Another thing is that it is funny is how the pilot must be saying to himself on level 3 "Oh no it is a civilian house that is not firing on me I should shoot it instead of the swarm of enemies around me"
As far as the actual gameplay and graphics this game has a striking resemblence to a game creating program that I used at school last year. In fact Im almost positive it is the same because all thats different is the graphics and different ships which can be easily downloaded. Overall though great game.
I agree with the rest of the upgrade hangun and precision comments here, but also ZitS? That's likely not the best name to use. Not to mention it is too repetitive and I can run through most of the zombies in the streets while taking minimal damage, and just using my never ending supply of healthpacks that are lying around. I gotta rate this fairly low.
After many Months of hordes of zombies we have made this once hostile land into a prosperous city with 15 churches, 15 bars, 36 farms (assuming big farms count as two), 1 graveyard, 1 EVIL graveyard, 1 townhall, 2 (broken) malls, and 6 police stations. The population of 108 are a group of 24/7 drunk, religious, schoolworthy farmers consisting of 1 dictator/leader (me), 1 builder, 1 scientist, and 105 soldiers. We're ready for anything.
As far as controlliing the elevation of the plane in context to the wind it has great physics. And then we turned into a penguin when we hit the ground XD
