Round 43 Solo easy. Overall the map is really, really, REALLY easy on solo - especially with three regenerating Quick Revives. I actually suicided myself on Round 43 by holding the grenade too long (awesome way to die too!), but seeing as I had 3 Afterlives I had to do it three times. ^^ I did have everything too - Redeemer, Vitrolic Whitering, a regular BlunderGat upgraded (so much fun running the double Gat and Cherry combo ^^); all that was missing was the golden spork, but that's only because I was too lazy to get it.
