You are an 18 year-old boy, you are under military training for 3 years because of the country's law that all boys at the age of 18 must be trained for at least 3 years

You can leave training after 3 years

You are in the training island along with 4 thousand kids-at-training. It's been a few days since training begun until, a group of the enemies planned an infiltration on the island, there's like thousands of them, they killed off all of the boys-in-training. The only ones left are you and Captain. Zack Handerson. The both of you are hiding in a bunker

"DANGIT! THERE'S LIKE THOUSANDS OF THEM AND TWO OF US, ALL OF OUR MEN ARE DEAD AND WE CANNOT CONTACT ANYONE!"
