Not had a single defeat on mine on madness and done over 250 runs so far. I think it came close a few times to be fair but Alex just seems to be able to power through even on his own at the end. Alex is a worthy Eddie I have found - he really does seem to be a one horse power survival machine compared to most if any others hence why he can do NotB level pretty much on his own - which is crazy when you think about it!
