Is this not being released on Xbox One?
No. Current gen and PC only.
Word of warning, I'm sure I read that this was developed by someone else (not the same developer of the first two). Could mean nothing, but worth bearing in mind.
Glad I'm not the only one that didn't gel with the 2nd one, I thought it was just me. I loved the first one, but quickly lost interest in the 2nd, I've been meaning to have another stab at it but haven't so far.
You can get it for £22.50 via GreenManGaming if you really want it . . .
PC version said to have a few bugs, so giving this a miss till it's patched. Looks great though.
