Tekkaman-James: Looks like the price of the game was silently reduced to $9.99, but the Deluxe add-on is still priced at $9.99 when it should be $4.99 now. I wonder if they will fix that soon. I'd much rather have the game on my shelf here, but when every other retailer is selling it for less, it's a hard decision to justify.
JLH: how do you initiate the dlc? it says the option should be available after completing the ending?
I beat it...then redid my save and beat it again after updating and the option still isn't coming up.
Tekkaman-James: The DLC becomes accessible once you have achieved the "canon ending" otherwise known as Ending # 1. You can see what you need to do in order to achieve this ending on
their wiki page. I hope this helps, because I accidentally spoiled myself a bit trying to find the answer for you.
:( sorry to hear the spoiler happened. I got an ending. maybe it wasn't the canon and was perhaps a bad ending. I guess i'll be finding out. thanks for the link.
