To all you failing idiots!
This game is very easy! All you should know is how to aim. I kept my aim above 95% in the first 5 lvls, then with the machine gun it lowered and got worse from there. As for weapons I skipped: bazooka - beause it only has 1 load, slow reload, even though it's very powerful
and the zapper - because small load. Went straight for the Taugun after the flamer( this one is pretty good since it has a large spread effect and wicked firing rate)
The Taugun is pretty good, mainly because it has inhuman firing rate. The only downside is the rather small clip size, which is made up for by the amazing reload time (about .1 seconds)
After you get the railgun it's all fun and games and you just try getting that 100% destruction.
Also don't forget to clean, but not until the 5th wave or so, because you need to get that second weapon asap, whether it's the shotgun or machine gun. Don't forget to boost defense either, it's useful. I didn't kill a single bird in my 22nd wave and still had 95% cleanliness with 200 def. And wtf are you people whining about the pay? Just shoot enough birds and you'll have so much money you won't know what to spend it on and end up wasting it on defense. I mean FUCK!
I completed the game in under 15 minutes.
If you fail, you're either thinking too much, or you just suck. SPAM BULLETS, DON'T SAVE AMMO! IT PAYS OFF! Just shoot birds, it's that simple. This game is NOT, I repeat, NOT to hard! If anything it needs more levels.
