Final testing in progress; see you in Titan

We’ve entered final testing. The game now has the final features and functionality we wanted for this first version. We have a lot of ideas to add, but the game is already complete in its final version. And remember that there will be two additional scenarios for free to the game after its release.

And don’t forget the most important feature of the game: you can fight all you want. And you’ll have to fight, no doubt about it. But the key to winning is math. Without math, there is no victory. See you at Saturn and its moon Titan.


The novel that inspires “Math Combat Challenge”

“Math Combat Challenge” is a game inspired by the novel “Messenger of the Nastrond”. Sandra is the protagonist of the novel, set in 2156, three years after the novel “The entrails of Nidavellir” (Spanish: “Las entrañas de Nidavellir”).

This novel will be published in english and spanish.



Manual finished (english version)

The english version of the manual is finished. The spanish version will come very soon. You can find (almost) all the features of the game there. Some features are hidden, but that’s part of the joy. Click on the image to access to the manual.
