There were going to be two sequels, but it doesn’t look as if Iron Sky: The End Game is ever going to get made — and, if it does, the chances of its budget being so low that it’s even worse than The Coming Race are, I’d say, pretty high,
The best review of The Coming Race was by Jouni Vikman of Episodi:
”old jokes that would not have been funny even if they were new.”
It really is pretty bad.
Seriously … get a secondhand XBox 360 or PS4 cheap and play Wolfenstein: The New Order instead — it’s infinitely better.
