Release Date:
This date is an estimate 4j Studios has already said it will not come out in Feb. my guess is early or mid March.


What are you looking forward the most?

*Note these things are not for sure and may come in later updates these are just educated guesses what is coming*

Also, 4j studios said very early on that there is a possible way to get mods like in the PC this is not confirmed and is just a little thing keeping you guessing what they might add.(They are full of surprises)
