The only person to ever clear crimson shadow online was an 18 year old guy who went by Cro. He was the only one to beat it and now he was starting over from square one. But when he went to make a new character he got a message saying "would you like to up the stakes? start from square zero? and play the game of Life and death?" Cro thought what a joke and clicked yes thinking it would make the message go away. But what actually happened was he got sucked into his computer and transported to the game Crimson Shadow Online. After he got teleported there he got a system and that's it. The system didn't have a much... at first. But after he made himself look the way he wanted and, chose a class, he found out he had a system that gave him random perks as he leveled up. The perks were references to other games that he played a lot like call of duty, Halo, Skyrim, fallout, and other games he played. But that's not all it did. It also gave him additional abilities and powers that he has to unlock by leveling up and completing missions. But at first he thought his system was crap. He thought 'oh this stupid system only gives me perks that are ripped off from other games. this thing freakin sucks. how am I supposed to get stronger with only these crappy perks?' but little did he know that was only one of the lesser functions of his system. It also gave him additional weapons, attacks, and abilities that he only ever seen in videogames. His system was just about as broken as god mode in Grand theft auto. But he had to level up and stuff to gain access to all of his broken abilities.
