Tiertex Design Studios

Background
Tiertex Design Studios was a British video game company that was established in 1987. It primarily focused on ports of arcade games for home computers of the era, before shifting to console games in the mid-90s, and then to handheld ports of games in the late 90s. In 2003, the company exited the gaming market following complications with development and adoption of seventh-gen consoles; pivoting to USB development boards and industrial-purpose displays. Eventually, the company as a whole was shuttered on August 5th, 2021.
