In 2011, Trese Brothers started making a game for Android called Cyber Knights, or Cyber Knights RPG. At the time, writing Android games was a hobby for the Trese Brothers. The setting was based on table-top games the brothers had played with their friends years before. Set in the domed city of New Boston in 2217, the player played a Cyber Knight who performed jobs for both gangs and corporations, developed a team, implanted cyberware, using small sprites and grid movements. Development of Cyber Knights Classic ended in 2017, around the time that the Trese Brothers created a game company and became full-time game developers.
Cyber Knights: Flashpoint is inspired by that classic Android game, which players now commonly refer to as Cyber Knights Classic. CKF is set 14 years after Cyber Knights Classic. Some of the faction names have been changed, and some of the history has been retconned, but the setting of Cyber Knights: Flashpoint is still recognizably the same as Cyber Knights Classic. A few characters from the old game may even appear in Flashpoint.
Cyber Knights RPG is still available for free on Google Play, along with a paid version named Cyber Knights RPG Elite with additional features. Unfortunately, the game does not work well on most modern phones. However, it can be played on Windows through Google Play Games for PC.
Here is the description of the setting of Cyber Knights Classic:
It is the dawn of 2217, and the world has ended. Megacorporations provide humanity's last survivors shelter in the vast dome cities of New Boston, New Berlin and others. Across the planet the Global Matrix has reunited the scattered survivors and reignited the fires of competition.
Technology has changed humanity. No longer merely flesh, many Cyber Knight have turned to nano- and cyber- technology to gain an edge and extend their abilities beyond human limits.
A global arms race has begun between the remaining megacorporations. Technological domination and control of the remaining metroplex are the only things that matter now.
In this cold war conflict the soldiers are called Cyber Knights. Elite urban mercenaries, they are expendable, deniable and effective. The megacorporations need them to do the dirty work in the grey shadows of the metroplex.
You will control a skilled team of mercenary cyber-warriors. Use turn-based tactics combat to deploy skills, equipment and cybernetic implants for maximum effect. Specialize your team members in stealth, combat or hacking skills. Dominate the megacorporate landscape with strategy, infiltration, battle prowess or be a digital ghost.
