1. Crimsix
Crimsix is the GOAT of CoD. He started playing CoD 2 before he had an Xbox; he would go to a tech store and play on their demo Xbox for hours. Then, a few years later, he saved up enough money to buy a near-broken 360. He began competing all the way back in the early CoD 4 SnD scene, before going on to have the most ridiculously successful career in CoD esports. He's won 37 major tournaments, 3 world championships, numerous other smaller events, and oh yeah, he also dominated the early Halo scene back in the day (in fact, he's the only player who's been crowned "Major League Gaming Pro Player" in both CoD and Halo). C6 is also famous for creating the flex role in CoD, as he's strong enough on both an AR and an SMG.
There are numerous best of moments we could pick from, but if you want to see how much of a demon he is in CoD, then you should probably check out the SnD match versus FaZe at MLG Anaheim 2014, where he broke (and still holds) the record for most kills ever in a pro SnD match. | © Crimsix's Twitter
