@ sergeant25: nope, try "Apopalypse" instead of "easy" and you'll sweat blood! BTW, got to level 427 before I quit, I think the max spawning is somewhere between lvl 110 and 150 and then can't get any worse...
Vanilla it's impossible to get far on apopalypse, but with double cash mode this is insanely easy instead... Started playing before I went to bed, woke up today and I'm now at level 209 and still nothing gets anywhere... Oh, make that 210 :P
Anyone find a working strategy for Apocalypse mode? Keep losing on level 57, can't figure out how to afford enough stuff that can wreck those damn MOABs...
