[UPDATED 12/30/22] The game was removed from Steam earlier this afternoon and is only available on GOG.com as of this writing. Our original post from December 29th continues below.
GOG.com announced in their community forums earlier this morning that Raiden III Digital Edition will be removed from their storefront on Thursday, December 31st, 3 PM UTC (10am EST). The game is also available on Steam from the same developer and publisher however it is uncertain if the game will also be delisted there on or after December 31st.
As of this writing the game remains available on both GOG.com and Steam for $9.99. Thanks to Auster for submitting the news, I’ve added the date to the Watch List calendar and we’ll have a page up on the site later.
