On the negative side is, that there is a Battle Pass. At least for me this is negative, but the game is Free to Play. I assume everyone who liked the first game will like this one too, but can't be sure right now. They also seem to have too many players for their servers.
