much easier if you don't repair any barriers except in the upper right hand room. on NM in the later rounds put ring of heavy turrets and alternate between keeping zombies off barriers and those coming in the bottom.
the danger percentages make no sense on nightmare. Far more people die on missions with a 6% danger rating then on normal. You should make the percentages stack harder by having more zombies around, not make it impossible to keep people alive.
like the graphic style and everything but there is something funky with the game loop. The frame rate goes up and down sporadically, sometimes going way fast, sometimes going way too slow, no other applications open, using google chrome.
don't put a game on this site if you are just going to hopelessly cripple it unless we play it on your own site.
As in, locking most of the weapons unless we play on king.com.
This kind of bs should be banned from kongregate.
