Once a while ago everything was fine, birds and humans were good friends.
They lived together peacefully in a hilly landscape. But the area got contaminated
due to a horrific atomic accident and people had to move away.
The genetic code of the birds changed so they didn’t die but developed
harmful excrements that were fully contaminated.
In addition the birds got really aggressive and were
a threat to anyone who came near to them.
Your mission is to locate and destroy all of these birds’ nests before it is too late!
Once the number of birds gets too high there is no way of stopping them. Good Luck!
