(Not seen in the U.S.)
The UK received an airing of the Lockdown event, but it apparently got its own custom version of the Lockdown game. Unfortunately, I never played this game, few if any U.S. viewers played it or were even aware of it, and UK Toonami fans didn't visit Toon Zone or any other common U.S. Toonami hangouts.

There's no trace of the game files in the Internet Archive, so the likelihood of recovery is non-existent.
The only other possibility is that these screens are only mockups. These were produced as previews for Cartoon Network to see what kind of game they would be buying. If so, the finished product was quite different.
Google lists Playerthree as a United Kingdom website, so the first hypothesis is probably correct. Playerthree most likely adapted Lockdown's art assets into an action game rather than a turn-based, RPG-like game.
The Playerthree website recently went through a redesign and any mention of Lockdown was removed. Unfortunately, the Internet Archive didn't pick it up either, so these images and my previous post are all the evidence that remains of the alternative Lockdown.
