Alas, Square Enix shut the project down a few months after reveal.
As reported byPolygon, BlackJack Studio released a game called Metal Storm, or Mecharashi, in October 2024.
The trailer certainly looks rather Front Missionary.

Square Enix have sent a bunch of DMCA takedowns to get the game yanked from storefronts.
It’s back on Steam as of this writing thanks to a counter-claim.
Find some examples below.

They want BlackJack to both remove said infringing material and cough up $150,000 per infringement.
It reminds me ofPhantom Brigade.
Ah, I hope we get another tactical mech game soon, once the lawyers have had their fun.
