odds are that over 995 of the people that say 0 deaths are lieing. i beat it in 45 once. ive beaten it 3 times. i have never made it passed level 15 without deaths. my least favorite level is 12. annoying. i hate it, i have no room to move...
theres a way to never be able to lose. get one country on a tip, give it a sniper, barricade and 24 mechanics. lasts forever. after like an hour, they must have at lest a few deaths.
