He doesn't know how it got to this point. One moment, he and his team was being extracted from the enemy's hideout after a successful mission, and then their chopper was going down on an uncharted island. Much to his misfortune, he was separated from his team as they all had to jump down to avoid crashing with the chopper, and was hurt in the process of landing.
Now he was stuck in the darkness of the forest with nothing but his sniper, his gear, and a broken ankle. He was lucky enough to have his night vision goggles intact as the sun goes down. He was hoping to find his team soon without finding any wild creatures, but as he hides into the wild bushes after seeing something very strange and certainly not fully human heading his way, trying to be unnoticed, he was starting to already curse whoever crashed their chopper.
