Endgame?

I really like the extraction shooter rpg type but i don't just like to wander around without doing quest or having a goal, so far i've done all the quest and level 30 it's been a moment. i was wondering what will be the endgoal?

Like in tarkov the goal is mainly to do kappa and do quest to unlock gun part at the vendor. But everytime i did kappa i just stop playing.

What will it be for arena breakout? What is the endgame looks like on the phone version?

Also do they plan to release more quest for the beta and some other map ?
