Channel 4 game show

[bombingalong]

Can anyone remember the name of a gameshow that was shown a few years back on channel 4 which involved paintballing? Every week, a team had to complete challenges in order to win a prize, but trying to stop them on their missions was a group of gladiator/warrior style people. Both teams carried painball guns, and they could eliminate each other with a head-shot. I think it was presented by Dermot O' Leary abd I remember watching it on a Sunday morning.

Ta muchly for any help :-)
