The series of games featuring everybody's least favourite high-vis wearing clipboard-wielding incompetent idiot, Percival.
(Yes, that's right, it's officially a series of games)
How did Percival end up making announcements on behalf of The Powers That Be???
Oh no. Percival survived.
And in this game, Percival finally graduated from being a mere '"funny" background voice' to being a 'genuine game mechanic with actual implications for the gameplay!'
Whether this is a good thing or a bad thing is up to interpretation.
The Entirely Unawaited sequel to The Button Factory (and not a sequel to Inconvenient Space Rocks), featuring Percival in Space!
This is not entirely canon to the overall Percival canon. This merely takes place in a seperate timeline, in which Percival decided to apply for a job at the Institution for Practical Parallelization instead of at The Button Factory. Thus, it can be considered to be an official spin-off.
This game was where Percival made his very much unwelcome debut. Everything went downhill fast from here.
