How to access free roam in batcave?

[hinc94]

I've recently bought the game and completed a few levels, but have no idea how to free roam in batcave. There should be a place like the helicarrier in lego marvel for us to explore, buy characters etc. But I can't find the batcave from the map, any idea to access the free roam?

when you're not in level's you're in free roam. you can use the warp gates as soon as you unlock them to travel between the tower and places like batcave, hall of justice, and the moon. as soon as you unlock the character switches you can start buying characters, there's one by the trophy room(i think it is) in the watch tower.

Press M, you do not even have to use the portals in this game.
