Vietnam

A Sonic Adventure 2 cartoon about a platoon in the middle of the jungle, suddenly attacked by a giant gorilla that comes out of nowhere and murders nearly everyone.

The survivors gather an army of mostly young men to hunt the gorilla. On their way, one of the survivors gives a huge speech. They arrive and set up camp. It is a lot like Minecraft except the enemies are way harder.

The gorilla shows up and attacks the boys, but most of the platoon is wiped out. Now he is a giant rock monster being fought on the beach, but since he is made of rock the rocks don't do much to hurt him.

Now he is Springtrap. He catches one of the platoon members and locks him in a cave to starve. After a while Springtrap is killed and they rescue the platoon member using a TXT file dropped by the monkey/rock monster/Springtrap after he dies. The rest of the show is presumably about hunting all the other gorillas on the island.
