awesome game. trick is to max out amount of survivors and then use 5 points a day on survivors after that and use the rest for weapons. if you dont use 5 points or so a day then you lose survivors.
cool game but way to easy. just set up 2 walls of barrels and a wall of fake walls in the middle with 1 missing just in case. then rocket the crap out of a barrel wall and then set it back up and do it the other side. got to level 80 in nightmare with that then my hand started to hurt.
i had like 40 railguns but couldnt get any of them to combo =( around wave 340 then it takes over 30 hits from a railgun with all upgrades and support turrets to take out 1 guy!
