Nice concept and well-executed... very replayable. Difficulty scales well, even knowing where most countries are I've only gotten to level 8 so far. Agree with the comment about unknown-city-in-large-country should be worth more than unknown-city-in-small-country.
sort of a cross between amorphous+ and ether cannon. "50 deaths" achievement is excessive (died like 35 extra times just to get it), and "untouchable" as well as the impossible badge should respect if you have a shield or not. also not sure what the gold bullets do... thought they might 1-hit everything but that's not the case. permanent achievable upgrades and more enemy types would add to replayability. solid game otherwise, 4/5
urgh... survival wave 19, and that far only with my comp lagged with other stuff to slow things down XD. rockets + big mortars seems to be best, homing missiles are nice but not strong enough for the 4 tanks or the all double shooters levels... yeah they kill everything but not before u get hit a bunch of times. no tank levels and i might get 20....
pretty bad lag late when holding down fire button (down to like 3 FPS). otherwise nice game, could use more enemy upgrades - things that require you to adapt, not just get triple shot and win :)
LMFAO @ plastiqe, well played. :) i just started in madagascar and STILL LOST. somehow Argentina closed everything, and indonesia, australia and new zealand were untouched. how does a virus with no symptoms, zero visibility and zero lethality cause all the governments to shut everything down??
A question on city siege mode - does it repeat after wave 20? I'm on wave 23 and 21, 22, and 23 were the same enemies as 1, 2, and 3. Warrior+cleric+summoner+mage and health/power regen FTW :)
