21 Testing... (feature)

21 Testing... was a 21 feature printed in TV Century 21, consisting of ten questions based on the characters and features from the pages of TV21. One question referenced Unity City, a location which had been introduced in The Daleks story Duel of the Daleks.

It was given in-universe framing, with the questions being presented by Agent Twenty One. Aside from 21, the feature crossed over with elements from other TV21 series such as Thunderbirds, Zero X and Captain Scarlet and the Mysterons. 21 Testing... also marked the first and only time that elements from the Doctor Who universe directly interacted with the series of Project SWORD and The Munsters in a licensed capacity.
