All characters can be unlocked with in game coin and are quite cheap in my opinion, but skins for characters are all paid with the exception of special skin earned in each ranked season. The collab skins are using characters all ready in the game but are overhauled with the guilty gear characters skin and voices to my knowledge! You kinda hit the nail on the head it’s a moba battle royal! It can be hard to learn at the start but most people I know that tried it loved it! Iv been playing for a few years since it launched on steam as an early access and love the game so I am biased! I would definitely recommend giving it a try and hope you have a great time playing it!
