Welcome Back, Vector Sigma Players

If you played the Transformers Trading Card Game through Vector Sigma, welcome back.

Vector Sigma was one of the most prominent groups of the early post-cancellation community, keeping organized play, discussion, and original card development going after official support ended. In late 2020 it rebranded as Alpha Trion Protocols, and carried on under that name.

If you stayed with the group through that change, Welcome Back, Alpha Trion Protocols Players picks up the story from there. If Vector Sigma is where your memory of the game ends, read on.

The game continued to grow.

transformerstcg.org now supports the community game through new cards and full Waves, current rules, multiple formats, online and in-person events, free print-and-play downloads, professionally printed cards, Public Beta testing, and resources for new and returning players.

That earlier work has not been lost. Vector Sigma and ATP releases are preserved and playable through the Black Hole archive on the transformerstcg.org Tabletop Simulator table, and the ATP page covers what the group released after the rebrand.

The current transformerstcg.org card pool and balance environment will differ from the game you remember, but you do not need to learn everything before returning. Revisit the old cards, explore newer community releases, join a game, ask questions, and find the format or deck that works for you.
