What episode is this?
The one where the easygoing and thrill-seeking Cooper (Wyatt Russell) is roped into an all-too-realistic horror game.
What Easter eggs are there?
There’s quite a few references to previous episodes here, stemming from all three series…
To 15 Million Merits (series 1)
Quite an obvious one this: Sonja, Cooper’s new London friend is played by Hannah John-Kamen – the same Hannah John-Kamen who played Selma Telse in the series one episode (the first winner of X-Factor-style show Hot Shots). Could Playtest be showing part of Sonja’s past?
To White Bear (series two)
Remember that 8-bit-esque symbol plastered around the second episode of series two? That appears on top of the equipment that transforms into the hit-the-gopher-game.
To Hated in the Nation (series three)
A blink and you’ll miss it moment: The magazine Sonja holds up showing Shou Saito, CEO of Saito, also references a company called Granular. Of course, Granular are the company behind the killer bees in the series three feature-length finale.
