I can't believe someone actually mentioned that.tomtom94 said:
It lasted for one series. This series was cut short due to the September the 11th attacks and the brief period in which anything violent was seen as glorifying terrorism. As such there is an episode which has never been broadcast
It was a show revolving around paintballing, in which six members of the British public would go up against six experts and a load of "grunts" in order to defeat the "plot of the week", all the while earning credits which could be redeemed for extra ammunition/weapons. The team which earned the most credits by the end of the series would be called back for one final mission.
I saw it when I was much younger, I spent two weeks of the summmer holidays just re-watching all the episodes on Youtube.
It was good fun. Sadly Channel 4 didn't seem to notice this.
