Prey for Me

In an ultra secret research center, the government was researching how to create animal assassins. They wanted to drop a container of a gaseous agent into an area and let the animals kill the enemy. On a different sublevel, they were also trying to make dogs super intelligent to serve as spies. If they could teach them various languages, the dogs could scout on the enemy and report back. For the final sublevel, they were researching how to genetically modify insects to carry deadly diseases. Something in the research center goes wrong, the research gets out, combines, and animals begin to kill people. Only the canine family stands in the way. Will humanity survive an all out assault from every animal on the planet?
