Hello everyone! 

I managed to top out the Unholy Cathedral by getting stuck in a broken animation while the mission timer just kept increasing. When entering the execute animation, my character kept running in place, attempting to close distance to enter the execute animation. Since he could not actually start the animation he ran in place invulnerable to enemy fire for 30 minutes. Eventually I surrendered to exit the map.

Feel free to purge this score from the list. 

(PS. Great game! Thanks Neocore.)
