Final wave still wrecking me So, I can pretty consistently make it to the final wave with relative ease...but that last wave just shits on me.  At each chokepoint I have at least 3-4 thanatos, 8-10 snipers, 1-2 executors, 1-2 shock towers and a nice fat field of wire traps in front of the walls guarding all that.  Am I just getting unlucky with maps that force me to cover 7-8 points like this?  I'm clearing 75-100% of the map each time as well.
