You have to take part in a clinical trial that will have you injected with animal genes, aiming to enhance certain abilities, senses and other desirable traits with the hope of coming up with a hope to gain a new way to enhance the country's infantry.

You'll be put through regular testing, observation, studies of your biometrics etc
