Marathon Infinity's "Vidmaster Challenge" features remixes of three levels, the first of which is Try Again from the original Marathon. Each level includes grey, upgraded enemies.

A few notes about our playthrough:

We played Marathon and Marathon Infinity on Normal difficulty. We increased the difficulty on Marathon 2: Durandal to Major Damage to compensate for our somewhat higher familiarity with the levels of that game.

Big Time here is being played on Total Carnage; since the entire point of the Vidmaster Challenge is increased difficulty, there didn't seem much point in not playing it on the highest difficulty.

However, it was clearly designed for solo play where any death means a restart. We use irons' Co-Op script so that we share weapons and don't lose them upon death. We had some sync problems on playback as with the earlier vidmaster levels, but here it only prevented me from capturing Blackstar's chase camera angle. I have no idea why.

I think we're supposed to kill everything in this mission, although the sometimes inaccurate enemy counter still shows a few remaining when we hit the final terminal.

What a ride!
